PrimeUI (primeui.com, launched Feb 2026) is a multi-surface platform that turns a sitemap and product brief into production-ready websites. It spans a Studio web app, public API, MCP server, CLI, and code-export pipeline. Lead developer, owning ~70% of platform architecture across all surfaces.

• End-to-end full-stack ownership across the platform: Studio web app (TanStack Start, React, TypeScript), Node.js server runtime with PostgreSQL and Drizzle ORM, Dockerized staging and production deployment, public API, MCP server, CLI, code-export pipeline, and component registry.
• Designed and shipped the code-export pipeline and CLI: generates a production-ready Next.js project repo in ~45 sec and ~1.5 min end-to-end from UI Export to a running local project. The generated codebase is fully owned by the customer (no vendor lock-in) and shipped as a standard Next.js project.
• Built and published MCP server: 25 tools letting any external codebase connect to PrimeUI as a third-party integration; cross-host compatibility verified across 6 major coding environments (Claude Code, Cursor, Codex, others).
• Cut client-wireframe turnaround at PixelPoint from a week of Figma prototyping to a few hours: deployed responsive prototypes with production-level performance and dynamic interactions instead of static mockups.
• Architected the generation layer with secure multi-provider LLM integration: multi-model orchestration via Mastra + Vercel AI SDK (10 agents, 17 workflows), per-task routing across Claude / GPT / Gemini with auth and data handling for each provider, schema validation with retry recovery, prompt caching (73% Gemini context-cache hit rate), and WebSocket-based streaming of model responses to the UI.
• Mentored the team on modern AI-augmented development workflow from project start, including transition to Codex ahead of public release. Open-sourced two CLI tools built in the process (codex-bee, epic-loop).

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

• Architected the multi-tenant Tipico US backend on Sanity Headless CMS: 5 publishing environments, 3 datasets, white-label architecture for core + state teams. Production scale: 122 CMS users, 75M+ requests/month, 98 document types, 165K+ stored documents.
• Led migration of 15+ client projects to Headless CMS and commerce platforms (Sanity, Storyblok, Contentful, Payload, Crystallize, Shopify, Hydrogen), restructuring content models and cutting update cycles from weeks to days.
• Built an LLM-based content translation pipeline: JSON translation flow for 190 country-specific Storyblok pages, integrated into the publishing process and saving ~1 month of manual work.
• Designed and built CMS-KIT, an open-source Headless CMS starter and component library used across 15+ client projects, cutting kickoff from days to hours and accelerating development by ~30%.
• Led technical hiring and team development: designed an assessment mirroring real working conditions, ran 30+ interviews leading to 8 hires, mentored new engineers and reviewed their architectural decisions.

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 between car owners and lessees.
