Systems Engineer and Senior Full Stack Developer with 11+ years of experience building business software for web and desktop environments using .NET Core, ASP.NET MVC, Entity Framework, React, and SQL Server. Strong background in transactional systems, internal enterprise platforms, reporting workflows, and operational software for sales, inventory, purchasing, finance, and permissions. Specialized in AI-assisted and agentic software development using Claude Code, Open Code, Codex, GitHub Copilot, Gentle AI (SDD), Gentle PI, and Antigravity CLI to accelerate delivery, improve iteration speed, and support implementation, debugging, refactoring, and code review.

One of my strongest case studies is the architecture and development of a full Point of Sale platform built through an agent-driven workflow with human technical direction, architectural control, and production-oriented validation.
