About this Gig
Are you drowning in SQL query hell? Do you need someone to help you write or optimize your SQL queries so you can focus on other priorities? Let me help.
I'm a data analyst with over 5 years of professional experience working with SQL Server and PostgreSQL in healthcare and business environments. I've built reporting systems, automated data processes, and optimized slow queries that were dragging down performance times.
If you order from me, I can write new queries from scratch based on your requirements - whether that's pulling specific data, calculating metrics, or combining information from multiple tables. I can also fix or optimize existing queries that are running slow or not returning the right results. And if needed, I'll explain how your queries work so you or your team can maintain them going forward.
How do I do this? I'll ask questions upfront to make sure I understand what you need and why. I write clean, well-structured SQL that's easy to read and modify later. If something's not working right, I'll troubleshoot until it does.
I work primarily with SQL Server and PostgreSQL, but I'm comfortable with MySQL as well.

FAQ
What information do I need to provide?
I need your database structure (table/column names, relationships) and what you're trying to accomplish. Tell me the business problem you're solving - this helps me write a query that actually meets your needs. Screenshots or sample data are helpful too.
Which package should I choose?
Basic is for simple SELECT queries. Standard is for multiple tables, subqueries, or aggregations. Premium is for optimization or complex logic. Not sure? Message me with your needs and I'll recommend the right package.
Do you work with [specific database]?
I specialize in SQL Server and PostgreSQL, and I'm comfortable with MySQL. If you're using a different platform, message me first and I can let you know if I can help.
Do you need to access my database directly?
No, I don't need direct access. You provide the structure and requirements, I write the query, and you run it in your own environment. This keeps your data secure.
What if the query doesn't work?
That's what revisions are for. If there's an issue with the query I delivered, I'll troubleshoot and fix it within your package's revision limit.
