Senior Software Architect | Full-Stack Engineer | Protocol Engineer | Open Source Enthusiast

• 🌱 Started building for the web at 12 — now 14+ years into distributed systems, IoT platforms, and real-time infrastructure.
• 🏗️ Design end-to-end architectures, from embedded device communication to scalable cloud backends.
• 🕸️ Deep experience in protocol engineering — TLS, MQTT, WebSocket, WebRTC, SOCKS4/5, P2P networking.
• 🤖 Actively use AI tools (Claude, Gemini, ChatGPT) to accelerate development and sharpen architectural decisions.
• 🔓 Reverse engineer and open-source enthusiast at heart.

Senior Software Architect @ Perfumatic Group BCN (2024–2026) Owned end-to-end architecture of an IoT platform for perfume vending machines — Node.js/TypeScript backend, an MQTT+Protobuf comms layer for real-time telemetry, and ReBAC access control via OpenFGA. Cut dev & maintenance costs by 50–75%.

Senior Full-Stack Developer & Tech Lead @ Bastyon (2022–2024) Led a 4-person frontend team on an open-source blockchain social platform. Built client-side video transcoding (FFmpeg) and Tor-based P2P routing inside an Electron desktop app.

Founder & Engineer @ Reyuno (2020–2022) Architected a zero-trust fintech platform that keeps all sensitive banking data entirely client-side.

Founder & Full-Stack Developer — Self-employed (2012–2020) Built Inzerto, Framox, and a decentralized media-authenticity system on Filecoin/IPFS — mostly by reverse-engineering private APIs.
