About me

Profile

I've spent the last 4+ years at Techo Startup Center building production systems for government and enterprise projects using Node.js, Spring Boot, React, and Next.js. I've also worked on blockchain, deploying smart contracts on Hyperledger Besu and integrating Singapore's Open Attestation framework. On the DevOps side, I've set up Kubernetes clusters and CI/CD pipelines with Jenkins, GitHub Actions, and Argo CD. Outside of my day-to-day work, I teach full-stack and backend development at Wing Bank and Sunrise Institute. Right now, I'm getting into LLM tooling, MCP, and data engineering.
