What I'm looking for

I’m looking to lead iOS and React Native delivery using New Architecture performance work, mentoring cross-functional teams, and AI-assisted engineering to improve velocity, quality, and maintainability.

I’m an “Accomplished Technical Lead” with “13+ years of experience in mobile and web engineering,” focused on building scalable, high-performance products. I specialize in “React Native 0.76+” using the “New Architecture (Fabric, TurboModules, JSI)” to remove bridge latency and improve UI responsiveness.

Across “25+ apps,” I deliver with a strong iOS foundation in “Swift and Objective-C,” and I lead teams with AI-assisted workflows (Cursor AI and ChatGPT) to “optimize team velocity and code quality.” Recently, at Blockgemini, I reduced debugging time by “25%” through Cursor AI integration and modular architecture, and at GoMedii I scaled the ecosystem to support “10,000+ international patients” with high-security standards.
