About

Hi I am Gabriel (Gabu) Bellon 👋

I’m a geek interested in understanding how things:

🎮 be it completing a game; 📚 reading all the books I can; 🎥 seeing a very good trilogy; 🍺 or even understanding the difference in flavors between the beers I can!; 🗺️ I like to know about philosophy and politics and understand how it impacts our world and our society!; 💬 I believe that healthy discussions are good for our life constructions. 👨‍💻 I’m a Lead Data Engineer at phData, based in Brazil, with over 15 years of experience across Data Engineering, Analytics, and Data Science. I architect and maintain ETL pipelines and modern data stacks for clients in healthcare, fintech, investment banking, and telecommunications, working daily with Snowflake, dbt, Airflow, Python, and AWS — and increasingly leaning on LLMs (Claude included 🤖) to speed up development and documentation.

🚀 Directed the transition of legacy systems to a modern data stack on Snowflake + dbt, cutting consolidation times from hours to seconds; 🏦 Delivered high-frequency data pipelines for investment banking clients ingesting financial indices; 🩺 Built data integrations at Trusted Health that let hospitals plan nurse staffing months in advance instead of weeks; 📉 Shipped a churn-prediction ML model at Conta Azul serving 60k+ simultaneous predictions in under 2ms at 89%+ accuracy, co-authored with AWS; 🎓 Certified in SnowPro Advanced: Data Engineer, dbt Fundamentals, Fivetran Technical Accreditation, and Apache Airflow 2 Fundamentals; I still tinker with side projects on GitHub and occasionally post on Bluesky — mostly a mix of data engineering, Brazil life, and whatever I’m nerding out about that week.
