Project history
Designed and implemented a full-stack AI-powered letter generation system for an insurance company, handling the entire architecture and development independently. The solution included a Vite + React + TypeScript frontend deployed on Vercel and a modular Node.js + Express backend hosted on Render.
Developed and maintained the project's API using AWS Lambda to build a microservices architecture with Node.js and Express. Expanded functionality across multiple APIs and enabled seamless integrations between modules using RESTful principles.
Developed and maintained two Angular frontends (admin and user-facing) with Tailwind CSS, integrating a Lumen-based BFF and Squidex CMS for dynamic content. KeyCloak handled authentication, while the role involved feature enhancements, bug fixes, and UI/UX improvements.
