I build fast, reliable products across web and mobile.
Full-stack engineer working in React, Next.js, TypeScript, and Node — with 4+ years building production iOS apps in Swift and SwiftUI. Currently at Nawatech, Jakarta.
About
I'm a software engineer based in Jakarta, currently building web and mobile products at Nawatech. My core work today is in React, Next.js, and TypeScript — architecting frontend systems like a BFF-pattern ERP dashboard and a production halal-certification portal used by an accredited Indonesian institution. Before that, I spent several years as a dedicated iOS developer, shipping 10+ production Swift/SwiftUI apps including a hybrid native app for Astra Honda Motor, Indonesia's largest motorcycle manufacturer.
Outside client work, I build things that interest me: a multi-agent LLM system that debates its way to production-ready specs, an autonomous crypto trading bot with tiered LLM routing, and a privacy-first iOS vault with client-side AES-256 encryption. I have a B.Sc. in Informatics Engineering from UIN Syarif Hidayatullah, and was a Paragon Scholarship awardee (2021–2024), selected from 1,500+ candidates.
