Work Process

I build 4D applications that businesses rely on every day, from point-of-sale and document management to healthcare and government systems. I also help companies modernize those systems, bridging what already works with modern 4D, web interfaces, and AI, without disrupting the business along the way.

1. Discover

I start by learning your goals, your audience, and your constraints through a short call, and I review what you already have in place so we build on what works.

You get: A clear project brief

2. Design

I map out the structure, screens, and data flow, then craft the visual design and an interactive prototype for your feedback.

You get: A design you approve before any code is written

3. Develop

I turn the approved design into clean, reliable code, from responsive interfaces to the data behind them, tested across devices.

You get: A working version to test and review before final delivery

4. Deploy & Refine

I handle testing and deployment, then check performance and gather feedback to polish after go-live.

You get: Your project deployed, with post-launch support

How I Can Help

Many businesses run on systems that still work but have fallen behind their tools. I start by reviewing what you have and recommending the right path, then help you bring it up to date, with a particular depth in 4D, and get your team confident working with it, without disrupting the business in the process.

Discuss Your Project

Consultancy & System Review

I take a close look at your current systems, whether a database, an in-house tool, or a web application, then recommend the right path forward. That might be an upgrade, a rebuild, or leaving what works alone.

4D Upgrades & Conversion

Moving your application from an older 4D version to a current one, with your data, structures, and code carried across and tested before anyone switches over.

Classic to ORDA Transition

Reworking classic 4D code to ORDA step by step, so you get cleaner, more maintainable code and a path to web integration, without a risky big-bang rewrite.

4D Developer Mentoring

Practical, one-on-one guidance for your developers, from the 4D language fundamentals to modern ORDA practice, drawn from real project experience so your team can own and extend the system themselves.

Happy Clients
