Client work · case studies

Systems I've built for other companies.

The apps under Apps are mine. This is the other half of the work: Android apps for other companies' products — a guitar-tuner maker, a car marketplace, an EV-charging rewards programme, an AI parenting startup — and a full backend-plus-web planning system for a fibre contractor. Each case study says what the product does, what I built, and how.

Dynet dashboard: the City → Area → District → Building → Apartment hierarchy with counts, the five-step installation process flow, and completed, pending and scheduled installation totals

Dynet

Fibre rollout · Web · API

Districts arrive as the network operator's Excel sheet; Dynet turns them into buildings, flats and a work queue for six specialist roles — surveyors, planners, installers — with calendars, floor plans down to the cable, and live progress per district. API, web app and import pipeline, built by me.

Case study

Roadie Tuner home screen with the user's instrument profiles and tutorial cards

Roadie Tuner

Music hardware · Android

A free chromatic tuner for twelve instruments and the control centre for Band Industries' Roadie devices: connect over Bluetooth, push firmware, manage instrument profiles and 150+ alternate tunings. I built the Android app; 100K+ installs, rated 4.6 on Google Play.

Case study

Seez store screenshot: Find your next car — buy, lease, new, used — with search results for Toyota models in Dubai

Seez

Automotive marketplace · Android

Seez aggregated used and new car listings across the UAE, Saudi Arabia and Kuwait into one search, priced them with market data, and could identify a car from a photo. I built the Android app — 500K+ downloads — for a company that grew to a million users and was acquired by Pinewood Technologies in 2025.

Case study

PowerGoodies home screen: points balance, a Ready to charge card and an Add new card bonus

PowerGoodies EV Rewards

EV charging · Android

Public chargers are blocked by cars that finished hours ago. PowerGoodies rewards EV drivers with points for charging at partner operators in the Netherlands, Belgium and the UK and for unplugging right after the car is full — points they spend on gift vouchers. I built the Android app end to end: charge map, session tracking, timers, notifications and the rewards shop.

Case study

Bubu AI

Parenting · early childhood · Android

Bubu is an AI parenting companion: an assistant that answers from your child's own profile, sleep predictions, personalised stories and lullabies, and a nursery hub that connects parents with their daycare. I built the Android app — Kotlin, Jetpack Compose, 20+ Gradle modules — to parity with the iOS app, plus the Android teacher app for nurseries.

Case study

Not everything is on this page.

Banking and enterprise engagements sit under NDAs, so what's public here is the work that shipped to a store or a client's users. Ask, and I'll walk you through the rest in a call — architecture, scope, what went wrong, what shipped.
