Hi, I'mMariusAdam.
- 5+ years experience

I build software that people enjoy using. I work across the whole stack, and lately a lot with AI, but the interface is where I put most of my care: making things feel fast, clear and easy to trust.
Teams I've worked with

About
Good software feels obvious. Getting it there rarely is, and that's the part of the job I love: the small calls on spacing, timing and wording that nobody notices when they're right.
I've spent most of my career on frontend and product work, and these days I'm just as often in the API, the data model or an AI feature. I like small teams, short feedback loops, and shipping things I'd want to use myself.
Outside of work I like reading about space now and then, which is where the astronaut comes from.
- 01
Interfaces that feel right
Layouts, interactions and motion that make a product easy to understand. I care about the in-between moments too: focus, loading and empty states, and the beat between a click and a result.

Product engineering
I'm happy to own a feature end to end, from a rough idea through API design and data modelling to the release, and to talk it through with designers and stakeholders along the way.
- 03
Applied AI
AI features that hold up in real use: grounded answers, sensible fallbacks, and interfaces that are honest about what the model is doing and how sure it is.

Things I've learned while building, mostly about interfaces. I write when I have something worth sharing.

Designing AI features people actually trust
Most AI features don't fail because the model is weak. They fail because people can't tell when to believe it. Here are the interface patterns I keep coming back to.

Why I keep reaching for GSAP
I first used it on a game launch years ago. It's still the animation library I enjoy most, and here's what I've learned along the way.

I rebuilt my portfolio and put an astronaut in it
What I learned making a personal site that's fun to scroll, from fake galaxies to a NASA spacesuit.
