What I'm looking for

I seek roles building scalable data or platform systems where I can improve performance, reduce cost, and drive observability in collaborative, engineering-driven teams.

I am a polyglot software engineer focused on building distributed data platforms and real-time systems at scale, with hands-on experience across Spark, Airflow, Druid, and cloud infrastructure.

At Nielsen, Amazon, and Rigi I architected petabyte-scale ETL pipelines, event-driven microservices, and analytics platforms, delivering measurable outcomes including 42% runtime reductions, $7K monthly cost savings, and 99.95%+ uptime.

I blend backend, full-stack, and ML expertise to ship resilient systems—optimizing performance, cost, and observability while driving product impact and operational excellence.
