Confidential

Architect/Developer

• Wrote “Domain Builder” tool to generate code for Domain and Application layers that makes use of an underlying architecture/library, given a database instance. The tool creates Entities with field and business rule validation, Domain and Application Service layers with common CRUD methods, an “ApplicationContext”, which wraps lazily-loaded anonymous Repositories, Entity Framework Mapping classes, the Entity Framework derived Context, application-layer contracts, Controllers for ASP.NET MVC and WebAPI and Domain enumerations.
• Created application architecture all new applications are being written with and all old applications will be re-written with. Architecture handled common concerns such as database access, security, data validation, caching, object mapping, serialization, encryption, logging, application configuration, templating, queueing, testing and client and server side entity change-tracking. Along with the Domain Builder tool, client code developers can quickly create new screens without detailed knowledge of the plumbing and underlying technologies. I wrote a 100 page (and growing) document detailing the architecture, each API/sub-system, each class and how to create an application based on the architecture.
• Trained junior and senior level developers on new architecture, helped devise solutions to meet business requirements and assisted in creating requirements documentation.

• Created distributed service using WebAPI to assist third-party vendors in creating the company’s SalesForce application.
• Created MVC application to host one-off “extensions” of core product management system.
• Technologies used: .NET 5.1.2, C#, .NET Web API 2.0, ASP.NET MVC 5, JQuery, SqlServer 2008 R2, Entity Framework 6.1, AutoMapper, ValueInjecter, StructureMap

Confidential

Architect/Developer

• Created solution framework/architecture for application to query national oil rig data geo-spatially and via multiple form-based selection criteria-sets.
• Wrote all screens of application with ASP.NET MVC 5, Telerik Kendo UI controls and JQuery. I used Entity Framework 6 for the backend with a generic repository implementation.
• Application relied on five different domains/database schemas, two if which I designed and implemented. For each domain, I created a separate domain solution to isolate domain business logic and control database access. This also allowed us to reuse this functionality in other applications.
• Main content of application was a SPA app that consisted of a “QueryBuilder” panel for form-based selection (6 complex forms), Map panel for geo-spatial selection and a results panel, consisting of multiple dynamically-generated grids, with various grid configuration and export options. There was a “Saved Searches” section for persisting user-wide and system wide searches, which were used to later rehydrate the selection forms criteria and map selection for further configuration and/or scheduling. There was a “Schedule Search” section to schedule searches to be performed on regular intervals. There was also a fairly comprehensive administration section that interfaced with a “Portal” authentication system I created.
