Hi, I'm
Mobile & Web Frontend Engineer
I build mobile and web apps with React Native and Next.js — from first screen to store — and I harden them against crashes, attacks, and slow releases.
01 · What I solve
Four problems I solve every day — and the outcomes you can expect from working with me.
Problem: You need an iOS & Android app without doubling your team.
What I do: End-to-end React Native / Expo development — architecture, screens, native modules, store submission — including major version upgrades without breaking the product. I'm pretty flexible, I could do Flutter as well, but React Native is my daily driver.
Problem: Your app handles sensitive data and a breach is not an option.
What I do: Production-grade hardening: certificate pinning, jailbreak/root detection, biometrics, and hardware-backed secure storage.
Problem: Slow screens and crashes are costing you reviews and retention.
What I do: Performance monitoring, rigorous error handling, and a crash-free culture that keeps quality high as you scale.
Problem: Slow releases and inconsistent UI slow your roadmap down.
What I do: Optimized CI/CD, reusable design systems, and internal tooling that removes friction from the whole team.
