PrimeUI (<a href="https://primeui.com/">primeui.com</a>, 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.
|
||
</p>
|
||
<ul>
|
||
<li><strong>End-to-end full-stack ownership across the platform</strong>: 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.</li>
|
||
<li><strong>Designed and shipped the code-export pipeline and CLI</strong>: 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.</li>
|
||
<li><strong>Built and published MCP server</strong>: 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).</li>
|
||
<li><strong>Cut client-wireframe turnaround at PixelPoint</strong> from a week of Figma prototyping to a few hours: deployed responsive prototypes with production-level performance and dynamic interactions instead of static mockups.</li>
|
||
<li><strong>Architected the generation layer with secure multi-provider LLM integration</strong>: 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.</li>
|
||
<li><strong>Mentored the team on modern AI-augmented development workflow</strong> from project start, including transition to Codex ahead of public release. Open-sourced two CLI tools built in the process (codex-bee, epic-loop).</li>
