My School and Work Projects
Bachelor's Thesis — Decomposition of a Monolithic Information System
This bachelor's thesis analyzes a monolithic information system with modular business logic to select a suitable module for decomposition and transform it into an independently deployable microservice. The new service is integrated back into the original system over REST, with JWT-secured user verification. The result is a fully functional eDocuments microservice, improving the system's flexibility, scalability, and extensibility, and laying the foundation for further decomposition.
Prague Office Menu App

Multi-office support secured per office. Built with Next.js 16, React 19, Tailwind 4, Vercel Blob, Upstash Redis, Leaflet maps, and GitHub Actions/Vercel cron jobs.
