Profile
AI-focused engineer who maps where automation and AI agents create real value across a business, then builds and ships the system myself. Backed by full-stack depth: 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.
