Data Engineer focused on Snowflake reliability, automation, and faster pipelines.
BoliviaWhat I'm looking for
I’m a Data Reliability Engineer at Nice, focused on securely operating and improving our Snowflake platform—managing user accounts, roles, warehouse/database access, and MFA, while automating day-to-day work. I’ve built Python AWS Lambda functions to bulk-insert users into Snowflake DataShare accounts and recommend optimal Cluster Keys, created cost/performance monitoring dashboards in StreamLit and Snowflake, and integrated metrics into Grafana; I also reduced a key pipeline from over 60 minutes to just 4–8 minutes and led a complete multi-region NRT historical data migration within defined maintenance windows.
Before that, I worked as a Data Engineer at SITEC, where I designed and implemented end-to-end data pipelines, maintained MSSQL scripts for analytics reports, and orchestrated ETL/ELT processes using Apache Airflow to optimize data quality and operational efficiency. Earlier, I developed full-stack features with Angular, Django (REST APIs), Node/Express, and Ionic, including OpenCV-based image detection—experience that helps me deliver data infrastructure that’s faster, more scalable, and easier to operate.
