What I'm looking for

I’m looking to build and optimize cloud data pipelines and ETL in Azure/Databricks, using SQL and performance tuning to deliver accurate, fast insights—and to collaborate with product and engineering teams.

I’m a Data Engineer focused on architecting and optimizing end-to-end data pipelines in Azure and Databricks. I’ve streamlined engineering workflows and improved data delivery speed by 40% through cloud-based automation and performance tuning.

In my integrations for Sanofi and COPA Energia, I automated data orchestration to ensure 99.9% data accuracy for critical BI and executive decision-making. I’ve engineered and scaled ETL processes with Informatica IICS, Snowflake, and AWS (S3), reducing manual intervention and improving processing efficiency by 30%.

I also bring full-stack product experience: I designed scalable web and mobile applications with Laravel (PHP), Vue.js, and Flutter, supporting 5k+ active users with 99% uptime. I enjoy mentoring teams—like training 10+ engineers in Colombia on Informatica IICS and Snowflake—and turning requirements into reliable, high-performing systems.
