In my independent software engineering practice, I build backend and mobile systems in C#/ASP.NET Core, Go, Python, and Flutter. I turn duplicate requests, concurrent writes, migrations, and dependency outages into explicit service behavior with regression coverage.
I built an inventory and work order API with retry-safe stock posting, append-only movements, and PostgreSQL migration and recovery checks. I also developed an auditable incident SLA ledger and a Go rate limiter, with concurrency tests and CI checks for recovery and failure cases.
