Roman Polyarush

Senior product designer with 15+ years shaping financial products, SaaS, and design systems. I work from the problem, not the screen — turning briefs and business goals into interfaces that ship, scale, and hold up in production. Equally comfortable owning a design system and the hands-on craft, from Figma components to AI-generated imagery and video.

Senior product designer (UI/UX) & design manager at Themerex (2016-01 – Present)

Company runs three active brands (ThemeREX, AncoraThemes, AxiomThemes) with 360,000+ total sales - a structure close to supporting multiple B2C/B2B product lines in parallel, each needing its own visual identity within a shared system.

• Built a 600+ block design system - reusable components, shared design tokens (spacing, typography, color schemes), and a designer checklist - that lets the team ship new, visually distinct releases quickly across three product lines without breaking consistency. An in-house plugin carries these tokens across projects and flags layouts that drift from the rules, cutting rework and speeding up developer handoff.
• Designed and shipped a high volume of production releases from structured briefs (Jira tickets), as one of 7 designers on the team - personally leading design on dozens of releases that collectively sold 300,000+ copies across e-commerce, medical, fitness, real estate, and corporate niches, including Elementra, the group's flagship product (4,500+ sales).
• Owned the visual and content layer of every release: created custom imagery and video with AI (Midjourney, Kling, Veo, Nano Banana Pro) or pulled from premium stock, researched each niche, and wrote placeholder copy - so every page felt like a real, finished product rather than a reused template.
• Partnered closely with developers and QA: ran design reviews, handed off specs, and checked the coded build against the original Figma to catch mismatches before release.
