About

A one-person studio. A long memory.

Helsh-js is a one-person product studio. I have been on both sides of the agency table, and I have designed this place to be the kind of partner I wished I could have hired ten years ago.

Founded
2019
Based
Belgium, EU
Hands on deck
One. Mine.
Working hours
Belgium time (UTC+1 / UTC+2). No graveyards.

I started Helsh-js in 2019, after a few too many conversations with founders who had been burned by agencies. The pattern was always the same. A charismatic salesperson, an inspiring pitch deck, and a slow drift into "we'll have to circle back on that" while the actual code was being written by someone who had been hired three weeks earlier.

I thought I could do better by doing less. The person on the call is the person writing the code. One person on purpose, small enough that I know the state of every project.

I work across mobile, web, and infrastructure. Analysis, design, front-end, back-end, the unglamorous plumbing that makes it all run. The last few years have been a lot of AI-augmented products, integrations with the systems businesses already run, and custom work that does not fit a template. You can see the results of my ongoing contract with Eagl and of Felix, a product of my own. I only ever show the result. The code and the data belong to the customer.

I am based in Belgium and work on Belgium time (UTC+1 / UTC+2). I sign NDAs gladly. I charge fairly. I turn work down when I should.

What I believe

Five things I keep stuck to the wall.

Show, don't say.

A working demo beats a slide deck. I show you working software as early as I can.

Short loops.

I would rather find out I am wrong early than late. Plans are working documents and I update them out loud.

Boring tech, sharp judgement.

I pick technology that will still be a sensible default in five years. Excitement belongs in the product, not the stack.

Quiet professionalism.

I talk about a release once it is live, and I finish what I start.

Receipts.

I document. I hand over keys. You should never feel locked in to me. The best clients hire me again because they want to, not because they have to.

Sound like a fit?

The easiest way to reach me is the contact form, or a plain old email.
