About Dahu
Senior Full-Stack AI Engineer | Next.js, LLM Agents, Scalable MVPs
Beijing, China - 7:14 am local time
I’m a senior full-stack developer with 18+ years of hands-on experience building and evolving real-world systems — from early MVPs to scalable, user-facing platforms.
I work best with teams that want to move fast without cutting corners. I believe in building something simple first, but with the right technical foundations so it doesn’t need to be rewritten a few months later.
Clients usually come to me for:
Zero-to-One MVP Building: Taking products from concept or prototype to a solid, launch-ready first version.
Modern Web Apps: Developing high-performance full-stack applications with Next.js, React, and TypeScript.
Practical AI Integration: Adding smart features (OpenAI APIs, LLMs, agent-style automated workflows) in a product-focused way, not just as gimmicks.
Scalable Architecture: Designing backend systems and databases (like Supabase/PostgreSQL) that support async workflows and future scale.
Technical Leadership: Making clear technical decisions when trade-offs aren’t obvious.
I’m comfortable owning features end-to-end — from shaping scope and database architecture to writing production-ready code and shipping it.
My Core Tech Stack:
Frontend: Next.js, React, TypeScript, Tailwind CSS
Backend & DB: Node.js, Supabase, PostgreSQL (plus Java/PHP legacy experience when needed)
AI & Automation: OpenAI APIs, LLM Workflows, Prompt Engineering
Mobile: Flutter
Cloud & Deployment: Vercel, AWS
I value clear communication, realistic timelines, and code that’s easy to maintain. I don’t over-engineer MVPs, but I also don’t build throwaway prototypes.
If you’re starting a new product or looking for a reliable engineer to build your next AI feature, feel free to reach out — I’m happy to take a look and discuss the best next steps.
