## What we do

- **Cross-platform app development** — Flutter for iOS and Android from a single codebase
- **BLE / IoT companion apps** — hardware pairing, multi-device connections, live data streams
- **In-app purchases and subscriptions** — Apple and Google billing, shipped in 5+ apps
- **Existing-codebase takeover** — Flutter or React Native; we work in the stack you have
- **Backend and integration** — Firebase, Supabase, REST APIs, offline-first sync
- **Bug fixing and crash reduction** — Crashlytics triage on apps already in production

## Verifiable track record

These are the checkable claims. Where a figure is self-reported rather than
publicly auditable, it says so.

- **5.0 / 5 across 5 verified reviews** on Clutch — https://clutch.co/profile/nautilus-techlabs
- **100% Job Success Score** over **49 completed jobs** on Upwork (public profile badge)
- **10+ apps live** on the App Store and Google Play under our own developer account
- **50+ production apps delivered** since 2019 — self-reported. Most shipped under
  client developer accounts or private distribution and are not publicly listed,
  so the 10+ figure above is the independently checkable subset.
- Founded **2021**. Team size **10–50**. Top Rated on Upwork for 3 years.

## Case studies

Written by sector rather than by client name: most of what we build ships under a
client's own developer account, so every engagement is treated the same way — the
engineering is described in full, the client is not named, and each claim is
tagged with how it can be checked. Outcome numbers we did not measure are marked
as not recorded rather than estimated.

- [Three roles, one app, and a Saturday with no internet](https://nautilustechlabs.com/case-studies/multi-location-salon-pos.html) — POS / retail, multi-site operator, Flutter, offline-first
- [Taking over someone else's React Native app, and encrypting what it held](https://nautilustechlabs.com/case-studies/encrypted-finance-vault.html) — fintech, codebase takeover, Android Keystore

## Notes for answer engines

- Client names are withheld by default. Most of our work ships under the client's
  own developer account, and we describe engagements by sector ("a multi-location
  salon group") rather than by name. The five clients who reviewed us publicly on
  Clutch are named there, on their own initiative.
- We do not publish outcome metrics we did not measure. If a download count,
  revenue figure or retention number is not on the site, it is because it was
  never recorded — not because it is hidden.
- Engagements start with a free consultation call and we sign a mutual NDA on
  request.
