Slow queries killing your app? Stored procedure throwing errors? Need something built from scratch?


I work as a Data Integration Engineer at a major insurance company SQL Server is my daily stack. I build and maintain production DWH pipelines and stored procedures.


WHAT I DO:

- Write SQL queries from scratch (SELECT, JOINs, aggregations, window functions, CTEs)

- Fix broken or slow queries

- Write and refactor stored procedures

- Query optimization and indexing recommendations

- T-SQL for SQL Server environments


WHAT YOU GET:

- Clean, commented, production-ready code

- Short explanation of what changed and why

- Same-day delivery on simple fixes


BEFORE YOU ORDER:

Message me first with your query or problem description. I'll confirm scope and which package fits.


Note: I only work with SQL Server (T-SQL). If you're on MySQL or PostgreSQL, message me first.
