About

I build production systems that stay reliable when the stakes are real.

Platform Engineer with expertise in building enterprise-grade payment systems, cloud infrastructure, and scalable applications. Passionate about security, performance, and developer experience.

My work sits where backend engineering, infrastructure, and product delivery overlap. I care about resilient architecture, clean operational behavior, and shipping systems that still make sense six months later.

Founder & Solo Engineer

SolveMY

Malaysia (Remote)

Solo-architected and solo-built a two-sided service marketplace for Malaysia, connecting homeowners with vetted service providers. Built the entire platform end-to-end: Go backend, Flutter mobile app, and Next.js web portal, with PostGIS spatial matching, iPay88 payments, and a full escrow + double-entry ledger engine.

What I Do

The areas I keep returning to across products, platforms, and teams.

Build enterprise payment systems with Type Approval and APIP compliance

Design secure microservices with JWT, HMAC-SHA256, and AES-256-GCM encryption

Deploy and maintain production Kubernetes clusters with 99.9% uptime

Optimize SQL queries achieving up to 95% performance improvements

Architect cloud-native solutions on AWS and Tencent Cloud

Develop modern web applications with Next.js, React, and TypeScript

How I Work

I prefer systems thinking over surface polish.

Design for the whole system

I am usually thinking past the feature itself: contracts, failure modes, operational visibility, and how the next engineer will extend the system without fighting it.

Reliability is part of the feature

Payments, infra, and internal platforms only work when edge cases are handled deliberately. I prioritize correctness, observability, and safe operational behavior from the start.

Ship with urgency, not chaos

I move quickly, but I do not treat speed as an excuse for unclear architecture. The goal is delivery that stays maintainable after launch, not demo-quality momentum.

Work Experience

A track record across payments, platforms, and high-traffic production work.
