Front-end engineer · Design & UX · Est. 2013
Software, carefully cultivated.
I'm a front-end engineer with a designer's eye. I build fast, accessible interfaces in React and TypeScript, and the backend to run them when a project needs it. Design is where I started, so I care how the whole thing feels, not just how it works.

Three disciplines, one gardener
front-end at the centre, design in the roots, backend within reach

Front-end engineering
The part people actually touch: fast, accessible interfaces built in React and TypeScript, with clean, maintainable code and design systems that hold up as they grow.
the visible growth
Design & UX
Where I started, over a decade ago. A real design and illustration background means interfaces judged by how they're used, not how they demo, and an eye for the details that make software feel considered.
where I first grew
Backend when it's needed
When a project needs the whole thing, I build the APIs and systems behind the front-end too, so I can take an app from idea to something running, on my own.

The method
how I work, in four seasons
Frame
Work out the real problem, the constraints, and what success looks like, before any code is written.
Shape
Plan the build and choose the right tools for it. Every decision is written down, so nothing is a black box.
Build
Build in short cycles, front-end first, with working software to see early and often.
Launch
Ship it. What's left is clean, documented code a team can own outright, or I stay on to keep building.

Pressed & kept
kind words from people I've worked with
At Mention Me we worked with Constantin for a few years and were constantly impressed both by the quality and promptness of his output. He was always willing to go out of his way to make sure we (and our clients) got a great finished product.
Having worked with Constantin for a few years, we can safely say that we are impressed and satisfied; he is thorough and knowledgeable and he always had our company's interests in mind when delivering.
Constantin was a real pleasure to work with and we look forward to working with him again. He's definitely the kind of professional you can trust with a project from start to finish.
