Full-Stack Engineer Building AI-Driven Systems

Full-stack engineer focused on backend-heavy products and agentic workflows. I build reliable systems end to end, from APIs and orchestration layers to user-facing interfaces. Currently pursuing an MSc in Computer Science at TU Delft after internships in research (LaBRI) and startup engineering (Packmind).
