Nejc Končan — UI/UX Designer & Software Engineer, Ljubljana Full-stack developer at PIARA ↗

DESIGN. BUILD. SHIP.

I design interfaces and engineer the products behind them — web, mobile & desktop apps taken from first wireframe to production deploy. Currently building AI-native products.

Selected work

I'm a designer who writes production code — and an engineer who cares how it feels. One person, the whole pipeline: research, interface design, motion, frontend, backend, databases, AI pipelines and cloud infra. No hand-offs, no lost intent.

How it ships
  1. 01

    Discover

    Goals, users, constraints, competitive teardown. The problem gets defined sharper than the brief.

  2. 02

    Design

    Flows, wireframes, a design system with tokens, a motion language. Prototypes that feel real enough to argue with.

  3. 03

    Build

    Production code from day one — typed, tested, reviewed. Because the designer is the engineer, intent survives the build.

  4. 04

    Ship

    CI/CD, monitoring, analytics, store releases. Then iterate — shipping is the starting line, not the finish.

Just because
Nothing mocked

This page is its own case study.

Zero frameworks, zero templates — hand-written HTML, CSS, GLSL and vanilla JS. The terminal works. The numbers are measured on your device, right now.
