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

01

Applied AI

Python, PyTorch, Stable-Baselines3, model training, evaluation, experiment design, and debugging.

02

Full-stack delivery

Requirements, data modeling, APIs, React, React Native, deployment, and handover.

03

Engineering quality

Testing, validation, logging, CI, stable interfaces, and security-aware development.
