Interface Engineering
React and TypeScript applications built to survive their second year: predictable state, honest component APIs, and tests that fail for real reasons.

Interfaces that are fast, accessible and quietly exact.

01Approach
I build the web the way it should feel — fast, quiet, exact.
Most of what makes an interface good is invisible: the request that never fires, the layout that never shifts, the focus ring that lands exactly where your hand expects it. I spend my time there. The visible part — the type, the motion, the restraint — is what is left once the invisible part is right.
03Capabilities
What I actually do all day
Motion & Interaction
Scroll choreography, page transitions and micro-interaction detail — implemented on transform and opacity only, so the frame budget stays intact.
Performance
Core Web Vitals treated as a design constraint from the first commit. Bundle budgets, font subsetting, image pipelines, and real-device profiling.
Accessibility
WCAG 2.2 AA as a floor, not a target. Keyboard-first flows, sensible focus order, screen-reader passes, and reduced-motion paths that are genuinely equivalent.
Design Systems
Token architecture, component documentation and the governance around it — the part that decides whether a system is used or quietly abandoned.
Architecture & Delivery
Vite build pipelines, CI that catches regressions before review, and deployments boring enough to run on a Friday afternoon.
04About
Good software feels like nothing at all. That absence is the whole craft.
I am a web developer based in Zagreb, working with studios, cultural institutions and product teams who care how a thing is made. Seven years in, mostly front-end, increasingly the parts of the back-end that decide whether the front-end can be fast.
I like briefs with a real constraint in them — a museum tablet from 2014, an editor who ships at midnight, a warehouse with no signal. Constraints are where the interesting decisions live.
