My Story

My passion for programming started in high school when I discovered Scratch. Seeing how simple instructions came to life and created something functional fascinated me from the very first moment.

With over 3 years of professional experience as a Full Stack Developer, I've delivered e-commerce, multi-tenant SaaS, conversational AI (RAG, LangChain, real-time voice) and blockchain at Nanonino SL (Alicante) and Evvant SL. Core stack: React, Next.js, Node.js, TypeScript, Python/FastAPI, PostgreSQL/Supabase. What drives me isn't the tech itself, but the real impact on end users.

What Drives Me

What I'm most passionate about is building products people actually use: Talkrev (multi-tenant conversational AI SaaS with chat, voice & RAG) and PartsNow.ai (agentic commerce 50k+ parts, search by chat/voice/photo/VIN). I don't settle for "it works" technically; I aim for measurable impact on users and business.

Every time I see end users interact with an application I built and get positive feedback from the team, I know I'm on the right track. My goal: solve real problems with clean, tested, well-documented code. Experience in international teams (India, Spain) and agile methodologies.

🏃‍♂️ Outside of Code

  • •Passionate about padel - nothing better than disconnecting on the court
  • •Amateur runner - currently training for several races
  • •The discipline of running helps me keep a clear mind for solving complex problems
