We fix apps, then keep them fixed

The companion app dragging down your hardware. The consumer app nobody has touched in a year. We find what's actually failing, ship the fixes, and stay on it after.

The audit is free. We put your app through real use and pinpoint what's failing. No commitment.

Already shipped, and nobody looking after it? We do that ongoing.

What we do
Rescue

App rescue

Broken, buggy, or abandoned apps rebuilt into ones people rely on. Crash and freeze fixes, hardware and Bluetooth connectivity, performance, the reliability bugs quietly bleeding your reviews.

Audit

Reliability audit

We find what's actually breaking your app and rank it by impact, no repo needed. Want it at the code level? Share repo access and we go file by file. Usually the first thing we do, and it's free.

We also build from scratch

Mobile
iOS and Android via React Native: one codebase, native performance.
Web
Full-stack Next.js and TypeScript. Fast, typed, deployed on Vercel.
AI integration
Claude, GPT, Gemini. Streaming, cost control, caching.
Ongoing

The problem usually isn't one bug.

Most of the apps we get sent have been broken for a while, because nobody has been looking at them. Whoever built it moved on, and the small things piled up until they were one big thing.

Fixing that once helps, though it only lasts if somebody keeps looking afterwards. For companies with software and no one whose job it is, that's the work we do every month.

You don't manage us
We say what we're picking up before we start. It goes ahead unless you object.
It starts with the audit
We won't quote ongoing work on a codebase we haven't read. That part is free.
Nothing lives in our heads
What changed and why gets written down in your repo as we go, not on the way out.

How we work

From broken build to shipped fixes

A clear four-step process. You always know where your app stands and what happens next. No black box, no surprises.

01

Audit

We put your app through real use and cite exactly what's breaking, ranked by impact. It's free.

02

Plan

The findings become one fixed-fee number and a clear order of attack, reliability bugs first.

03

Fix

We work in your repo and your infrastructure, shipping the crash, freeze, connectivity, and performance fixes.

04

Ship

We deploy to your stores and hosting, then verify the failures are gone in the live app, not just on our machine.

Client work

Lettuce Grow

Reliability engineering · Mobile · 2026

Lettuce Grow makes a hydroponic growing system that people set up and run from their phone, and we came in on the companion app to work on Bluetooth pairing and lifecycle remediation across iOS and Android, delivered over two phases.

ArtCopy

Lead developer · Mobile + Web · 2026

ArtCopy is a realtime multiplayer drawing game on iOS, Android and web, and we rebuilt the drawing engine and the multiplayer queue so it stopped lagging, crashing and desyncing partway through a game.

AceStudy

Reliability engineer · Web · 2025–2026

AceStudy is an AI study app we joined after the first build, and we fixed the signup flow that was dropping people's work, the concept map that froze under real use, and the billing across its subscription tiers.
