Portrait of Tom Cardoen

Tom Cardoen · Software Engineer · Liège, BE

I design and build software.
Lately: smart batteries.

At Azimut I build the apps for our smart home batteries. Outside work I ship my own things: seal, a secret-sharer. And through Nodeo, I help others ship theirs.

Azimut

Software Engineer

I build the software around the battery: the part that makes a home’s energy readable at a glance, and turns an installer’s setup from an afternoon into a few minutes.

HELMo

BSc, Application Development

Graduated with distinction. Liège.

02 / Studio

Nodeo · freelance, since Oct 2024

Freelancing, with nodeo.be. I take founders and small teams from idea to shipped product: web and mobile, design and build, one person you actually talk to.

Things I build for fun

My corner for tinkering with stuff, no pressure. Every so often one turns into a real project.

seal

One-time secret sharing, end-to-end encrypted: the server never sees the message.

04 / Notes

What I keep coming back to

01

I learn by building. My GitHub is full of prototypes: an evolution simulator, a memory game, piles of little tools. Each one taught me something, even the ones I never finished.

02

I won’t choose between design and code. I’d rather move between the Figma file and the codebase all day than be great at only one. Most of the good stuff is in the back-and-forth.

03

I don’t trust software that asks for too much. I built seal so the server can’t read your messages, half to prove I could, half because most apps hoard data they don’t need.
