About Me

With over 25 years building systems that work in production, I help startups, agencies and growing companies make technical decisions that save time, money and future headaches. I'm not a delivery resource: I'm the senior technical profile who designs the right architecture from the start, leads teams and ensures deployments don't break what's already working.

I've founded a SaaS, led technical teams and built critical systems for over 2,000 users across sectors like digital health, business management and music content distribution.

I integrate artificial intelligence practically into my current workflows and products: from using LLMs and code assistants to accelerate development, to building autonomous agents, code reviews and intelligent automations with models like OpenAI and Claude. I don't adopt AI as a trend, but as a real tool to multiply productivity and the efficiency of the systems being built.

I also collaborate with an NGO in the Raval (Braval) neighborhood in Barcelona, which focuses on promoting education, sports, combating marginalisation and exclusion of young immigrants.
