⚠️ Work keeps me busy, so my activity might be low. More active during holidays!Rest assured, I’ll respond to all messages as quickly as I can.
I firmly believe that tech stacks should be chosen based on actual needs, not just trends. Below is a breakdown of my expertise, categorized by the core scenarios I specialize in.
- Service:
FastAPI, I like asynchronous programming for better performance and scalability.
Pydantic, it helps me build reliable services.
MongoDB, it is better suited for JSON-based memory.
Redis, useful for caching hot data, request rate limiting, simple message queue (based on
Arq), and many other use cases.
- Agent-related:
LangChain (v1.0), Despite many criticizing its over-engineering, I still think it's very insightful.
- Qdrant, a practical vector DB with a concise Python API. I use it to build RAG pipelines, semantic-based search, and recommendation.
- Dify, to build isolated and simple requirements and integrate them into the Agent.
- Frontend:
Vue 3 (Composition API),
Vite,
Tailwind CSS,
XMarkdown
- Task Queue:
RabbitMQ (Distributed Message Broker)
