Backend & SQL Fix Sprint: 1 Bug, 1 Endpoint or 3 Slow QueriesCENG ZENG
A small, fixed-scope backend sprint for when something in your app is broken, missing or slow and you need it handled quickly.
Pick one of these:
Fix one bug in a Java/Spring Boot backend or a MySQL/PostgreSQL database
Build or fix one REST API endpoint
Optimize up to 3 slow SQL queries (indexes, query rewrites, EXPLAIN analysis)
Who it's for: startups, small SaaS teams and e-commerce stores with a Java or SQL backend that need a reliable developer for a scoped task.
My background: Java/Spring Boot, MySQL and Vue. I've migrated a production system from Oracle to MySQL and built back-office tools and KPI dashboards for a lending business.
Live demos: tidelightstudio.com/demos
How it works:
You describe the issue and share repo or database access (or a reproducible example).
Scope is confirmed before payment: I review the issue first, then we agree in writing on the exact fix and what counts as done.
I deliver the change with a short written explanation.
You get 1 round of revisions.
The three options are different sizes, so I check yours fits one sprint before you pay. If the issue is larger than one sprint (for example, a query that needs a schema redesign), I quote it first and do no extra work without your approval.
