Senior React Native developer delivering performant cross-platform mobile and web applications.
What I'm looking for
I am a Senior Software Developer specializing in React Native, ReactJS, TypeScript and full-stack mobile solutions, with a proven record of shipping enterprise-grade applications across finance, retail, and consulting. I drive performance improvements, streamline developer workflows, and lead cross-functional teams to deliver measurable business impact, such as digitizing retail operations across 100+ stores and reducing render cycles by 25%.
I mentor distributed engineering teams, create reusable libraries and tooling (including an open-source NPM package), and collaborate with product and business stakeholders to define KPIs and optimize user experiences. I continuously modernize codebases—migrating to TypeScript, introducing Redux and WebSocket optimizations—to improve reliability, scalability, and developer productivity.
