Impactful Solutions.
Software Engineer
I’m a Software Engineer with 8 years of experience across the full stack. I specialize in building fast, scalable systems using TypeScript (React/Next.js) on the front and Go or Laravel on the back.
Most of my career has been spent in Fintech and E-commerce. I’ve been in the trenches building institutional investment platforms for Bibit and managing complex, multi-brand e-commerce architectures for Central Mega Kencana. I’m comfortable working where performance and security are non-negotiable.
I don't just 'write code' to clear tickets—I build systems to drive change. Whether it's shipping a design system or optimizing a checkout flow, I care about the real-world impact of the software I build.
