SANG CAO LABS

Hi,I'm Sang.

- Full-Stack & AI Engineer, Independent Product Builder.

I'm a full-stack engineer based in Ho Chi Minh City, with 10+ years building and maintaining web products across backend, frontend, cloud infrastructure, and applied AI.

I own engineering end to end — from requirements and system design through backend, frontend, deployment, and production support. My core background is PHP and Laravel platforms, modern React applications, Python services, AWS infrastructure, and the practical integration of language models into real products.

I add AI where it creates real leverage, not theatre: grounding, evaluation, failure handling, cost awareness, and clear limits around what the model should and should not decide.

When the path is unclear, I make it concrete. That's usually why I'm hired.

Current Focus

  • Building grounded AI support tools for real business workflows
  • Shipping NoLight and SideSpace from idea to the App Store
  • Writing practical guides from real product and engineering decisions
  • Available for high-ownership full-stack, backend and applied AI work
