I build backend systems for businesses whose infrastructure is one bad day from collapse. Python, FastAPI, APIs, automation, integrations — if it’s broken, I fix it. If it’s slow, I make it fast. If it’s held together by duct tape and hope, I turn it into something reliable. I specialize in API workflows, automation pipelines, data extraction, and AI‑assisted backend logic. Clean code, fast delivery, zero excuses.
