Dear Campspot Hiring Team,
I am applying for the Contract AI Developer role. I build AI-assisted, production TypeScript/React software — and I have already shipped a campground front-desk product that mirrors much of what Campspot operators do every day.
Why I fit the role
Campspot needs someone who can move fast with Claude Code, ship typed React features, and understand reservation workflows — not generic CRUD. That is how I work:
- Camp Desk (camping.fung-ai.com) is a live campground PMS I built solo: today's dashboard, booking grid, panorama site map, walk-in check-in, night audit, and guest ledger. The demo is open (no login) with English, Chinese, and Brazilian Portuguese — switch languages from the header to see the operator UI.
- Stack match: TypeScript, React 19, Next.js, REST-style server actions, async patterns, Vitest (65 tests), deployed on Cloudflare Workers with D1.
- AI-native workflow: I use Claude Code and agentic workflows daily for implementation, refactors, and test generation. At NSCC I lead third-party LLM security validation for Novastorms (OWASP LLM Top 10, structured test evidence). I also built an RAG routing bot PoC (ChromaDB + local LLM) for NSCC.
- Domain + quality discipline: In Shenzhen, I spent 8 years in software testing and 2 years in payment product management, operations, and project management — regression gates, audit trails, release sign-off in regulated systems, plus payment product launches and cross-team delivery. Camp Desk reflects that: ledger lines, night audit, audit log, and read-only demo mode are first-class, not afterthoughts.
Portfolio: fung-ai.com links Camp Desk alongside InnDesk (hotel PMS on the same architecture) and other shipped products.
Location and sponsorship
I am not yet resident in Brazil and would need employer support for work authorization to relocate. My preferred destinations are Vitória or São Paulo. I am used to remote, async delivery from Atlantic Canada and can align with your team's review and communication rhythm.
I would welcome a conversation about how Camp Desk maps to Campspot's roadmap — and where AI-assisted development can accelerate your next features. Thank you for your consideration.
Sincerely,
Feng Xiangyu
