I'm a Full-Stack Software Engineer and M.Sc. Cybersecurity candidate 🔐 based in Lisbon 🇵🇹. I build production web platforms with Next.js, TypeScript, and Python — and ship games on the side with Unity ECS. Currently extending my full-stack background into security engineering through my M.Sc. at Politécnico da Guarda, with hands-on research in AI-driven network defense and post-quantum cryptography.
