Summary

AI engineer and full-stack developer building AI products that reach production. I design and deliver pragmatic systems that improve productivity: RAG-backed chat apps, multi-agent AI platforms, analytics/reporting SaaS, API integrations, and data pipelines. Comfortable owning features end to end across Next.js and Fastify backends, React frontends, and Postgres/MySQL data layers. Experienced integrating third-party APIs (OpenAI, Grok, Stripe, PayMongo, Facebook, Slack, Telegram, AssemblyAI) and shipping to VPS/Fly.io with CI/CD. In 2026 I founded Codasc, my own software studio and app suite, where I design and build multi-tenant products end to end.
