What I'm looking for

I seek a technically challenging role building scalable full-stack systems, with strong engineering culture, CI/CD, testing, and opportunities to mentor and shape architecture.

I am a Full-Stack Software Developer with extensive experience building and maintaining enterprise-grade .NET applications and modern web applications using React and Next.js. I have delivered layered architectures, SDKs for modular API access, and microservices backends that improved maintainability and reduced defects.

My work spans freelance and in-house roles where I led integrations with government services, maintained mission-critical healthcare systems, and introduced DevOps practices including automated CI/CD, testing, and monitoring. I mentor junior developers and delivered team training that raised code quality and collaboration.

Notable projects include a full-stack solution for historical seed data management built with .NET Core, Blazor, EF Core and SQL Server, and Blueledger, an AI-powered expense tracker with real-time notifications, unit/integration testing, and comprehensive instrumentation and deployment pipelines.
