01 — about

My latest experience is with a financial technology company, where I architected and developed real-time, scalable web systems and internal portals for secure asset valuation and management. I now lead full-stack work across product teams, building Firebase applications end to end and Next.js front ends on FastAPI services, backed by Google Cloud for API integrations, service accounts, and containerized deployments. My scope has also grown into Agentic AI / AI Agents, powering data annotation and data crawling workflows.

At CLSU, I led the development of institution-wide platforms and taught programming, bridging technical solutions with real user needs.
