Ángel Valera
Now: Senior Full Stack Developer / AI Specialist at Omada
I build web and mobile products end to end: from backend and infrastructure to the interface, and since 2024 with artificial intelligence too. I have been a developer, a CTO and a head of production. Away from the keyboard: music, films and a bit of magic.

01
What I do
Web & backend
SaaS, CRMs, marketplaces and public APIs in C#/.NET, PHP, Python, React and Node. Plus the infrastructure (AWS, Vercel, LAMP) to ship them.
Technical leadership
Almost ten years as CTO, head of production and R&D, and Scrum Master: choosing the stack, growing the team and translating what the client needs.
AI & data
Specialist in Artificial Intelligence and Big Data (600 h, top grade). Summaries with language models, MCP servers and products already using it in production.
What I enjoy most about this job is switching challenges: one day a medical app, the next a marketplace, then a civic site with the votes of the Spanish Congress. What never changes is the method: understand the problem, pick the right tool and ship it.

Who I am
I was born in 1981, I live in Alicante and I've been surrounded by keyboards and screens for as long as I can remember. But I'm not only a developer: I'm also the father of a wonderful girl called Eva, with whom I share cinema, music and magic. Magic goes way back: I am an amateur, not a magician, but I founded and ran Alicante Mágico, a national close-up magic convention, from 2008 to 2011, and chaired the Círculo Alicantino de Ilusionistas.
