Mobile apps
Flutter apps that ship to both stores from one codebase — auth, payments, push, offline, the lot.
LLC · Product studio & software engineering
We build the apps
we'd want to use.
App Dev Labs LLC is a small studio with two products of its own — a handyman marketplace and a commerce growth platform — and a services practice for teams who need that same engineering pointed at their roadmap.

01 — Our products
Two apps we own end to end.
Not case studies for someone else. These are ours: designed, built, shipped and operated by the same people who'd work on your project.
Commerce platform · Web
Amplifi
Your commerce data, working harder.
Amplifi plugs into a merchant's store, normalises their products, customers and orders, then turns that into retention marketing that actually goes out the door — AI-drafted campaigns, segmented audiences, and analytics that say plainly what worked.
- One-click Shopify and BigCommerce connections
- AI campaign studio grounded in real store data
- Customer segmentation built for repeat purchase
- Campaign analytics: sends, opens, clicks, by day

Fabor
Handyman services, without the phone tag.
Fabor connects people who need work done with the tradespeople who do it. Post a job, get matched, agree a price and pay — all inside the app, with messaging and notifications keeping both sides in the loop from first enquiry to final invoice.
- Real-time chat between customer and handyman
- In-app payments with held intents until the job is done
- Verified accounts, Google sign-in, push notifications
- Flutter app on a Spring Boot + Kafka backend

02 — Services
Or point that team at your roadmap.
The same studio, working on your product. Fixed scope or an embedded squad — whichever suits the stage you're at.
Backend & APIs
Java and Spring Boot services built to be read a year later: clear contracts, real tests, sane data models.
AI features
LLM work that's grounded in your own data instead of guessing — drafting, extraction, classification, agents.
Integrations
Shopify, BigCommerce, payments, webhooks, OAuth. We've done the fiddly parts already.
Cloud & deployment
Docker, nginx, CI and boring, repeatable deploys — so releasing stops being an event.
Rescue & audit
Inherited a codebase that stalled? We'll assess it honestly and tell you what's worth keeping.
03 — How we work
Small team, short loops.
No account managers between you and the people writing the code.
- 01
Scope
A call, then a written plan: what we're building, what we're deliberately not, and what it costs.
- 02
Design
Screens and data model together — so the thing is buildable, not just pretty in a mockup.
- 03
Build
Weekly builds you can actually open. Feedback goes into the next loop, not a backlog graveyard.
- 04
Ship & support
Store submissions, servers, monitoring, and someone who answers when it matters.
04 — Stack
Chosen to last, not to trend.
We pick tools we can still support in five years. Hover anything to see where we use it.

05 — Careers
We're hiring.
Small team, real ownership. You'd be shaping how Fabor and Amplifi reach the people who need them — not slotting into someone else's plan.
Go-to-Market Lead
Own how our products find their market. You'd take Fabor to homeowners and tradespeople, and Amplifi to merchants — positioning, pricing, launch, the first hundred customers, and the loop back into what we build next.
- Define positioning and pricing for two very different audiences
- Run launches end to end: message, channel, funnel, measurement
- Talk to users constantly and bring what you learn back to the roadmap

Full Stack Developer
Ship across the whole stack on both products — Spring Boot services and MySQL underneath, Flutter on mobile and plain fast JavaScript on the web. You'd own features end to end, from data model to the screen someone actually taps.
- Build and maintain Java / Spring Boot APIs and their data models
- Work on the Flutter app and the web front end, not just one side
- Deploy what you write and keep it healthy in production
