Senior Developer, Elsevier
January 2012 – October 2012
- For each application developed I worked closely with business sponsors and team leaders to generate requirements, user stories, and technical designs.
- Some of our UIs made use of Twitter Bootstrap, so I developed an open-source, reusable tree control that could consume arbitrary JSON objects and turn them into a navigable UI. Custom tree events could then be handled in external code as the tree was manipulated. I used this to create a prototype for a proof-of-concept web IDE, where a JSON object with file references would be loaded into the tree, and when a user interacted with each file reference it would load the file from the platform into a tabbed text editor.
- I created a custom piece of strata middleware that intercepted upstream requests and determined which data source should be used to fulfill the request based on the path information that strata provided. This allowed the platform to dynamically “mount” data stores to URL segments as needed, and gave calling code a uniform API for data (instead of having to know about each data store independently).
- I conducted extensive research and gave presentations on topics of import to the project, such as UI libraries, cross-domain iframe communication and browser sandboxing, user experience recommendations about how and when to save data in a user interface, etc.
- Performed project maintenance tasks such as building automated jake tasks, managing and updating NPM packages, rebuilding binary dependencies, filling out unit test suites (mocha/chai), breaking up large node modules into smaller modules for maintainability, creating README files for modules and apps, adding documentation to the wiki, etc.
Senior .NET Developer, Fpweb.net
December 2010 – January 2012
- In an effort to save time for the engineering team, reduce the cost of setting up a shared SharePoint instance, and provide customers with much quicker service, I consolidate the shared hosting site setup functionality and automated the basic setup process. Engineers would typically use a number of PowerShell scripts that would be executed manually in response to a customer order. I deconstructed the scripts and divided them into functional parts, then used the .NET PowerShell libraries to automate their execution in response to orders placed on our public website. My solution was highly extensible: each step in the provisioning process was encapsulated and placed in an execution pipeline, the inputs of which were the outputs of the preceding steps. The solution was designed so that additional provisioning functionality could be inserted into the pipeline by extending existing classes.
- I was also responsible for handling specific portions of the data migration strategy, specifically being able to synchronize product price changes made in local systems to our billing provider remotely, in bulk. This allowed management to bypass the inherent limitations of the billing provider’s user interface and edit the prices of multiple items at once. Also, because our products were informally categorized in hierarchical relationships (informal because the billing provider’s system did not support such relationships), it was necessary to propagate price changes through a hierarchy of products, allowing management to change the price of the “topmost” product–a change that would be replicated throughout the tree. I created a command line utility that would perform these operations based on price changes that management would specify.
- To eliminate the rigidity of our existing billing system (an IBM AS400), and to give management the flexibility to define products and services in ways that allow us to accommodate a variety of customers and their specific hosting needs, our team migrated all existing billing information from our legacy system to a cloud billing provider. I was primarily responsible for creating a data sync solution that would pull data from the cloud billing provider and store it in an on-site data store for disaster recovery purposes, reporting, and to be accessed by internal applications. My solution used the WSDL endpoints provided by the billing provider, as well as their CSV-based reporting interface to consolidate data from the billing system, and write it to our internal data store. The synchronization service used several threads to run different synchronization schedules (an incremental synchronization every fifteen minutes, and a full synchronization once a day). Each thread communicated its status to the other so that two synchronizations would never happen simultaneously. The software was installed as a Windows service, but could also be run ad-hoc as a command line executable. It was also responsible for failing gracefully if particular errors occurred (e.g., unable to communicate with the remote service), and to issue email warnings if it failed for unknown reasons. This service is now indispensable for the company CFO who uses the local data store to generate financial reports that he cannot obtain from the billing provider’s user interface.
- Our company standardized early on the Chrome browser, specifically because of its advanced HTML5 support, but also because it has a robust plugin system that we wanted to leverage. Company employees typically use a variety of systems, some internal, some external. While we do not directly control external systems, we were able to leverage Chrome’s plugin support to “add” features to external systems that otherwise would not be there. I was directly responsible for implementing a universal feedback form on all sites that employees use in their daily work. I created an HTML5 interface and a Json service that would consume data submitted by the form, then added scripts to our Chrome plugin that would inject the form into specific internal and external web applications. As a result, company employees can now submit bugs or requests to the development team from any web application they use. This feedback is piped to our task management software (AgileZen) via web services, and we are able to review all requests from employees quickly and effectively. This has become a very popular feature.
