What I'm looking for

I seek remote-first roles focused on on-chain analytics, modern data pipelines, and distributed systems where I can build scalable data infrastructure and improve data quality and performance.

I am a data engineer with over 10 years building scalable data platforms across banking, telecom, and tech, with strong expertise in SQL, Python, warehouse modeling and performance optimization. I recently expanded into blockchain data infrastructure, designing Ethereum indexers (ERC-20 transfers and Uniswap V3 swaps) using Web3.py and PostgreSQL, including ABI-based log decoding, adaptive RPC windowing, and bulk ingestion.

My career highlights include developing and optimizing ETL processes for SQL Server and Greenplum data warehouses, refactoring legacy pipelines for maintainability and performance, integrating new data sources at enterprise banks, and automating analytics workflows for product and marketing teams. I thrive in remote-first environments focused on on-chain analytics, modern data pipelines, and distributed systems.
