Hi, I’m Wesley.
Your developer.

Over 20 years of experience.
A personal approach.

Compivex is Wesley?s independent software development and consulting business. I build websites, mobile apps and custom software, connect business tools, and review application security.

I started programming at 14. More than 20 years later, I help individuals and businesses turn ideas into websites, apps, and software that fits the way they work.

Tools change. Understanding the code still matters. I use modern tools, including AI where it helps, and take pride in the software I build and responsibility for what I deliver. That means thoughtful architecture, code I understand and test, and systems designed to stay maintainable and scale as your needs grow.

You’ll work directly with me, from the first conversation to launch. An experienced developer who can explain the decisions, solve the difficult problems, and help you take the next step.

Before we get started

What can Compivex build for me?

Compivex builds business websites, online shops, web applications, customer portals, iOS and Android apps, and custom business software. I also connect existing tools, automate workflows and build data collection tools.

Who will I work with?

You work directly with Wesley, an independent developer with over 20 years of programming experience. I handle the technical decisions and work with you from the first conversation through testing, launch and handover.

Can you improve or review existing software?

Yes. I help with performance, scalability, integrations and maintainability, as well as code security reviews and application or infrastructure penetration testing. We agree the scope before work starts; assessments include prioritised findings and practical recommendations.

Do I need a technical brief, and how is the project priced?

A rough idea is enough to start. Tell me what you want to achieve, who the software is for and which tools you already use. After discussing your needs, I provide a scope, estimate and delivery plan. Support is agreed as part of the handover.

Have something in mind?

Let’s talk.

A rough idea is enough.
We can figure out the rest together.

Tell me what you have in mind. I’ll reply personally with questions, possible approaches, and a sensible next step.

No commitment required.
