What I'm looking for

I'm looking to lead and improve scalable backend systems, reduce technical debt, mentor engineers, and deliver reliable products in dynamic remote environments.

I've built and modernized backend systems for Mengantar, Gak Gendut Lagi, and RevivaL TV, with a focus on reliability, scalability, and maintainable code.

At Mengantar, I refactored critical Node.js and Nuxt legacy modules, eliminated recurring production-critical failures, and improved performance by 80% across more than five core services.

At GGL App, I led the backend team through a v2 API rebuild in Laravel, achieving sub-500ms responses for 90% of endpoints and reducing production GCP resources by 40%. The platform generated more than $700K from 12K successful transactions over a year.

I also mentor engineers, review code, improve testing practices, and lead integrations across platforms using PHP, Node.js, PostgreSQL, Redis, Docker, Kubernetes, and GCP.
