I will optimize your slow sql queries and improve database performance
I fix slow SQL queries and broken databases
About this Gig
Is your Database slower than it should be? A single badly
written query, a missing index, or an inefficient join can silently
cost you hours every week and most of the time, the fix is smaller
than people expect.
I'm a backend and database engineer with 3+ years of hands-on SQL
experience supporting production systems, including BRAC's enterprise
ERP and a core banking platform. Performance troubleshooting is
something I do regularly, not something I learned for this gig.
WHAT I'LL DO:
Analyze your slow query and find the actual root cause
Rewrite and optimize it for better performance
Check indexing and suggest improvements where relevant
Explain clearly what was wrong and what I changed no jargon dump
Provide a before/after performance comparison
WHAT I NEED FROM YOU:
- The SQL query (or queries) that are running slow
- Table schema / structure (or database access, if you're comfortable)
- Any context on how the query is used (report, app feature, etc.)
I treat every database with care I'll always explain risk before
making any change, and I recommend working on a backup or test copy
whenever possible.

FAQ
Do you need access to my live database?
Not always — often I can optimize a query with just the query text and table structure. If deeper access is needed, we'll discuss a safe approach first.
What if I have more than 7 queries to fix?
No problem — message me for a custom offer based on your specific workload.
Do you work with databases other than SQL Server?
I have experience with Oracle and PostgreSQL.
