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.
