What I'm looking for

I seek a remote-friendly role where I can own SQL-driven analytics, build reliable ETL pipelines, mentor colleagues, and grow into Web3/on-chain analytics.

I am a SQL-focused Data Engineer and Analytics Engineer with over seven years of experience building ETL pipelines, data models, and dashboards for enterprise clients. I transform raw data into clean, reliable datasets and well-defined KPIs that support operational and strategic decisions.

I have designed and maintained analytical datasets supporting thousands of KPIs and hundreds of users, built 20+ ETL pipelines, and migrated legacy BI solutions to modern analytics platforms using PostgreSQL, Apache Airflow, Python, and BI tools. I work hands-on, pay close attention to data quality, and collaborate with stakeholders to translate business questions into actionable SQL-based analyses.

I thrive in remote environments and am exploring Web3 and on-chain analytics, creating SQL dashboards in Dune and learning on-chain data tooling to expand my analytics expertise.
