• Dev: Scalable web apps (Vue.js, TS) & Node.js optimization. • Test: Validated effectiveness via mutation testing (StrykerJS). • Code Quality: Resolved SonarQube hotspots & smells. • Sec. Champion: Bridged Eng/Sec teams to align requirements. • Sec. Verify: DAST/SAST (Burp, Invicti) & OWASP ASVS checks. • CI: Automated unit tests via GitHub Actions. • AI: Developed prompts for automated test generation.

Developed a scalable web platform using React and MongoDB, featuring responsive design and intuitive features. Used GitLab for issue tracking to organize the development process and ensure timely delivery.

Extended the scope of my bachelor thesis by continuously working with the research team to implement the theoretical concepts. I was responsible for the technical execution and developed a decentralized access control prototype. Tech Stack: React, Solidity (Smart Contracts), Remix IDE, GitHub.

I graduated with a final grade of 8.28/10 and selected the elective module "Computer Systems Security" (Network Security, Cryptography). My bachelor’s thesis was titled "Leveraging blockchain to develop an access control system".
