[Talk to a senior engineer](https://zeroic.in/book?service=code-rescue) [See the work](https://zeroic.in/work) **Starting at** $6,000 **Timeline** 2-4 weeks **Products shipped** 40+ ## Where most Cursor-built apps are Cursor keeps a developer in the loop, so its apps usually rest on sound foundations. What slips through is slower to show: queries that fire once per row, migrations nobody reviewed, a new pattern every sprint and no tests to catch it. We fix those seams so your team can keep shipping. Pages fire one query per row → Queries joined, indexes in place Migrations run without a review → Every migration reviewed before it runs Each feature follows a new pattern → One architecture, written down No tests, so every change is a gamble → Tests on the paths that matter ## What we fix in Cursor-built apps ### N+1 queries Without the schema in view, generated code often loads a list and then fires one query per row. Twenty rows become twenty-one calls. We join at the query level and add indexes. ### Migrations you can trust A migration that runs in the wrong order can need a backup restore to undo. We review every migration before it reaches production and make them safe to run more than once. ### Architecture that stopped drifting Each prompt solves the problem in front of it, so a codebase ends up with three ways of doing the same thing. We pick one, refactor towards it and write the decision down. ### Rules for the next prompt We set up project rules in .cursor/rules with your schema and conventions, so the code your team generates after we hand over follows the same patterns we put in place. ## How it works 1. 01 ### Review (3 days) We read the code, the database and the deploy setup, and tell you plainly what to keep, what to fix first and what the fix costs. 2. 02 ### Fix the seams Senior engineers fix the queries, migrations and patterns causing the pain, in your repository alongside your developers. 3. 03 ### Harden and hand off Tests, monitoring and docs go in before handover. You own the code and every account, with 6 weeks of support under real load. Starting at $6,000 Fixed scope and fixed price, agreed after the 3-day review. Not sure what is wrong yet?

Code Rescue starts at $6,000 for a fixed scope, agreed after a 3-day review. Cursor rescues are usually the most targeted: a handful of specific fixes rather than a rebuild. Not sure yet? A Security Audit, from $1,000, shows what needs fixing first. Do you need to rewrite our code? Rarely. Cursor codebases are usually sound underneath. We fix the specific seams causing pain and leave your team with code they can keep building on. Can you review code before it goes to production? Yes. On a retainer, a senior engineer reviews pull requests and migrations as your team ships, so problems are caught before your users see them. Will you work alongside our developers? Yes. We work in your repository and your tools, pair with your team on the fixes and leave the rules and tests in place for them. Do we own the code afterwards? Yes, 100%. You own the code, database, docs and credentials. No lock-in and no proprietary platform. ## Hear from us within 24 hours. **Prashant and Khushi** Partners @ Zeroic Cursor codebase getting harder to change?
