What I'm looking for

I work with freelancers, small SaaS companies, and agencies without an in-house DBA, helping diagnose slow SQL Server queries and providing ongoing performance support.

At Corsal S.A., I administer and optimize SQL Server databases in production, tuning complex queries for registration and membership systems.

I analyze execution plans and indexes, and rewrite queries with multiple joins to reduce response times.

Alongside database work, I develop AI-integrated solutions with Python and FastAPI backends, Flutter and Next.js frontends, and Gemini models.

I work with freelancers, small SaaS companies, and agencies without an in-house DBA, from diagnosing slow queries to ongoing performance support.
