Building systems that are smart, secure and fun.
I've been writing code since I was 14. What started as curiosity became a degree in Computer Engineering at ISCTE (2018–2021) and a Master's in Computer Science and Engineering at Instituto Superior Técnico (2021–2023), specialising in cyber security and artificial intelligence.
Today I work as a senior software engineer and independent consultant, fully remote from Lisbon. I've led engineering teams at global companies, hardened game backends, built AI vision and recommendation systems, and shipped everything from quick prototypes to production platforms.
I'm not looking for a job. I'm looking for interesting problems: a product that needs to exist, a system that needs securing, a process that should be automated. Small business or startup, if you need it built well and fast, we should talk.
Outside client work I run Pixy, an independent game studio making tactile little puzzle games for your pocket. It keeps me honest about craft, performance and what it takes to delight a player in the first ten seconds.

Three disciplines, one engineer.
Most teams need a builder, an AI specialist and a security lead. I bring all three to the table, which means fewer hand-offs and systems that are designed as a whole.
Software Engineering
End-to-end product engineering: architecture, APIs, cloud infrastructure and front-ends built to scale and to last.
- Distributed systems & API design
- TypeScript, Node.js, React & Next.js
- Cloud-native infrastructure & CI/CD
- Performance, observability & DX
Artificial Intelligence
From LLM-powered features to autonomous agents: practical AI that ships, evaluated rigorously and grounded in real data.
- LLM integration, RAG & agentic workflows
- Computer vision & recommendation systems
- MCP servers, tooling & evaluation pipelines
- Responsible AI, guardrails & safety
Cyber Security
Security as an engineering discipline: threat modelling, hardening and secure-by-design systems that stand up to real adversaries.
- Security assessments & penetration testing
- Threat modelling & secure architecture
- Application security & code review
- Identity, auth & zero-trust patterns
Whatever needs building, securing or automating.
I don't sell a fixed menu. These are the things clients ask me for most, but if your problem sits somewhere between them, that's usually where I do my best work.
Custom software & websites
From a fast, well-built website for a small business to full web platforms, APIs and dashboards.
Security assessments & penetration testing
Find the weaknesses before someone else does: app and API pentests, code review, hardening and a clear, prioritised report.
AI features & agents
LLM-powered features, computer vision, recommendation systems and agents that are evaluated, safe and actually useful.
Automation & integrations
Workflows, internal tools, MCP servers and integrations that remove manual work and connect your systems.
Backend hardening & architecture
Secure-by-design backends for games and products: auth, anti-cheat and abuse controls, scaling and observability.
Prototypes & MVPs
Validate an idea quickly with a working prototype, then grow it into a product without throwing it away.
Pixy — Small games. Big obsessions.
Pixy is my independent game studio, based in Portugal. We make tactile little puzzles for your pocket: games you can open for a minute and end up playing for a month. No timers, no lives to wait on. Explainable in one sentence, unfinishable in one sitting.

Eight by eight. No timer. No mercy.
The same eight by eight, in full colour.
Three in a row, and one opponent you cannot beat.
One frog per row, per column, per pond.
Minesweeper that never makes you guess.
Match the pair. Collect the picture packs.
Three lives, one hammer, and moles that never stop.
Stop the hand. Don't touch the line.
A logic puzzle about where the suspects stand.
Thread the pipes. Don't blink.
Let's build something together.
Whether it's a website that needs to exist, a security assessment before launch, or an AI feature that has to be trustworthy, I'd love to hear about it.
