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 maintain the component library that is the core product asset: more than 200 React components with props schemas, variants, and design constraints, organized into families and groups, curated and structured as a design system the whole 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 library, so generated pages carry a consistent, per-project 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. Encodes component-pairing judgment as a reusable rule instead of ad-hoc decisions.
• 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): a canvas-based sitemap interface of page nodes and their links, the generation/preview/editing UI, with WebSocket-based streaming of responses into the UI.
• Designed the code-export pipeline that ships a customer-owned, production-ready Next.js + Tailwind project (no vendor lock-in); published the @primeuicom/mcp server on NPM.
• Run code review and architecture discussions as daily routine; introduced Claude Code and Codex into the team workflow and built custom developer tooling on top (codex-bee, epic-loop).

International web consultancy for clients in the US, UK, Europe, and Australia.

• Architected the Tipico US backend on Sanity Headless CMS as a multi-tenant, white-label platform: white-label architecture for core and state teams, 5 publishing environments, 3 datasets. Operating scale: 122 CMS users, 75M requests/month, 98 document types, 165K stored documents.
• Designed and built CMS-KIT, an open-source Headless CMS starter and shared component library governed across 15 client projects and multiple teams, cutting kickoff from days to hours and accelerating development by ~30%.
• Led migration of 15 client projects to Headless CMS and commerce platforms (Sanity, Storyblok, Contentful, Payload, Shopify, Hydrogen), restructuring content models and cutting update cycles from weeks to days.
• Built the data-heavy analytics and reporting frontend for Porchlight (Compass real-estate platform, Next.js + tRPC): line-chart dashboards over market and area metrics (Chart.js, react-chartjs-2), interactive Mapbox GL maps with polygon-drawn geo-areas, and a PDF report pipeline where Puppeteer captures the rendered charts and @react-pdf/renderer assembles the document.
• Led technical hiring and team development: designed an assessment mirroring real working conditions, ran 30 interviews leading to 8 hires, mentored new engineers.

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

Built a fuzzy-logic search system and advanced UI animations for the corporate-services platform; configured the Webpack build.

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

Led an engineering team designing automation and control systems for dynamic architectural lighting (50+ installations).
