When the substrate isn't the problem and a rebuild is overkill. We take what you've got and ship it to production — fixed scope, fixed price, the same senior engineer through to handover.
A Fix Sprint is fixed-scope, fixed-price production engineering — typically $3,000–$8,000 over two to four weeks. When your app's substrate is sound but specific things are broken — auth that doesn't hold, payments that don't reconcile, a flow that fails under load — a senior engineer fixes them in place and ships to production, rather than rewriting from scratch. Scope comes straight from the $499 audit.
The app is real. Users are in it. But auth doesn't quite hold, payments don't reconcile, a core flow breaks under load, or the AI agent keeps re-introducing last week's bug. None of it justifies starting over — and starting over would cost you months you don't have.
You don't need a rewrite. You need someone senior to go in, fix the specific things that are blocking you, and ship it — without turning a two-week job into a two-quarter rebuild.
Scope comes straight from the audit — the ranked risks, priced and time-boxed. No moving target.
The audit names the work; we quote it flat. You know the number and the date before we start.
We work in your existing stack and ship to production — no parallel rewrite, no flag day.
The corners that decide whether an app survives real users, closed properly.
The person who audited it fixes it and hands it back — no context lost between quote and code.
We stay on for a month after ship to catch anything the first wave of real traffic surfaces.
Every engagement starts with the $499 audit — the audit decides which of these four your app needs. We ship all four, so the verdict isn't biased toward the biggest invoice.
| Verdict | When it's the call | What we do | Cost | Timeline |
|---|---|---|---|---|
| Keep | The substrate is sound and the app holds. | You get the report and ranked risks, then we part ways. | $0 further | — |
| Fix | Blocking issues, but the platform itself is fine. | Fix Sprint — fixed in place and shipped to production. | $3K–$8K | 2–4 weeks |
| Rebuild | The platform itself is the ceiling. | Production Rebuild — Next.js + Postgres, migrated with no downtime. | $10K–$35K | 6–10 weeks |
| Retire | The honest call is to stop. | We put it in writing before you spend another dollar. | $0 further | — |
The $499 audit names what's actually broken and what's fine — so the sprint fixes the right things.
We turn the ranked risks into a fixed-price, fixed-date sprint. You approve the number before any code.
Senior engineering in your codebase, shipping to production incrementally — not a big-bang cutover.
Documented changes, a walkthrough, and 30 days of stabilisation support.
Every audit, fix, and rebuild runs through one senior engineer. Over 7+ years, Muzammil has shipped production software across Bubble, React Native, and Next.js — greenfield MVPs, three-sided marketplaces, and rescues of AI-generated codebases that couldn't deploy. The person who reads your app is the person who fixes it.
From the audit. The ranked risk list becomes the sprint backlog — we quote it flat and you approve before we start. No open-ended hourly billing.
We flag them, we don't silently absorb or expand. If something new is genuinely blocking, we re-scope transparently; if it's not, it goes in the report for later.
Yes — that's the point. A Fix Sprint is in-place production work, not a rewrite. If the substrate itself is the wall, the audit will say so and point you to a Rebuild instead.
Yes, scoped against the audit. Fixed price, fixed date, same engineer through handover.
Start with the $499 audit. If a Fix Sprint is the right call, we scope it flat and ship it — usually in two to four weeks.
