Skills

Core capabilities across RAG, agents, Python backend development, enterprise Java development, and cross-stack engineering.

RAG & AI Application Engineering

Builds RAG / Agent applications with Python, LangChain, and LangGraph, covering PDF / HTML parsing, text chunking, embeddings, Chroma, hybrid BM25 and vector retrieval, RRF, and citations. Uses LLMs for structured query planning and improves recall through source grouping, candidate quotas, and backfilling, with versioned Hit@K and MRR evaluation and Cross-Encoder reranking comparisons. Experienced with tool calling, structured output, context management, Redis caching, fallback handling, and safety controls before and after model calls.

AI Coding & Agent Collaboration

Extensive experience using AI coding agents including Codex and Cursor to organize cross-stack development, troubleshooting, documentation, and deployment verification through requirement decomposition, project rules, staged implementation, and testing and acceptance. Has used DeepSeek, GLM, GPT, and related APIs, with hands-on experience deploying Hermes Agent, integrating instant messaging, monitoring markets, running simulated trades, and connecting live-trading APIs.

Java & Backend Engineering

Has Java development experience at TRS and Spring Boot project experience using Spring Cloud, MySQL, Redis, and RESTful APIs. Contributed to public-opinion data processing and filtering, completed the full 99Bill payment integration flow, and worked on CRM access isolation, data management, and API integration with Spring Boot, MySQL, and Redis. Can use AI Coding to quickly understand existing Java codebases and deliver requirements, APIs, debugging, and features.

Web3 & Cross-Stack Practice

Hands-on experience developing Solidity smart contracts and DApps with React, Next.js, and TypeScript, using Foundry / Hardhat for contract development and testing and RainbowKit, Wagmi, and Viem for wallet integration, contract reads and writes, and transaction signing. Deployed and launched multiple DApps and won first prize at the Reactive Network AI Hackathon with FlashBack. Passed CET-6 and can comfortably read English technical documentation.
