Full-Stack & Mobile Software Engineer building production applications with React Native, TypeScript, React, Node.js, and Swift.
🌐 Website · 💼 LinkedIn ·
I’m a full-stack software engineer with 8+ years of development experience, with a strong focus on mobile and cross-platform product development.
I build production applications across iOS, Android, and web, with experience in mobile architecture, APIs, authentication, real-time systems, offline-first data, BLE/IoT integrations, and cloud infrastructure.
I enjoy taking products from idea to production, rapidly iterating on features, solving difficult technical problems, and building software people actually use.
