Product design for the next layer of technology

Karda is a one-person product design studio for founders building hard things. I design the layer between your technology and the people who use it, from zero to one.

Manifesto

Technology, designed with intent, is the most powerful lever we have. But most of what gets built today is shaped by speed, hype, and short-term incentives.

The world needs fewer products, designed better. Products that respect the people operating them and the systems they run on.

Karda exists for this: a one-person studio working where design and technology meet, close to founders building real things.

If that's you, let's talk.

Work

Recent deep-tech product design work, across new space, robotics, telecom and AI. Case studies coming as projects ship.

Opus Aerospace website shown on a display above a camera slider rig.
Orange Livebox parental controls on Android — the household device list beside the scheduled-disconnection settings.
Nanoguild brand banner — the wordmark set among a cut-out robotic arm, a 3D-printer head and an experimental aircraft.

Services

Product design services for deep-tech founders, end to end: research, strategy, interface design, and the working build at the end of it.

Craft

  • Product Design

    Interfaces and systems built to hold up under real use.

  • User Research

    Interviews and tests that turn assumptions into evidence.

  • Product Strategy

    Positioning and the few moves that actually compound.

  • Prototyping

    Functional prototypes built fast. A working proof beats any deck.

Outputs

  • Website design & development
  • Software design
  • Investor decks
  • Design systems
  • Functional prototypes

7+ years shipping products used by millions of people. Trusted by leading companies in energy, telecom and entertainment. Now at work on yours.

Not sure where to start? Tell me what you're building.

  • Me, from the first call to the last file. Karda is a one-person studio: 7+ years of product design across telecom, energy and entertainment, on interfaces used by millions of people. No account manager in the middle, and no junior taking over once the contract is signed.

  • It starts with a 30-minute intro call. We talk through what you're building, where you are, and what you need. From there I scope the smallest engagement that moves you forward: a fixed project, or embedded work in your team. If neither fits yet, we start smaller, with a single landing page, a deck or an audit of your MVP.

  • A fixed project runs one to four weeks from kickoff to delivery, on a scope we agree before starting. Embedded work ships continuously, so you see progress every week rather than waiting on one big reveal.

  • Web and mobile apps, landing pages, MVPs, hardware prototypes, UX audits, and investor decks. If it's a product problem, from first concept to shipped build, it's likely in scope. If it isn't, I'll tell you on the call.

  • As much or as little as you like. Most founders want a weekly check-in and async updates in between. I work autonomously once the direction is set, and flag decisions that need you rather than blocking on them.

  • Fixed projects start at 9500€, with scope and price agreed before we start, so there are no hourly surprises. Embedded work is a monthly rate, set together on the intro call. Too early for either? Smaller first projects are possible, just ask.
