About Me
More about my journey →
Code with purpose, design with intent.
I started writing my first lines of code in 2019 and never stopped. Today I help startups and companies turn rough ideas into production-grade products — thinking in systems, shipping in iterations.
My sweet spot is the full stack: pixel-perfect front-ends, resilient back-ends, and the DevOps glue that keeps everything running while the team sleeps.
— Vylonium, Jakarta 🇮🇩
"Vylonium rebuilt our entire platform in three months. Page loads dropped from 4 seconds to under one, and conversions went up 34%. He is the rare engineer who genuinely cares about business outcomes."
Daniel Pratama — CEO, TokoKilat

What I Do
Full-stack services, one accountable partner.
No hand-offs between agencies. One person who owns the whole stack — and the result.

From MVP to enterprise: React / Next.js front-ends backed by Node.js or Python services, with clean APIs and boring, dependable infrastructure.
02
Mobile Apps (iOS & Android)
Cross-platform Flutter apps that feel native, ship fast, and keep store ratings above 4.5.
03
API & Backend Engineering
REST and GraphQL APIs, database design, queueing, and integrations — built to survive 10× growth.
