I'm Alex, a 32-year-old backend developer based in Barcelona. I've spent years building APIs and systems with .NET, and lately I've been diving deep into two worlds that have completely taken over my spare time: cybersecurity and AI.

I approach tech with a security-first mindset — got my Google Cybersecurity cert and SC-900 under the belt, currently working toward Security+. On the AI side, I'm all about self-hosted models, local LLMs with Ollama, and building agents that actually do something useful.

I'm a big believer in FOSS and self-hosting. If something can run on my own hardware instead of someone else's cloud, that's where it lives.

When I'm not at the keyboard: NewJeans on the speakers, learning Rust on the side, and probably breaking something I just fixed.

Backend & APIs: ASP.NET Core · Minimal APIs · FastAPI
AI / LLMs: Ollama · MCP · RAG · local agents
Databases: SQL Server · SQLite · PostgreSQL
Infra: Docker · Azure · Cloudflare Tunnels · self-hosted

• 🦀 Rust — slowly, painfully, worth it
• 🔐 Security+ — turning curiosity into a cert
• 🤖 AI Agents — local models, RAG, automation that doesn't phone home
• 📦 Self-hosting — because I like owning my data
