About Kai
Full-Stack Dev | Ship Your Idea as Working MVP in 1-2 Weeks
Tangshan, China - 12:33 pm local time
I'm a full-stack developer with 5+ years of experience. Since 2023, I've been shipping products using AI-native workflows (Cursor,
Claude Code, GPT-powered development) — from the very start of the vibecoding wave. While most developers are still exploring how to
integrate AI into their process, I've already shipped multiple production apps this way, which is why I can turn your idea into a
working MVP in 1-2 weeks, not 1-2 months.
What I can build for you:
- Complete MVP (frontend + backend + deployment) for SaaS or AI products
- Cross-platform desktop app using Tauri (Rust + web tech)
- Clean, production-ready Python API with FastAPI
- AI integration: OpenAI, Claude, local LLMs, image and music generation
Cross-stack flexibility — I use the right tool for your problem, not my comfort zone:
React · Next.js · TypeScript · Python · FastAPI · Tauri · Rust
Recent projects I shipped:
- BeatCraft — AI music generation platform, live and serving international users
- TermCanvas — Multi-terminal canvas manager (Tauri desktop app)
- Memory Forge — AI conversation management tool (open source)
How I work with clients:
- Written progress updates every 24-48 hours with screenshots and code pushed to your repo
- Async-first communication — no timezone headaches, no unnecessary meetings
- AI-augmented workflow means faster iteration and lower cost for you
If you have an idea that needs to become real, working code in the next 2 weeks, send me a message describing what you want to build.
