My Story
From Engineering to Building
The short version: I saw a real problem, learned the skills to solve it, and left my job to build the solution.
🎯 The Origin
Before entering the workforce, I ran a small dropshipping store.
Customer support by email quickly became a bottleneck.
Most emails were repetitive, but using templates alone was no longer enough.
The tools out there didn’t solve the problem — they were either too expensive, too generic, or disconnected from the real workflow.
🛠️ Learning by Doing
I studied Computer Science at UC3M, did an Erasmus in ML, and later a Master’s in AI.
At NTT DATA, I learned how large organizations operate:
consulting, data, and structured execution.
Then at Bankinter, I built RAG pipelines and AI agents used in real operations.
That’s where I understood what useful AI really means, and realized I wanted to build something bigger than a comfortable corporate path.
🚀 The Leap
While working at Bankinter, I started building Respondize on evenings and weekends.
When I saw real potential, I made a decision:
leave my job, move back home to Málaga, and go all-in on this opportunity.
The worst that could happen was to go back to the life I was already living.
🆕 Now
Today I’m living my dream, working 24/7 on a project I’ve built from scratch and fully committed to turning into a real company.
We already have our first users, and I’m focused on learning fast, improving the product, and solving the problem properly.
Being part of Wayra Telefónica’s incubator gave me access to other founders and a different way of thinking about how to build and take projects further.
Looking Ahead
What I Want to Build Long Term
Respondize is my first real product, but it's part of a bigger picture. I want to build integrations and automations deeply embedded in real business operations — not chatbots put together in a couple of weeks, but complete systems that change from the ground up how teams work.
I'm interested in growing as a founder in high-density environments where I can learn from people who've done it before. I believe the best way to build great technology is surrounded by people who demand excellence — and who build with purpose, empathizing with the problem. Not just with ambition.

sept. 2022 – feb. 2023
During this internship, I worked on building analytical dashboards and identifying key pain points for clients related to operational inefficiencies, recurring issues, and lost time. I analyzed their data, highlighted improvement opportunities, and prepared insights to help them optimize their processes and make better decisions.
Core Impact
