What I'm looking for

I'm looking to build secure, reliable backend and Web3 products where I can contribute to API development, scalable deployments, blockchain integrations, and meaningful user-facing systems.

I've built end-to-end backend systems for products including VibeCraft, an AI-powered creative suite, and HarmonyKloud, a U.S.-based healthcare platform serving 500+ users.

At TekAIDA Consulting, I independently designed, implemented, containerized, and deployed VibeCraft's backend using Node.js, Express, TypeScript, MongoDB, Docker Compose, and a VPS. I also authored a complete API reference covering authentication, projects, conversations, SSE streaming, and pagination.

At HarmonyKloud, I build and maintain APIs for patient data and appointment tracking, support integrations with Waystar and Office Ally, and strengthen authentication, data protection, testing, and deployment workflows.

I've also delivered Solidity smart contracts and Web3 projects including GNGN-token, SIMBI-AI Bot, CivicLink, and DojoPay. I enjoy building practical, secure systems—from REST APIs and healthcare workflows to decentralized identity, tokens, and on-chain payments.
