I'm Fernando Medina, a full-stack and infrastructure engineer based in Tijuana, Baja California. I've spent 3 years at Enteracloud and 6 months at Purple AI, building web applications (Laravel, Vue, FastAPI) and applied AI systems, and running the infrastructure behind them (Kubernetes, Proxmox, CI/CD). I focus on taking AI to production: Whisper transcription, local models, embeddings and agents. I also build sports prediction models (NFL, in development).
