About

Engineering focus grounded in production reality.

I work best on products where reliability, maintainability, and execution quality matter as much as raw feature output.

Software engineer focused on backend and full-stack delivery, with experience building SaaS platforms, internal systems, and customer-facing products for teams across the United States, Singapore, and Indonesia.

My work spans system design, API integrations, distributed services, infrastructure, CI/CD, and product implementation. I am most effective in environments that need pragmatic engineering decisions, stable execution, and clean delivery from architecture through production.

Current emphasis Backend systems, service design, and product delivery

Services

What I can help with.

Useful if you need a senior engineer who can own technical decisions, implementation details, and delivery quality without unnecessary ceremony.

Backend architecture and APIs

Designing and implementing reliable services, integrations, data models, and operationally sound production systems.

Full-stack product delivery

Shipping complete features across backend, frontend, and deployment with a bias toward maintainability and execution speed.

System modernization

Incrementally moving legacy systems toward cleaner boundaries, service decomposition, and stronger delivery workflows.

Infrastructure and release workflows

Improving deployment pipelines, containerized environments, runtime stability, and team confidence in production.

Contact

Open to backend, full-stack, and platform-focused work.

If you need help building, stabilizing, or modernizing a product, I am happy to discuss scope, constraints, and the most practical path forward.

The best fit is work involving APIs, service architecture, SaaS platforms, distributed systems, or production improvements where strong implementation discipline matters.
