I will write custom sql queries and clean up your database
About this Gig
I write custom SQL queries, optimize existing databases, and clean up messy datasets (Excel, CSV, SQLite, MySQL).
For my Computer Engineering thesis, I built a system that automatically translates natural language into SQL queries so I have a strong grasp of both writing complex queries and making data accessible even to non-technical users.
What I offer:
Optimized, tested SQL queries
Database cleanup and reorganization
Clear explanation of what each query does
Support for follow-up questions after delivery
Send me a description of your database or data problem, and let's find the best solution together.

FAQ
What information do you need to get started?
Just send me your database structure (or a sample of your data) and a description of what you need — I'll take it from there.
Can you work with my existing database, or do I need to send you sample data?
Both work! I can optimize/write queries for your existing database, or if you prefer, you can share a sample dataset and I'll build from that.
What if I need more revisions than included in my package?
No problem — additional revisions are available as a paid extra, or you can upgrade to a higher package for more included revisions.
