Software developer training at 42 Porto, qualified programming technician through IEFP. I work close to the machine — C, Python, SQL and Linux — and I like the problems where the difficulty is in the system, not in the CRUD: concurrency, schedulers, graphs, constrained generation.
Three projects shipped to production, as full-stack developer and coordinating development. Based in Porto, Portugal.
◈ Codexion — concurrency in C
Worker threads competing for shared resources, coordinated with pthread mutexes and condition
variables. FIFO and EDF schedulers, deadlock prevention through all-or-nothing resource
acquisition, and a monitor thread that detects stalls past a time limit. Built and checked under
ThreadSanitizer.

◈ call_me_maybe — structured output from LLMs
A Python SDK for talking to language models and getting back schema-valid output, with function calling on top. Constrained decoding applied to a small 0.6B-parameter model, where there is no room to rely on the model behaving.

◈ azul — full-stack app, in production
A mobile-first reading journal: sagas, books, and annotations for characters, places, objects and
vocabulary, all cross-referenced through @mentions. React + Vite frontend against a
Django REST API, deployed on my own VPS behind Nginx.

◈ fly-in — routing over a graph
Drone routing simulator: given a map of connected zones with capacity limits and entry costs, it
moves every drone from the origin hub to the destination in as few turns as possible, with all
drones advancing simultaneously. Pure Python, fully object-oriented, no external graph libraries,
flake8 and mypy --strict clean.

◈ a-maz-ing — maze generation and visualization
Procedural maze generator with DFS and Wilson's algorithm, rendered in an interactive window.
The generation core is a standalone, reusable Python package. Every maze hides a 42 pattern in
its walls.

◈ Python-Modules — the 42 Python Piscine
All 11 modules: OOP, exceptions, data structures, file I/O, packaging, design patterns, Pydantic validation and functional programming.
