Professional summary

Product design lead with 12 years across regulated B2B SaaS, fintech, esports and mobile, seven of them at one company, from UX/UI designer to Head of Design. I turn complex product logic into shipped software: strategy and information architecture, interaction design, design systems and front-end implementation with AI-assisted development that I direct and review.

Contract work since 2014 runs through VEKTOR (Grega Bulog s.p.), my sole-trader practice. The 2023 to 2025 contracts ran alongside my FirstBlood role as that platform wound down. Open to full-time and contract roles.

Experience

Product Designer & Design System Lead (Contract)

Nov 2025 – Present

BENS Consulting / Chemius · Slovenia, hybrid · Chemical-compliance SaaS · Design system

  • Designed and shipped a token-first Angular and Storybook design system: 69 governed components across four regulatory themes served from one library, replacing fragmented PrimeNG patterns through screen-by-screen adoption with no big-bang rewrite.
  • Own the tokens, motion rules, dense-data tables, accessible states and migration docs; direct Claude Code on the implementation and review every component before it ships.
  • Redesigned the technical-data-sheet editor from dialog-driven sections into a directly edited A4 canvas with a constrained block system, replacing templates engineering had hand-coded per customer; shipped into the existing platform ahead of the wider redesign.
  • Only designer on the wider redesign of Chemius (safety data sheets, labels, technical documents), deciding weekly with the CEO, the project manager, four engineers and two chemical consultants.

  • Only designer in a seven-person team (CEO, CTO, two engineers, a project manager, a co-founder); owned product design, brand, motion and the design system for a mobile opinion market.
  • Simplified onboarding and trading so wallets, gas, slippage and settlement stay out of the core flow.
  • A 10-day open testnet (February 2026) delivered 47% invite-to-signup conversion, 33% day-7 retention and 300+ daily active traders, averaging 4 to 6 sessions a week.

Apr 2023 – Jan 2025

Syyclops Inc. · Washington DC, hybrid · Enterprise SaaS, AI digital twin for facility management · Case study

  • Built the Figma design system (variables, components, states, icons) and the specs, motion documentation and prototypes engineering built the v1 web and iOS launch against.
  • Mentored the junior designer on the team.
  • During the engagement Syyclops deployed at Flint Hill School (two campuses, 350K+ sq ft) and a Hyatt Place hotel (2023) and piloted at Dunbar High School (300K sq ft) for DC public schools.
