I'm a problem solver that helps extend the life of your legacy code. No matter if your code base is under ten years old, or is older than myself, I can help add new functionality.My primary languages are C++ and C#, but I have dabbled in JavaScript (D3, React, Angular), HTML, CSS, Python, VB6, VBA, and Java (way back, pre-graduate school).

Software EngineerBitscopic Oct 2022 - Apr 2023Palo Alto, California, UsI enhanced the backend of an ASP.NET MVC application that was being updated to .NET 6. I added new data reporting features for data pipelines, implemented various bug fixes, and updated code from .NET Framework. I also managed the migration of its backend database from SQLite to MS SQL Server, which included - Analysis of the SQLite database to determine the datatypes to use in MS SQL Server - The writing of code to create the tables in MS SQL Server and transfer all the data from SQLite - Modifying queries within the C# code base to successfully access the MS SQL Server databaseTo further assist with the database migration, I also wrote Python code to integrate a RabbitMQ messaging service with an existing data pipeline to ensure no data would be lost in the event of a server outage/failure. -
Software EngineerHaverly Systems Inc Jun 2017 - Sep 2022Denville, New Jersey, UsI led the redesign of multiple desktop applications from Visual C++ to more modern frameworks utilizing WPF/XAML for the front end and C#/.NET for the back end. Early work involved using .NET Framework 4.0 and later rewrites were done using .NET 6. We coordinated with other engineers that managed different back-end components and with sales/clients to determine current pain points and how they could be fixed/addressed.I wrote an Excel Add-In using VBA to create mathematical approximations (generalized quadratic equations) from given data sets. The Add-In performed statistical tests (R-Squared and Adjusted R-Squared) to determine the fit of the approximations. These approximations were used with another application that made heavy use of linear programming to solve optimization problems, significantly improving both the run-time and accuracy of the models.I was also able to create company-wide DLLs for creating process flow diagrams and plotting data points via line graphs. -
