Your data infrastructure looks fine on paper, but it still can't answer a basic business question before the meeting's over. That's the gap I close, end to end. I'm a senior data engineer with 7+ years building pipelines that run in production without breaking at 6am. My core stack is Snowflake, Databricks, dbt and AWS, with Python and Airflow holding it together, but the tools matter less than the outcome: reliable data your whole team actually trusts. A few things that show how I work. I migrated a 200-view mart off Databricks and rebuilt it natively in Snowflake SQL. I built CI/CD for a US healthcare client using Schemachange and Snowflake, with automated data-quality checks and deployment gating so bad data never reaches production. Earlier in my career I cut processing time 25–40% by moving legacy scripts to Spark, saved a business team 30+ hours a month by automating their reporting, and redesigned Power BI dashboards that cut reporting time 40% and finally got finance and ops to actually use them. I work as an independent contractor, no middleman, no overhead, no ticket-closing. I take your problem on as mine, ask the business questions first, and design something your team can maintain without depending on me forever. If your data is slow, unreliable, or just not being used to make decisions, let's talk.
