Senior software engineer specializing in data engineering and Python backend development.
United StatesWhat I'm looking for
I am a senior software engineer focused on building scalable data platforms and Python backend services for analytics-driven SaaS products. I design and implement distributed data pipelines, RESTful APIs, and workflow orchestration to deliver reliable, high-throughput data processing.
Across multiple roles I have built ETL and stream-processing systems with Apache Spark, Airflow, and Pandas, optimized storage and data models in PostgreSQL and MongoDB, and containerized services for Kubernetes deployments. My work has improved pipeline throughput and data availability for analytics teams through automation, testing, and performance tuning.
I value pragmatic engineering, data reliability, and collaboration within agile teams, and I bring measurable impact—improving pipeline throughput, processing efficiency, and reporting readiness—while driving scalable solutions for analytics and reporting use cases.
