PrimeUI (primeui.com, launched Feb 2026) is a multi-surface platform that generates production-ready websites from a curated React component library. Lead developer owning ~70% of platform architecture, with the component library, the design system, and the component-based page generation pipeline as my core areas.

• Built and maintained the component library that is the core product asset: 200+ React components with props schemas, variants, and design constraints, organized into families and groups. Curated and structured it as a design system that the rest of the platform builds on.
• Built the design-system tooling: an internal tool to define a project's visual identity (colors, typography, design tokens) and apply it across the component library, so generated pages carry a consistent theme.
• Built a component-matching scoring model that evaluates how well adjacent components fit together: it compares their layouts, entry and exit widths, and component format, and produces a combinability score that ranks candidate compositions.
• Set up the page generation pipeline: composes components from the registry into full responsive pages, validating each against the component's props schema with retry recovery, then renders and previews before export.
• Own the Studio web app frontend (TanStack Start, React, TypeScript): canvas-based sitemap interface, generation/preview/editing UI, with WebSocket-based streaming of responses into the UI.
• Designed the code-export pipeline: generates a customer-owned, production-ready Next.js + Tailwind project (no vendor lock-in) in ~45 sec, ~1.5 min end-to-end. Also built and published the @primeuicom/mcp server on NPM (25 tools, verified across 6 coding agents).
• Run code review and architecture discussions as daily routine; introduced Claude Code and Codex into team workflow, built custom developer tooling on top (codex-bee, epic-loop).

International web consultancy for clients in the US, UK, Europe, and Australia. Shipped 15 production Next.js / React applications with TypeScript, Redux Toolkit and RTK Query, headless CMS, and serverless/edge backends.

• Built and maintained shared component libraries and design systems across client projects, working component-driven with Storybook, theming, and localization. Shipped CMS-KIT, an open-source Headless CMS starter and component library reused across 15 projects, cutting kickoff from days to hours and accelerating development by ~30%.
• Owned frontend performance and accessibility: optimized client applications for Core Web Vitals, ran bundle analysis and render optimization, and brought pages to WCAG accessibility standards.
• Built the frontend for MarketFinance (case study), a fintech lending platform, and other consumer-facing products across regulated and high-traffic domains.
• Architected the Tipico US backend on Sanity Headless CMS: 5 publishing environments, 3 datasets, white-label architecture. Operating scale: 122 CMS users, 75M requests/month, 98 document types, 165K stored documents.
• Integrated REST and GraphQL APIs with generated typings across projects; authored a comparison of headless GraphQL APIs on the FocusReactive blog.
• Led technical hiring and team development: designed an assessment mirroring real working conditions, ran 30 interviews leading to 8 hires, mentored new engineers; introduced error monitoring (Sentry) and code-review practices.

Built publishing flow via Slack API and a reusable web framework for conference websites; migrated GitNation conferences to Headless CMS.

Built fuzzy-logic search system and advanced UI animations for the corporate-services platform.

B2B marketplace for Skolkovo Innovation Center (100 companies); GraphQL subscriptions for real-time chat.
