DDRTAndroid & iOS apps
Native-quality apps from one codebase — React Native and TypeScript — with offline-first storage, notifications, and real attention to design. Built for the phones people actually carry, on networks that come and go.
Services
We design and build software. End to end.
DDR Technologies is a Ghanaian software company. Hospitals are our deepest work — but the craft is general: enterprise web platforms, Android and iOS apps, desktop and on-premises systems, and the AI and integrations that tie them together. Designed, engineered, shipped, and supported by the people whose initials are on the company.
What we build
Six things we do well.
One team covers the whole stack — so your app, its backend, its admin screens, and its deployment are one coherent piece of work, not four vendors.
Mobile
Web
Enterprise web platforms
The kind of systems institutions run on: role-based security, audit trails, configurable forms and workflows, live dashboards. Our own platform runs a whole hospital — yours doesn't have to be that big.
Desktop & on-prem
Desktop and on-premises software
Cross-platform desktop applications, and server software packaged to run on your own hardware — including entirely offline, where the internet is a feature rather than a requirement.
AI & data
AI and analytics
Assistants that can run locally so your data never leaves the building — plus the unglamorous parts done right: reporting, exports, and data migration from whatever you use today.
Integrations
Payments and messaging
Mobile money and card payments, WhatsApp, SMS, and email — plus the specialist integrations we've done in healthcare, from laboratory analysers to national claim formats.
Design
Product design
Design systems, motion, and accessibility taken seriously — software people don't need training to want to use. If a screen needs a manual, we consider it unfinished.
Selected work · Mobile
Drafting Room — a study app we built and ship.
Our own exam-prep app for The Open Group's TOGAF® certification: a spaced-repetition study system with timed mock exams, scenario practice, drills, and a readiness gauge — designed with the warmth of paper rather than another dark dashboard.
Built with React Native, Expo, and TypeScript on an offline-first SQLite store, with daily reminders and full backup export. One codebase: it ships to Android today, and the same source builds for iPhone.

Selected work · Platform
Built in-house, demonstrable live.
We show our own products because they are the honest evidence: they exist, they are finished work, and we can walk you through every one of them on a call. When we take on your project, the team that built these builds yours.
Enterprise web
DDRT — one platform for a whole hospital
Thirteen integrated products — clinical care to accounting — on one secure core: one sign-in, one patient record, one ledger, one audit trail. The deepest thing we've built, and the proof of how we build. The architecture has its own page →
Mobile web app
Patient portal — installs on any phone
A patient-facing app that installs from the browser on Android and iPhone — appointments, results, bills, refills — and keeps working when the network doesn't. No app store required, updates arrive instantly.
Retail
Point of sale — tills, shifts, mobile money
A multi-channel retail POS on the same platform core: barcode-fast checkout, cashier shifts and reconciliation, promotions, and mobile-money tenders alongside cash and card.
Analytics
Dashboards and reporting
Live operational dashboards, scheduled reports, and regulator-ready exports — the layer that turns a running system into answers for the people accountable for it.
Also on the bench
- Distribution & field sales — a packaged-water distribution product with production, route sales, and an offline field app.
- Desktop consoles — cross-platform desktop applications for administration and operations.
- On-premises appliance — the whole platform packaged to run on a server in your building, fully offline.
The stack we reach for
TypeScriptReactReact NativeExpoNode.jsPostgreSQLSQLiteElectron
Modern, boring-on-purpose technology — the same stacks the world's best product companies use, chosen so your system is maintainable for a decade, not fashionable for a year.
How an engagement runs
Four steps. No mystery.
Step 1
Discover.
We start with the workflow, not the feature list — what the software must make true on the ground, for whom, on which devices. You leave the first conversation with a written scope and an honest estimate.
Step 2
Design first.
Screens you can react to before a line of product code is written. Cheap to change on paper, expensive to change in production — so we argue about design early, on purpose.
Step 3
Build in the open.
Working software early and often — you watch the product grow and steer it while steering is cheap. No six-month silence that ends in a surprise.
Step 4
Ship and stay.
We deploy, we train, and we support what we build. The people who wrote the code answer the phone — there is no tier-one script between you and an engineer.
