Work Experience
Guest Professor
ESTG — Polytechnic Institute of Viana do Castelo (IPVC)
- Taught Advanced OOP at ESTG (organizational learning theme: AI and computer vision) within the computer engineering program.
- Taught software engineering with Scrum/Agile methodologies, version control, and collaborative development workflows.
- Taught artificial intelligence and object-oriented programming across multiple programs (Eng. Informática, Mecatrónica, Computação Gráfica e Multimédia).
- Supervised the end-to-end project module; students delivered full-cycle applications from architecture through deployment.
- Brought 15+ years of shipped industry work directly into ESTG classrooms, connecting students to the cooperative engineering ecosystem in Viana do Castelo.
Visiting Lecturer
University of Porto
- Taught Operating Systems (S1 2025/26) within the Department of Informatics Engineering (DEI) at FEUP, Portugal's top-ranked engineering faculty.
- Taught Parallel & Distributed Computing (S2 2025/26) — directly aligned with my PhD research.
- Translated 15+ years of production engineering experience into a system-level CS curriculum grounded in real distributed systems.
Founder | CEO
Xarp (XARP Reality Labs)
- Founded XARP Reality Labs, a Portuguese physical-AI startup, with three commercial threads: Dressify (smart-mirror retail), museum interactive installations, and brand activations.
- Shipped Dressify smart-mirror hardware into physical retail — a computer-vision and AR pipeline running on in-store devices, as well as a behavioral analytics layer surfacing engagement data to retail clients.
- Built partnerships with Portugal's leading R&D institute (INESC TEC), the country's largest retail group (Sonae), and its flagship deep-tech accelerator (Unicorn Factory Lisbon). This was EU-funded.
Founder | President
CTVC – Cooperativa Tecnológica de Viana do Castelo
- Founded Portugal's first technology cooperative. Built the legal structure, governance model, and operating practices from scratch. CTVC is listed on the EU Transparency Register and acts as a tech-innovation center.
- Led EU-funded project portfolio across distributed marine sensing (Aquascan AI, OMAE 2026), energy-community platforms (CoopEnergy), and membership-org SaaS (SIGO).
- Built a "mentors mentoring mentors" culture that converted apprenticeship members and student internships into recurring engagements and standalone businesses.
- Served as Chair of the Supervisory Board (2025–Present) after founding the cooperative and serving as Founding President of the General Assembly (2021–2025).
Unity Tech Lead
Jawaker FZ LLC
- Conducted in-depth technical sessions with Unity developers, enabling independent critical thinking and reducing reliance on rigid patterns.
- Improved code quality and coverage by fostering a mindset shift toward problem-solving over convention-following.
- Introduced a data-driven performance improvement framework using version control history, static analysis, and profiling.
- Accelerated the development cycle by optimizing team workflows and communication.
Co-founder | CTO
FYX Gaming
- Co-founded a venture-backed blockchain-gaming company that raised $6+ million and grew to 15+ engineers and artists at peak.
- Led architecture and programming end-to-end across CryptoFights, the FYX Gateway marketplace, and Kronoverse infrastructure. Owned release management and CI/CD across the company's lifetime.
- Hand-rolled a Bitcoin SV (BSV) wallet stack in C#/Unity, plus an on-chain settlement layer. The platform set BSV transaction-volume records during the BSV peak.
- Authored the technical white paper, in-game economy design, and the low-level client-side wallet software. Designed and shipped the on-chain digital asset (NFT) layer.
Lead Programmer | Release Manager
Soluna Labs
- Developed and published Hit n' Run, a mobile game that reached hundreds of thousands of users and was featured on the App Store.
- Collaborated with a product owner from a leading company in the advertising space to leverage multiple ad networks and analytics and maximize returns.
- Contributed to the game design. Established the main game loop and implemented procedurally generated objectives.
- Analyzed features and funnels after launching them and conducted A/B testing.
Unity C# Programmer
Repertoire
- Built and published a classical-music mobile game (Repertoire) in partnership with Ien Cheng, a former Google product owner. Worked across audio interaction design and shader programming.
- Adopted the product management methodology learned from a former Google PO — iterative shipping, audio feature prototyping, and tight feedback loops with the music-education domain.
- Delved into shader programming and music generation.
Project Manager | Lead Unity 3D C# Developer
uTappz Mobile Development
- Shipped almost 200 iOS games as the sole developer over roughly three years, working with a rotating roster of around 6–7 art-only contractors.
- Built a reskinning pipeline (CI/CD before it was the default conversation in mobile-game shops) and hand-rolled dynamic ad-network mediation logic.
- Owned the App Store Optimization (ASO) release strategy — keyword targeting and category placement drove the studio's discoverability.
- Trained and coordinated a distributed team of artists across time zones; handled the entire engineering, release, and monetization stack solo.
Unity C# Developer
Freelance
- Started my own business as an independent contractor.
- Worked with several clients, with varied and increasing responsibilities and complexity of projects.
- Worked on diverse products, from game prototypes to simulations.
