What I do

End-to-end builds for web and mobile.

From the database to the last button, I take products from idea to launch — and choose the stack that fits your timeline and budget, not the other way round.

Speciality

Management systems

Inventory, HR, school, clinic, CRM, and custom operations platforms — with roles, workflows, and reports your team trusts.

Mobile apps

Cross-platform iOS & Android apps in Flutter and React Native, from first sketch to App Store and Play Store release.

No-code & low-code

Fast, scalable builds with FlutterFlow and Bubble — ideal for MVPs and internal tools, extended with custom code.

Websites & e-commerce

WordPress, WooCommerce, and fully custom-coded sites that are fast, editable, and built to convert.

Focus

Management systems of any type.

This is the work I enjoy most. If your organisation tracks people, stock, money, bookings, or tasks, I can turn the spreadsheets and paperwork into a clean system — with web dashboards for admins and mobile apps for the people on the ground.

We map your users, roles, and daily workflows — the real way work gets done.
02
Architect
I choose the right stack, design the data model, and agree on clear milestones.
