I’m a React Native developer with hands-on experience architecting and shipping cross-platform mobile applications using Expo, TypeScript, and REST APIs. I build scalable, component-based apps with clear separation of concerns and efficient state management, so features land production-ready with minimal supervision.

At Rach.Finance (Remote), I worked across two platforms—a P2P crypto trading app and an enterprise payments API—end to end, from component design to final delivery. My work helped push user engagement up by 30%, and I tightened frontend security with input validation, CSP headers, and dependency checks, bringing frontend vulnerabilities down by 15% in audits.

I also improved performance and discoverability by tackling Core Web Vitals issues (reducing render-blocking, optimizing lazy loading, and cleaning SEO metadata) and maintained consistent test coverage at 95% to make releases more predictable and cut delivery time by 25%. In mobile projects, I’ve designed full app architectures from scratch (including payment flows with Alatpay) and delivered Android features independently without breaking existing functionality.
