What I'm looking for

I’m looking for a role where I can own frontend architecture end-to-end, build high-impact products with React/React Native, and strengthen design systems, CI/CD, quality, and performance—ideally within Web3 or transaction-based platforms.

I’m a Senior Frontend Engineer with strong experience building scalable web, mobile, and cross-platform products—from architecture to deployment. I’ve worked on customer-facing apps, internal tools, marketplace platforms, SaaS, mobile apps, design systems, and complex transaction-based products.

Most recently, I built Meteor Wallet v2 across Android, iOS, web, and browser extension from a single React Native codebase. I delivered transaction-based flows (authentication, signing, on-chain data decoding, integrations, and monitoring) and core capabilities like passkey-based authentication, WalletConnect, Ledger integration, and third-party integrations, while maintaining and improving MyNearWallet.

Earlier roles strengthened my end-to-end delivery and performance mindset: I integrated major Indonesian marketplaces into an omnichannel commerce platform, optimizing CI/CD to reduce deployment time by over 50%, and contributed to QA automation. I’ve also migrated a monolithic Ruby on Rails system into microservices, built React and React Native apps, created a company-wide design system and internal UI component library, and was awarded Top Performer of the Year twice.
