Hi, I'm Néstor 👋

Technical Leader · AI Engineer · Travel Tech

I build technology that frees people from work that adds no value to their lives. For 9 years I was CTO & Co-founder of Aervio, a B2B travel tech startup where I built the product from scratch — and where I learned that the best tech decisions come from understanding the user's problem first.

Today I'm focused on AI Engineering: designing and deploying LLM-powered systems and intelligent products in production — not demos.


🔭 What I'm working on

  • Training in AI Engineering at LIDR.co — LLMs, RAG, multi-agent systems, LLMOps
  • Certified Data Scientist (Associate + Professional) — DataCamp
  • Exploring AI-first product ideas in the Business Travel space

🧠 What I bring to the table

  • Product vision: 9 years owning strategy, roadmap, and user research as CTO
  • Data-driven mindset: built KPI systems, integrated NLP & OpenAI API in production
  • Builder mentality: I start from scratch — architecture to UI to analytics

🛠️ Tech I work with

AI/ML: Python · OpenAI API · LLMs · NLP · scikit-learn · TensorFlow · pandas

Backend: C# · .NET Core · ASP.NET · REST APIs · SQL Server

Data: Segment · Amplitude · KPI design · product analytics

Cloud & DevOps: Azure · Docker · Git · CI/CD
