Currently leading design at Ruby Labs · ZenDocs

Design direction, grounded in data.

I'm Luka, a Product Design Lead with 8+ years across gaming, AI, healthcare, edtech and SaaS. I own design direction and sign-off across every product surface, govern the design system, and ground each major decision in the numbers.

How I work

Three things I bring to a design org.

Not a process deck, just the operating habits behind the outcomes above.

Data before pixels

Every major decision starts in the funnel, not in Figma. Mixpanel analysis and attribution data set the brief, define the hypothesis, and decide whether the work shipped or ships again.

Mixpanel · funnel analysis · attribution · A/B experimentation

Design system governance

One source of truth, actively owned. I hold direction and sign-off across surfaces so the system stays coherent as teams, tools and surfaces multiply, and handoff stops being a negotiation.

Direction & sign-off · design ops · handoff · cross-functional alignment

AI-augmented design

I encoded a full design system as an AI skill used org-wide, so the system authors work instead of just documenting it. Design infrastructure that compounds rather than decays.
