Petersen
Software engineer · Applied AI & full-stack systems
Profile
Software engineer with an MSc in Computer Science, focused on applied AI, reliable data systems, and end-to-end product delivery. My thesis, graded 12/A, combined reinforcement learning with deterministic simulation, reproducible experiments, and evaluation tooling. I bring practical experience delivering user-facing systems with Python, TypeScript, React, SQL, and cloud backends.
Core strengths
Applied AI
Python, PyTorch, Stable-Baselines3, model training, evaluation, experiment design, and debugging.
Full-stack delivery
Requirements, data modeling, APIs, React, React Native, deployment, and handover.
Engineering quality
Testing, validation, logging, CI, stable interfaces, and security-aware development.
