What I'm looking for

I'm looking to modernize enterprise systems, make architecture decisions, lead and mentor engineering teams, and contribute to AI integrations in collaborative remote environments.

I've modernized enterprise systems at Invent Software and BR GAAP Corporation, moving legacy desktop and Windows applications to scalable web platforms with ASP.NET Core, .NET 8, React.js, and JavaScript.

At BR GAAP, I migrated more than 100 automated financial reports with zero disruption to government clients and improved data retrieval and visual rendering times by 50% through dynamic data grids and filtering.

I build reliable backend and compliance-focused features, including REST APIs, audit logging with C# and Entity Framework, and automated test suites using NUnit and Moq. I also maintain stable delivery environments with Docker, Linux, Git, and GitLab CI/CD.

As a Tech Lead at Invent Software, I mentor three junior developers, guide Clean Architecture and SOLID practices, and serve as the engineering contact for enterprise accounts. I've also contributed to LLM training, data labeling, and AI-generated code and logic implementations in remote international teams.
