I've been a developer for 13 years, and I founded LunaLab, a studio that takes web, mobile and backend products from planning and design through development, launch and operation.

I don't make a claim without a measurement behind it. I write the limits down before anyone has to ask, and I keep a test that fails the day a claim stops being true.

Open source

• flutter-ux-journey: a journey-level UX audit for Flutter apps. It measures a running app: real pixel rects, real contrast ratios and real semantics labels.
• qr-contact: a business-card QR generator (vCard 3.0, PNG/SVG). It runs entirely in the browser, and no data leaves the device.

Work with me

• Hire the studio. I build Flutter apps, web services, backends and MVPs. You get a fixed quote for the agreed scope and no extra charges inside it. I care as much at handover as I did at kickoff.
• Hire me. Full-time offers are very welcome. I work best remote, and for the right role I'm glad to relocate and work from the office.
