Top-down shooter built in Unity's ECS/DOTS stack — also my B.Sc. graduation project. Data-oriented enemy AI, parallel jobs across the entity world, holds 300+ FPS with thousands of entities on screen.

The lab.
Smaller bets, sharp scopes.

Side projects and learning experiments where I try a stack or technique on a small, shippable target. Tokenized financing infra, a Pomodoro app, an ML classification pipeline. Each row links to the live build or source.

// cybersecurity track

Engineering software that survives contact with adversaries.

Currently pursuing an M.Sc. in Cybersecurity at Politécnico da Guarda, focused on Application Security & Secure Software Architecture. I treat security as an engineering discipline — threat modelling, secure-by-default design, and auditable cryptographic primitives baked in before the first commit.

Recent work: an AI-driven anomaly detection firewall for IoT that auto-revokes compromised devices on-chain (97.75% accuracy), and a teaching quantum-security operational platform with BB84/E91 QKD demos and a post-quantum crypto explorer (Kyber, Dilithium).

Four roles. Four stacks.
One throughline — ship it.

System spec sheet.

Everything I reach for first. Comfortable across the stack — strongest on the TypeScript + Python ends, with a Unity past that taught me to think in frames per second.

The operator behind the runtime.

Originally from Turkey. Came to Lisbon for an Erasmus exchange in 2024, stayed for the M.Sc., and now I ship production software here as a full-time engineer.

Outside the keyboard there's basketball, a few unfinished Unity prototypes, and the running joke that I'll learn Portuguese next semester.
