What I'm looking for

I’m seeking a data-focused role where I can architect scalable analytics systems, own end-to-end pipelines, mentor teams, and deliver production-ready ML and reliable BI in a collaborative, outcome-driven environment.

I’m a Data Engineer specializing in building reliable, high-performance analytics systems for pricing, revenue, and operations, with hands-on experience across data modeling, ingestion, pipeline automation, and BI reliability.

At Avantstay I owned the end-to-end data layer, architected a ClickHouse + PostgreSQL analytics ecosystem, and optimized multi-terabyte ETLs from 7+ hours to under 30 minutes while enabling sub-second reporting and governance.

I also deliver production-ready ML/NLP work, implement CI/CD for data pipelines, mentor engineers, and drive operational improvements such as a Slack-based NPS loop that increased NPS by 15% in 30 days.
