If your system got slower over time and nobody really knows why — that’s usually where I come in. Most developers avoid messy data, slow queries, and systems nobody wants to touch. That’s where I do my best work. My core is .NET and SQL. Not just writing queries, but understanding why things break when data grows, and fixing it without turning everything upside down. What I work with: • C# / .NET — data processing, automation, background services, desktop tools • SQL (deep) — complex queries, performance tuning, execution plans, large datasets • APIs & backend — REST, Node.js, Linux deployments • Automation — Selenium, scraping, data pipelines, legacy integrations • Infrastructure — Docker, Linux, FastAPI, PostgREST, full stack setup • Frontend — AG Grid, WordPress customization I also use AI in real work — tools like Claude and AI agents help me move faster, understand unfamiliar stacks, and scale solutions without slowing down. So if your project runs on something new — that’s not a blocker. I’ve worked with old and undocumented systems too — where you don’t have docs, only behavior. If you already tried the obvious fixes and they didn’t work — that’s usually when I get involved. I don’t need long explanations. I read the system, find the real issue, and fix that. I won’t promise miracles. But I will tell you exactly what’s wrong and what it takes to fix it.
