What I'm looking for

I’m looking for a data role where I can build SQL/Python pipelines, deliver BI dashboards, and grow into on-chain analytics—turning raw data into clear stories for non-technical stakeholders, with fast feedback and iteration.

I’m a Data Analyst with hands-on SQL and Python experience in a production Databricks/SparkSQL environment, and I’ve delivered machine learning models and Power BI dashboards during a data science internship. I move confidently from raw, messy data to a story non-technical stakeholders can act on.

Currently, I’m upskilling in blockchain analytics, exploring on-chain data via Dune Analytics and building familiarity with DeFi protocol metrics like TVL, wallet activity, and transaction flows. In my recent role, I write and optimize SQL for large-scale analysis, troubleshoot data quality issues across pipelines, and document table lineage with reusable query templates.
