Profile
Full-stack engineer with a focus on applied AI. I build complete product systems end to end: a Laravel trading-analytics SaaS with a custom analytics engine, native MQL4/MQL5 desktop software, and an LLM-driven content platform. Comfortable across backend, frontend, data, and the integrations between.
