Your customers and team need
your system in their pocket.
I build mobile apps for iOS and Android that extend your existing web system to mobile. Built with React Native so both platforms get the same app from one codebase. Companion apps that work with your backend, not beside it.

When your users need mobile access
You have a web application, a dashboard, a booking system, or an internal tool that works well on desktop. But your customers or team need access from their phone or tablet. They need to check status, submit data, receive notifications, or use a key feature while they are away from their desk.
Purpose-built. Not patched together.
You do not need a separate app company. You need the same developer who understands your web system to extend it to mobile.
What I build
Companion Apps
Mobile versions of your existing web application or specific high-use features. Connected to your existing backend and database — not a separate system.
Field & Reporting Apps
Apps for teams in the field — data collection, reporting, inspections, delivery tracking. Built to work with your existing web infrastructure.
Customer-Facing Mobile Apps
Self-service apps for your customers — booking, ordering, account management, notifications. Extending your web platform to mobile.
Production-Grade Stack
These are not theoretical skills — I have shipped production applications with all of them.
Technologies I Use
Both platforms at once
With React Native, I can develop for both Android and iOS simultaneously. One codebase, two platforms — saving you time and money while delivering a native experience on both.
Mobile apps work best as companion apps to an existing web system. If you do not have a backend or web application yet, we may need to build that first. I handle both — see my Cloud Applications and API services.

How It Works
Tell me what needs to go mobile
Describe the web system, the feature set, and the users who need mobile access. What should the app do?
I review and scope
Within 24 hours, feedback on the best approach — what should be in the app, how it connects to your backend, and the timeline.
We build and ship
Development in phases with regular builds you can test. The app is submitted to the App Store and Google Play when ready.
Typical Engagements
Mobile companion apps are typically scoped alongside or after the primary web system build.
- Simple companion apps: 4-8 weeks
- Feature-rich mobile apps: 2-4 months
- Full mobile + web builds: scoped as a combined project
One developer. The entire project.
No account managers, no hand-offs. You work directly with me from first conversation to final delivery. I scope every project individually and give you a clear estimate before any work begins.
Frequently Asked Questions
Do you build for both iOS and Android?
Yes. I use React Native which compiles to native code for both platforms from a single codebase. You get both apps from one development effort.
Does my mobile app need a backend?
Usually yes. Most mobile apps connect to a server for data, authentication, and business logic. If you already have a web system or API, the app can connect to it. If not, I can build the backend too.
Can you build a standalone mobile app?
Yes, but companion apps that extend an existing system are where I add the most value. If you need a standalone app, I can evaluate fit during the scoping phase.
How much does a mobile app cost?
It depends on complexity, features, and whether a backend already exists. I scope every project individually and give you a clear estimate before work begins.
Do you handle App Store and Play Store submission?
Yes. I compile the app, handle the submission process, and work through any review issues from Apple or Google.
Need your system on mobile?
Tell me what you need. I review every enquiry personally and reply within 24 hours with feedback on feasibility, approach, and timeline.
