What I'm looking for

I’m looking for a remote role where I can build and optimize cloud data platforms—ETL/ELT pipelines, distributed query engines, and CI/CD-driven benchmarking—partnering with data science and engineering teams to deliver reliable performance and data quality.

I’m a Senior Data Engineer with 7 years across cloud data platforms, ETL/ELT pipelines, and distributed query engines like Trino. I’m deeply strong in Python and SQL, and I enjoy turning complex performance and data-quality needs into reliable systems.

Most recently, I built automated multi-vendor benchmarking infrastructure for large-scale analytics query engines across AWS and Azure. I engineered self-service, click-to-run Docker benchmark generation (including TPC-DS up to SF10000) and delivered fully code-driven onboarding using Pulumi and EKS, with end-to-end CI/CD via GitHub Actions.

From fintech lending and payments to feature ownership, I’ve shipped production pipelines on AWS serverless architectures (Lambda, Step Functions, Athena, RDS), promoted data models from pandas prototypes to orchestrated production SQL, and mentored junior engineers. I work comfortably in async, remote collaboration on globally distributed teams.
