Full-Stack Developer · Web & Mobile

I build web platforms, mobile apps and the APIs that connect them — from accessible interfaces to payments, shipping integrations and automated delivery.

I'm a Computer Science undergraduate at UERN, building products with React and TypeScript, Node.js and Bun, C# / .NET, and React Native.

• Full-stack products: e-commerce, administrative dashboards and mobile apps published on the App Store and Google Play.
• Integrations & automation: payments, shipping, marketplace data and background workers.
• Performance & delivery: optimizing APIs and data flows, with Docker and CI/CD on Linux.
• Research & teaching: accessibility applications, ERP/marketplace integration and mentoring students in C programming.
