About Me

Full Stack Engineer working on agentic AI, developer tooling, and AWS serverless architecture

Simon Cheam
Full Stack Engineer | Agentic AI & Developer Tooling

I build AI-enhanced web applications and the developer tooling around them — TypeScript, React, and Next.js on the front, AWS serverless on the back, with agentic systems doing the work in between. Recent work has centred on codifying agentic-engineering practice for enterprise teams: shared Claude Code commands, skills, and plugins, plus headless orchestration that automates multi-step development workflows.

A background in mechanical engineering and a stint founding a D2C product line shape how I work: I care about what a system costs to run and whether it actually ships. This site is an example — its RAG backend was rebuilt from a managed Bedrock Knowledge Base into a hand-built pipeline after $29.43 of charges in roughly 61 hours exposed a projected ~$350/month run rate, avoiding about $4,200/year.
