About me

Pascal Garcia Esteves

Senior AI & Data Engineer with 8+ years of experience building data and AI systems that work in production.

I started in 2016 at Galp, where I spent 6 years building machine learning models and data pipelines in a real enterprise context. Then at Defined AI, I led a team delivering fast solutions with LLMs, cloud and data. Today, through Synchronized Silence, I work as a freelancer for clients like EDP — as a Data & AI Tech Lead.

I genuinely like building things. Not presenting slides or advising from a distance — taking a real problem and delivering code that works, with good practices and in a sustainable way.
