Summary
Senior Node.js / TypeScript backend engineer and Tech Lead with 9 years of production
experience, currently leading the backend and AI generation layer of PrimeUI
(primeui.com, launched Feb 2026): an AI-native
"vibe coding" platform that ships customer-owned Next.js projects. Designed and operated
consumer-scale backends on PostgreSQL and the Sanity-based Tipico US platform (75M
requests/month, 122 CMS users). Comfortable owning services end-to-end: REST API design,
database modeling and optimization, performance tuning, third-party integrations, and
AI/LLM orchestration as a first-class backend concern.
Skills
Backend & APIs: TypeScript, Node.js, REST APIs, WebSockets, GraphQL. PostgreSQL, Drizzle ORM, SQL design and query optimization. Schema validation, retry/recovery, streaming responses. Public-API design for cross-host integrations (MCP server, CLI)
AI Engineering: LLM orchestration and guardrails on the backend: multi-model routing (Claude / GPT / Gemini), context engineering, prompt caching (73% Gemini context-cache hit rate), schema validation, retry recovery. Embeddings-based retrieval. MCP: custom server development; cross-host agent integration
Infrastructure & Delivery: Docker, docker-compose. Vercel, Cloudflare, Serverless & Edge functions. CI/CD pipelines, NPM package publishing. Web performance: Core Web Vitals, Lighthouse, WCAG
Full-Stack adjacent: React, Next.js (App Router, SSR/SSG/ISR), TanStack Start/Router, Vite, Tailwind, shadcn-style design systems. Headless CMS: Sanity, Storyblok, Contentful, Payload

Feb 2025 – Present
PrimeUI (primeui.com, launched Feb 2026) is an
AI-native platform for generating production-ready websites, spanning Studio web app,
public API, MCP server, CLI, and code-export pipeline. Sole full-time engineer on the
project, owning roughly 70% of platform architecture across all surfaces.
- Architected the AI generation layer on the Node.js backend: multi-model orchestration via Mastra + Vercel AI SDK (10 agents, 17 workflows) with per-task routing across Claude, GPT, and Gemini; embeddings-based component retrieval over 1,555 chunks (OpenAI
text-embedding-3-small) with three-tier fallback from exact key to family bucket to semantic search; prompt caching reaching 73% Gemini context-cache hit rate.
- Public API, code-export pipeline, and CLI: generates a production-ready Next.js project repo in ~45 seconds, ~1.5 minutes end-to-end from UI Export to a running local project. The generated codebase is customer-owned, shipped as a standard Next.js project, pre-configured for 8 selectable AI coding agents.
- Built and published
@primeuicom/mcp on NPM: 25 tools that let any external codebase connect to PrimeUI from inside AI coding environments, with cross-host compatibility verified across 6 major coding agents (Claude Code, Cursor, Codex, others).
- Owned the Node.js server runtime end-to-end, including WebSocket-based streaming of model responses adapted to UI rendering, schema validation, retry and recovery flows for LLM calls, and third-party API integrations.
- Drove team AI-tooling adoption: Claude Code from project start, team transition to Codex ahead of public release. Open-sourced codex-bee and epic-loop as spinoffs.

International web consultancy for clients in the US, UK, Europe, and Australia.
- Architected the Tipico US backend on Sanity Headless CMS at consumer scale: 75M requests/month, 122 CMS users, 98 document types, 165K stored documents. 5 publishing environments, 3 datasets, white-label architecture for core + state teams.
- Built a Claude-based content automation pipeline: JSON translation flow for 190 country-specific Storyblok pages, integrated into publishing and saving ~1 month of manual work.
- 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.
- 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; drove team adoption of Claude.ai for research, content, and codebase analysis from 2024 onwards.
