Autopiter.ru is one of the largest auto parts marketplaces in Russia — 900K unique users and 5M+ monthly visits, with over 400 pickup locations. Historically a B2B platform, it was expanding into B2C and adding new product categories — aiming to become a full automotive marketplace.
I owned the entire design direction: web, mobile, personal accounts, supplier tools, new services. Not just the visual layer — the decisions about what to build, why, and in what order.

When I joined, two complaints kept coming from opposite sides.
Users were reporting poor contrast and readability across the site. The thin icon style and low-contrast palette made prolonged use uncomfortable — especially on data-heavy pages that wholesale customers spent hours in.
Development was frustrated that every interface element was essentially unique. Building anything new meant rebuilding from scratch — no shared components, no reusable patterns. Product work and visual fixes were competing for the same capacity.
These weren't separate problems. A design system could solve both — give development reusable blocks, and fix the visual foundation users were struggling with. That became my starting point.

The first thing I did was run a full contrast audit against WCAG 2.1 standards. The existing palette wasn't just aesthetically dated — it was actively making the product harder to use.
