At Poyesis, I own end-to-end delivery of production web and mobile applications, from technical planning and architecture through deployment and iteration. I’ve contributed to the successful delivery of 8+ client-facing applications.

For Lucen Capital, I built real-time market experiences using Hyperliquid WebSocket and API data, and contributed to shared market-state architecture and wallet-connected trading flows. I also contributed to production mobile functionality across the React Native stack.

As a freelance Full Stack Developer, I deliver projects from requirements and technical planning through handoff and post-launch support. I’ve also developed user-facing features for an AI-powered learning platform, including AI-assisted study notes and quizzes.
