About Me

Biomedical Engineer turned AI Software Engineer. I spent four years at Mahidol University building signal-processing systems and competing on the international stage with BCI research — which taught me to care about systems that work under pressure, not just in demos. Today I design and ship agentic AI pipelines, RAG architectures, and the full-stack infrastructure that makes them actually usable.

Experience

  • Designed and executed comprehensive test plans for new features on the LINE MAN food delivery platform, covering boundary and edge cases including Figma UI validation, payment gateway flow (K-Bank Mock API), coupon issuance, and 15-minute session timeout.
  • Developed automated API tests in JavaScript using Postman to validate feature requests, data flow, and response integrity, and performed manual database validation checks in MongoDB to verify data consistency.
  • Documented all testing methodology and results in Confluence for team visibility and participated in the CI/CD delivery pipeline by logging verified issues with build versions into the deployment queue.

Projects

A full-stack project management platform with full CRUD for projects, tasks, and notes — built on Next.js App Router with React Server Components, Server Actions, and NextAuth v4 authentication. A separate async FastAPI service owns the AI pipeline: RAG-powered agentic chatbot with pgvector semantic search, a tool-calling loop up to 5 iterations, native thinking mode, and real-time multiplexed streaming surfacing generation metrics. The 4-service stack runs in Docker Compose with NVIDIA GPU passthrough, CI via GitHub Actions, and is deployed to projecthub.aphiwish.com through a Cloudflare-secured tunnel.
