I fix slow SQL queries and broken databases
Bangladesh
Sobre mim
SQL specialist from Dhaka, Bangladesh. 3+ years fixing slow
queries, writing stored procedures, and troubleshooting databases for
enterprise systems — including BRAC(largest NGO of the world)'s ERP.
I dig into root causes: bad indexes, messy joins, wrong data. Also
comfortable with Oracle, PostgreSQL, and ASP.NET Core/Entity Framework
if your issue touches the app layer too.
I explain what I find in plain language and always protect your data
before making changes. New to Fiverr, so extra motivated to deliver
great work and earn honest reviews.
Let's fix what's slowing you down.
