Need a React Native app shipped to both stores, a reliable MERN backend, or an AI feature added to an existing product? I build and improve production mobile and web products from architecture and APIs through deployment, monitoring, and support. I’m a senior React Native and full-stack developer with 9+ years of experience delivering real products for iOS, Android, and the web. At Goally, I developed multiple production React Native applications available on both app stores and built the complete backend using Node.js, Express, and MongoDB. Previously at Intagleo Systems, I led React Native development across Pynwheel’s mobile application portfolio. My work there was primarily focused on mobile architecture, feature delivery, API integrations, performance, releases, and production support. I also contributed to separate MERN-stack projects for other Intagleo clients. Selected results: • Improved React Native load performance by 40% • Improved time-to-interactive by 1.8 seconds • Reduced analytics computation time by 37% • Helped reduce crashes by approximately 50% on an app-modernization engagement • Led and mentored a four-engineer development team I can help you with: • Production React Native and Expo apps for iOS and Android • React Native MVP development from requirements or Figma • Existing app rescue, debugging, upgrades, and modernization • Performance optimization and crash reduction • Node.js, Express, MongoDB, and MERN backend development • REST and GraphQL API development and integration • AI-enabled mobile and web features • AI evaluation and product workflows using React and Node.js • Native iOS and Android integrations • App Store and Google Play submission • Automated testing, CI/CD, monitoring, and production support Core stack: React Native, TypeScript, JavaScript, React, Next.js, Node.js, Express, MongoDB, Redux Toolkit, MobX, REST APIs, GraphQL, Firebase, AWS Amplify, Jest, Fastlane, and GitHub Actions. I work best with startup founders, product companies, and development teams that need a senior hands-on engineer—not someone who only implements screens. I can work across mobile architecture, backend services, integrations, deployment, and the production issues that appear after launch. Send me your requirements, Figma designs, existing application, or current technical bottleneck. I’ll identify the main risks, recommend a practical first milestone, and explain how I would approach delivery.
