I build AI agent systems, RAG pipelines, and full-stack applications with Go, TypeScript, and Python.

I've built SiamRouter AI, an end-to-end AI agent and RAG pipeline using Next.js, Go, PostgreSQL, and pgvector to retrieve support context and generate auto-resolution drafts.

I implemented Gemini function-calling workflows for database mutations and incident alerts, plus a fault-tolerant Go routing engine with retries, Dockerized microservices, CI/CD, and Render deployment. Previously at Bluebik Group, I developed a traffic-management prototype and co-built a Python/OpenCV solution that increased intersection vehicle throughput by 97%.

I've also built cross-platform mobile applications with Kotlin Multiplatform and Swift, integrated Firebase OCR and real-time synchronization, and mentored more than 50 students in software development, data structures, and algorithms.