- I was also responsible for performing maintenance work on all internal applications and our public website. This usually consisted of bug fixes or small feature requests, or integration with other systems so that data could be shared or viewed by specific employees. I also contributed a significant amount of Wiki documentation to our team’s internal knowledge base so that other team members could quickly digest and be productive with code that I had written if they needed to change or enhance it.
Web Services Developer, Lipper, A Thomson Reuters Company
July 2010 – November 2010
Technologies: C#, .NET 4.0, Windows Communication Foundation, SOAP, Oracle 10g, Subversion, CruiseControl.NET, MSTest, Bugzilla, Fiddler
- Developed publicly exposed, secure WCF services to fulfill the feature requirements of the Lipper Investment Management desktop application product. Â Standard XML serialization was used for message contracts to fulfill SOAP 1.1 conformance requirements.
- Worked with Oracle development team and desktop application development team to design services that were efficient, met performance requirements, and adequately encapsulated business rules. Â Web services also encapsulated communication with other company systems, such as the financial analytics cluster. Â Because financial data is time-sensitive, stringent performance requirements were followed, and often required services to execute logic that would acquire data on separate threads, consolidate it on the service thread for caching, and then deliver it to the client.
- Designed, implemented, and documented a multi-threaded task registry that could be initialized with any number of “tasks” at application pool startup and run each of them concurrently until the application pool terminated, or the specified timeout for a given task occurred. Â I created an initial task implementation that would check the analytics cluster endpoints for connectivity, appropriately marking given endpoints as available or unavailable. Â Services that required connectivity to the analytics cluster would then request available endpoints from the task, and connect as needed. Â This guaranteed that unavailable endpoints were never accessed.
- Designed, implemented, and documented an XML-based health check monitoring subsystem which would check service connection dependencies and determine if a service was available or offline. Â Each dependency that implemented the health check contract would, in turn, check its dependencies, and a consolidated report would be returned to the user from the public facing service method.
- Helped maintain a suite of unit/integration tests which were used to verify the performance level of active services, as well as the accuracy of data returned from them. Â Created new tests when adding new services or significantly altering existing service functionality.

- Contributed to the standardization of CSS layout rules.Â Converted many legacy table-based pages to CSS layouts to eliminate excessive markup, promote style reusability, and achieve cross-browser consistency.
- Tested all new and converted web pages in IE6, IE7, and IE8 in order to meet client expectations and needs.
- Created new and updated existing ASP.NET template-based server controls that were used in various places throughout the application.
- Updated the data access layer when needed.Â Created and modified SQL DDL scripts, stored procedures, functions and pre- and post- deployment scripts.
Senior Developer, USfidelis
May 2008 – January 2010
Technologies: C#, .NET 3.5, ASP.NET WebForms, ASP.NET MVC, Windows Communication Foundation, Windows Presentation Foundation, LINQ to SQL, Entity Framework, SQL Server 2005/2008, IIS 7, Visual Studio 2008 Team System, Team Foundation Server 2008, Subversion, Team City, MSTest, NUnit, RhinoMocks
- As part of the company’s growth strategy, I split the existing corporate website into three distinct websites and augmented the functionality of each. All websites were written leveraging the .NET 3.5 framework.
- I implemented two static mock-ups in ASP.NET MVC and worked with the design team to make sure web standards were followed.Â Functionality from the primary corporate site was migrated to each secondary site, respectively.
- I wrote numerous Windows Communication Foundation web services to form an application tier which masked the underlying application data model.Â Each website consumed WCF services directly.
- I created a data model for each website in TSQL and used LINQ to SQL as the object-relational-mapping tool to interact with the data store.
- I added NUnit unit tests to each secondary site and used RhinoMocks to simulate application dependency functionality in each unit test.Â A Team City build server was deployed for continuous integration, and unit tests were executed for every source control checkin.
