Dade Sheng
AI Solutions Architect
I design production agent systems — multi-provider LLM gateways, MCP and A2A surfaces, and scheduled agent fleets — and ship React/TypeScript products on AWS serverless. A Toptal developer since 2020 with years at Amazon, I help teams go from chatbot demos to reliable AI platforms: model routing, tool design, and cloud delivery. I work daily with Claude Code, Cursor, and specialist agents.
What I Do
Production Agent Systems
⚡ Design production agent systems: tool surfaces, knowledge access, and scheduled agent fleets
⚡ Use MCP as a control plane so agents can reach tools and knowledge without one-off glue
⚡ Shape A2A-style agent collaboration and Google ADK-style platforms at an architecture level
⚡ Work daily with Claude Code, Cursor, and specialist coding-agent fleets on cloud workstations
LLM Gateways & Model Routing
⚡ Design multi-provider LLM gateways: routing, virtual keys, and spend budgets
⚡ Help teams move from chatbot demos to reliable AI platforms — model routing, tool design, and failover
⚡ Keep provider choice a platform decision, not a rewrite, across Claude, GPT, Gemini, and others
⚡ Ship the gateway next to the product so routing, auth, and cloud delivery stay one system
Cloud Infra & AWS Serverless
⚡ Years at Amazon and AWS shipping global cloud products on serverless infrastructure
⚡ Host and run production sites on AWS; serverless with API Gateway, Lambda, and DynamoDB
⚡ Auth and identity with Amazon Cognito, AWS Amplify, and AWS AppSync
⚡ Data pipelines on Spark/EMR and migrations off large legacy databases — the delivery layer under AI platforms
Full-Stack Engineering
⚡ Ship React and TypeScript products end to end, with Node backends and Postgres
⚡ A Toptal developer since 2020 — product engineering from healthcare tools to cloud consoles
⚡ Containerize and deploy with Docker; comfortable across web, APIs, and mobile surfaces
⚡ Care about the interface people use, not only the agent behind it
