Off-the-shelf software rarely fits the way your business actually works. A custom web app can: a booking tool, a client portal, an internal dashboard or a whole online product. I design it around your users first, then build it with modern, well-supported tools.

What I build#

  • Dashboards and admin panels that turn data into clear screens.
  • Client portals and member areas with secure logins.
  • Booking and scheduling tools.
  • Front ends for existing APIs and back-end systems.
  • Prototypes and first versions (MVPs) to test an idea before you invest more.

How a web app project works#

  1. Discovery. We agree on who the users are, what they need to do and which features come first.
  2. Design. I design the key screens in Figma and link them into a clickable prototype.
  3. Build. I build it in React or Angular with reusable components, connected to your API or back end.
  4. Testing. I test it across browsers and devices, then fix issues before launch.
  5. Launch and support. It goes live, and I’m on hand for changes and new features.

React or Angular?#

Both are proven and widely used. React suits fast-moving products and teams that want flexibility, while Angular suits larger apps that benefit from a strict structure. If you already have developers, I’ll work with whatever they use.

Need the interface designed first? See UI/UX design. Already have it in Figma? See Figma to React.

I’m based in Melbourne, Australia, and I work with clients in Australia, the US, the UK and around the world. Because everything runs through Fiverr, your time zone doesn’t matter: messages, files and payments stay in one place, and payment is only released to me when your order is complete.

Common questions#

Can you work with my existing back end or API?#

Yes. I can build a new front end for your API, or work with your developers on both sides.

Who owns the code?#

You do. When the order is complete, the code and the design files are yours.

Can we start with a small version?#

Yes. Starting with a simple first version is often the smartest way to test an idea and learn what users really need.

“Really happy with this order. I needed a custom header built in React based on my own design, and the result matched it perfectly. Every detail was followed just as I requested. The code is clean and the header looks and works great. Clear understanding of the requirements and a truly excellent job overall…”
