I am a professional developer with many years of experience. I have developed countless desktop applications, server-side processes, and websites. I am an expert database administrator with considerable experience using Microsoft SQL Server. I have developed software that accesses databases that are larger than 500 gigabytes, with more than 25 million records, dealing with concurrency issues related to hundreds of transactions per second. I have worked on projects alone and led teams, using Agile based management tools in both cases. My work is thoughtful and organized, and the quality of the final product will reflect this. I am primarily a Microsoft developer. I have been using C# and the .NET framework since its release in the year 2002. I have developed all kinds of services, desktop applications (including WPF), and websites (including MVC and Blazor). Before that, I worked with such things as C++, Pascal, Delphi, Basic, and even Assembly. I've been using Microsoft SQL Server since the year 2000. I am comfortable with installation, maintenance, and tuning; report writing with SSRS; import/export with SSIS; replication; and programming with Transact-SQL. I already had plenty of experience with database development using Visual Foxpro, Foxpro for DOS, dBase, and Clipper (ahh, the good ol' days). Since 2021, I've been working fulltime on my own MMORPG called Serdika. I'm using a customized version of EQ Emulator for the server and developing my own game client using Unity. Check out "Serdika MMO" on YouTube to see my progress.

Profile After graduating with an engineering degree, I spent 4 years in the software development world. There I learned a lot about managing customer requirements and desires as well as taking product from conception to completion. Afterwards I transitioned to a systems engineering role. I have found that a software background facilitates abstraction skills as well as enforcing requirements/functionality driven design work which is standard in the systems engineering community. In my systems engineering role, I have focused primarily on technical rigor in our systems model. Additionally, I have emphasized engineering processes as well as functionality and requirements led design work to ensure first time quality and depth of engineering design analysis.

I am a sole developer offering application integration with Open Data, Systems Integration with existing proprietary development solutions using a custom, extensible framework, business process automation/streamlining by utilizing custom developed applications to offload boring/repetitive/error-prone tasks, and blending of web applications and traditional desktop applications using in-house developed frameworks and application front-ends to create a seamless interface for employee interaction. This assists in employee retention due to lower attrition from confusion/difficulty memorizing the different systems, decreases time to complete across the board, and provides a more confident face to employees as a whole. I also provide Data frameworks, with APIs to abstract data collection from hundreds of disparate API locations so that management of data sources is seamless and painless. I also have 2 child brands: one that provides local political/demographic data delivered via a custom, in-house developed web application; one that as of right now is planning to launch a web application that uses Open APIs to utilize facial recognition and body conformation recognition to match user supplied photos of their pets with pets that have shown up at shelters in the vicinity.
