Your app's audit
closed out, not filed away.
Part-time Flutter/Node developer for a live app that already has a technical audit and a growing backlog. Bugs get fixed, tested, and shipped as a PR with a written fix log — not a proposal to read later.
// practiceService.js — before/after - state.streakCount += 1; // every call, every day + if (gap === 1) state.streakCount++; // FIX #2 — same-day sessions no longer // double the streak. Proven by a test, // not just this diff: $ npm test ✔ FIX #2 — same-day session (11ms) ✔ 18 tests, 18 passed
The audit is done. The fixing isn't.
A completed technical audit is progress — until it's a document nobody has time to act on.
The audit findings are sitting in a doc
Someone paid for a review. Nobody's paid for the follow-through yet.
Store reviews mention crashes you can't reproduce
Real users hit them on real devices, in the gaps a quick manual test never covers.
Only one person ever understood the backend
And they've moved on, or moved to the roadmap, or both.
New features keep losing to firefighting
Every sprint starts with "let's build" and ends with "let's patch."
You need a part-time developer, not a full hire
The workload is real but it isn't a full-time role — yet.
You want proof before you commit
Fair. That's what the sample report below is for.
Four steps from audit to shipped fix.
Send the audit + repo access
Or a quick description of what's wrong — a fresh triage happens either way.
Scoped & priced
Bug-Fix Sprint, full Audit-to-Fix Package, or straight into a monthly retainer — whichever fits the backlog.
Fixed, tested, PR'd
Each fix lands as a reviewable PR against your real repo, with tests where your codebase has a test setup.
Written fix log delivered
What was broken, why, the fix, how it was verified — mapped to your audit line by line.
A full sample fix report — real code, real tests.
Built independently on a composite "Practice" feature (session logging, streaks, a weekly goal) — the same shape of feature named in this brief — so you can see the standard of work before committing to it.
One flat sprint, or a retainer that compounds.
No hourly guesswork. Pick the entry point that matches how much backlog you're carrying.
Bug-Fix Sprint
- Up to 5 audit-flagged (or freshly triaged) P0/P1 bugs
- Fixed across Flutter and/or Node
- Delivered as a patched branch/PR
- Written fix log — what, why, how it was verified
- 3-5 business day turnaround
Audit-to-Fix Package
- Every audit finding worked, P0 down to polish
- Flutter client and Node backend, whole backlog in one pass
- Fix log mapped line-by-line to your audit
- Patched repo / PR set, ready to review and merge
Monthly Maintenance Retainer
- New bug reports as they come in
- OS, dependency & store-compliance updates
- Incremental feature work (e.g. the Practice feature)
- Monthly written report of what shipped
- $897/mo for ~16 hrs — ask for details
Tell me what's broken.
A link to your audit or repo (read access only, or just a description) is enough to scope a sprint.
