You will get a production-ready AI feature integrated into your existing SaaS
Project details
Add one focused AI capability to your existing SaaS without turning the codebase into a disposable demo. I will integrate a clearly defined AI feature into your product, covering the agreed backend API, frontend experience, data flow, error handling, configuration, tests, and deployment support.
With 20+ years in software development, I combine hands-on full-stack implementation with system architecture and 0-to-1 product experience. I work across TypeScript, React, Next.js, Node.js, Python, FastAPI, PostgreSQL, Supabase, Docker, cloud platforms, and leading LLM APIs.
The packages are intentionally scoped: Starter covers one backend integration; Standard delivers a complete frontend-and-backend feature; Advanced covers a production workflow with deployment, monitoring, documentation, and handoff. We will confirm acceptance criteria before work begins. If your request is broader than one feature, I will identify it early and recommend a custom contract instead of hiding scope risk.

About Jerry
Senior Full-Stack AI & SaaS Developer | MVP to Production
Hangzhou, China - 3:03 pm local time
With 20+ years in software development, I combine hands-on 0-to-1 product building with experience leading large-scale production systems. You work with one senior developer who can see the whole product, make pragmatic tradeoffs, and ship maintainable software.
What I can help you build:
• SaaS MVPs and complete web applications
• AI-assisted SaaS features and hosted LLM API integrations
• APIs, admin dashboards, subscriptions, billing, and multi-tenant systems
• Scalable backend architecture and database design
• Existing-product modernization, performance, and reliability improvements
Selected experience:
• Built Amazing Chinese, an AI-powered Chinese learning platform, end to end
• Built Echoling, an AI-assisted spoken-English practice product
• Led a next-generation VAS platform at Tuya Smart supporting transactions, provisioning, metering, and billing for 100+ internal services
• Co-founded and architected a K-12 learning platform adopted by thousands of schools
Core stack:
TypeScript, React, Next.js, Node.js, Python, FastAPI, Java, PostgreSQL, MySQL, Supabase, Redis, Kafka, Docker, Cloudflare, and Vercel.
I focus on usable products, clean architecture, honest communication, and measurable delivery—not disposable demos. Share your goal, current stage, and constraints, and I’ll help identify the shortest responsible path to launch.
