I've built multi-tenant backend platforms at JF Knowledge Center and production marketplace workflows at Suank, using Node.js, PostgreSQL, Redis, JWT authentication, and AWS S3. My work includes a snapshot-based deployment engine for instant subdomain rendering and fixes for 15+ critical marketplace bugs.
I also built ArchFlow, a multi-stage AI system for automated software architecture generation, with FastAPI, LLM workflows, WebSockets, and dependency-aware recomputation. Across projects and open source, I focus on reliable APIs, efficient data flows, and scalable full-stack systems.
