Hi. I'm Gaëtan.

I am an experienced software engineer and full-stack developer from Belgium.

I create value through code, process, and AI.

Get to know me

What I do

1

I build software

Shipping for impact.

Web apps, APIs, integrations and the cloud infrastructure under them. From a proof-of-concept to an architecture in production, or picking up an existing codebase and making it dependable again. Always with cost and scale in mind.

2

I optimise processes

Engineering that fits the business.

I look at where your organisation is going and shape the engineering to match: an architecture that fits your size, agentic practices that keep quality up, a deployment strategy that does not get in the way, and stakeholders in the same room.

3

I put AI to work

In your product and in your team.

I have built features where language models answer questions over data and documents, turn messy input into structured data, and automate what used to need a person. For teams, I set up AI-assisted development that makes them more efficient.

About me

I have been professionally building software since 2012: delivering SaaS platforms, leading development teams, and shipping complex projects to production.

Since 2024 I work independently, offering years of expertise in backend, frontend, cloud and delivery. When you work with me, I will be the human between you and the software: someone who understands your problem and feels responsible for the result. I like to think through your business and your long-term strategy with you before I write a line of code.

Naturally, AI is part of how I work, both in my own workflow and in what I deliver. Whatever the tools, my software follows a few values I do not compromise on: it scales along with your operations, it is cost efficient to run, and it is secure by design. I can hold to those because I understand how software works under the hood, which lets me move between stacks and adapt to what your project needs.

If you have something to build, or something that should run smoother, tell me about it. I am always up for a coffee, virtual or real.

Selected work

A short selection from a much longer list. Pick a project to read what the problem was, what I did, and how it turned out.

Cheqroom2024 to now

Leading engineer in an asset-operations SaaS team

Problem. Cheqroom is the worldwide number one asset management tool for AV and tech gear. A growing customer base needed more flexible operations flows, tighter security and a faster engineering team.

What I did. I joined the engineering team in 2024 and grew into one of its leading engineers within two years. I implement the more complex features, such as configurable operations workflows tailored per customer. I hold the security champion role and own the infrastructure. And I drive the team's efficiency forward by introducing agentic engineering practices.

Outcome. A more configurable product, a hardened platform, and a team that ships faster with the same people.

Tell me about your project.

A new product, a backend nobody dares to touch, or an idea you want a second opinion on. Write me a few lines and we take it from there.