- To bring additional revenue to the company, I finished the re-design and implementation of the primary corporate site and worked with marketing on several web traffic campaigns using Google Web Analytics and Frontline Analytics.Â I also ensured that all regulatory compliance tasks were implemented in a timely manner.
- I re-factored the primary corporate site to eliminate code duplication, break up dependencies, and ease the maintenance process.
- I worked closely with the application administrator to clean up old environments and implement a standardized promotion process whereby each website was thoroughly tested in internal and external environments before being released.Â Each environment (development, staging, and production) consisted of a single IIS 7 web server, load balanced IIS 7 web service application servers, and a replicated SQL Server 2008 instance.
- To promote consistent release schedules, I worked with the project manager to re-factor Team Foundation Server source control and develop a change management process.Â We decided to use a semi-agile approach with small iterations and quick feedback.
- In order to mitigate the technological risks of re-engineering the existing line-of-business application, I was assigned to research, prototype, and make recommendations about chosen core technologies.
- Windows Communication Foundation (WCF) - I demonstrated that WCF proxies could be constructed dynamically by wrapping WCF’s ChannelFactory<T>.Create() call in a custom class that acquired all endpoint settings from a custom data store. I also documented all WCF binding settings that directly affected our environment(s) for quick reference. In addition, I was tasked to demonstrate how clients could receive WCF messages on parallel threads and marshal those messages to the UI thread when UI updates were required.
- LINQ to Entities - After evaluating LINQ to Entities 3.5 and concluding that lack of POCO support, customizable entities, and self-tracking entities (in a disconnected state) were severe hindrances to our project, I began evaluating LINQ to Entities 4.0 beta. I created a proof-of-concept project that demonstrated the new T4 entity templating engine with customized entity templates, and self-tracking entities across a WCF service boundary. Problems with entity object graphs and maintaining entity state after database writes led me to conclude that additional ORM research was warranted because LINQ to Entities is not sufficiently mature.
- Windows Presentation Foundation (WPF) - I evaluated several possible design approaches for WPF user interface views, including Model-View-ViewModel (MVVM) and the Prism framework. We decided to use Prism due to its compatibility with Silverlight, it’s robust EventAggregator messaging system, it’s use of Microsoft’s Unity Application Block for dependency injection, and it’s support for reusable UI regions. I also demonstrated that WPF can enforce action-level security through its commanding system and control-level security through its visual and logical tree helpers.
- log4net - I demonstrated the robust logging capabilities of log4net by creating a custom WCF appender class that sent log messages to a WCF service asynchronously. Since our client applications live in a disconnected state, this will provide a tremendous benefit to developers who will no longer need to ask users to provide physical log files for debugging purposes.
- ININ ICELib - I evaluated ININ’s .NET API for their voip telephony system in order to determine if we could integrate call center functionality into our applications without using ININ’s standard client. I was able to connect to the server and perform all basic telephony tasks from within a WPF test harness.
- As part of the project leadership team, I took the initiative and wrote several standards documents for the team to consume.
- Coding Standards - Our coding standards document details mechanics of good variable naming conventions, commenting code, exception handling, etc., as well as best practice guidelines for refactoring, .NET Framework usage, event handling, etc. Coding standards were routinely invoked in code reviews to ensure that all developers were consistent in their practices.
- Solution Structure and Namespacing - In order to enforce consistency in Visual Studio solution/project organization, I created this standards document with code organization guidelines. All new projects adhered to its general recommendations.
- Source Control Structure and Branching Strategy - This document was developed in conjunction with our iteration plans to ensure that teams were working in appropriate source branches during development phases. All .NET library dependencies and database were moved into source control as well.
- Performed maintenance work on an existing legacy line-of-business application in preparation for a critical re-write
- Participated in numerous requirements gathering focus group sessions, as well as executive-level steering committee meetings to determine the shortfalls of the existing line of business application and triage feature requests
- Prepared initial documentation for new application architecture, focusing on the business domain and key functional specifications (artifacts included UML diagrams, risk assessments, a vision document, an integration document, etc.)
- Led a design patterns workgroup for existing developers to help educate and empower the development team in preparation for development on the new application
- Contacted third-party data and service vendors and analyzed external APIs in preparation for application integration
