Hire the Best Algorithm Developers
in China

I am a senior C++ and AI developer with over 9 years of experience in AI-related development. I have worked at companies such as Alibaba Group and Intel OCT. My projects mainly focus on computer vision , audio and LLM applications, and my programming languages are C++, Rust, cuda and Python. I am currently a freelancer, part-time developing an artificial intelligence agent application framework for a startup company. My most recent work is the open-source project vt-transformer on GitHub, which is a Transformer framework based on C++ for edge computing. I am very willing to finding some AI project development work on upwrok.

I build clean, efficient, edge-case-proof technical solutions with C++ and full-stack web tools, drawing on USACO Gold-level algorithmic thinking to deliver correctness, speed, and maintainability. From fixing slow, underperforming code to building functional web features with formal API specifications, I focus on tangible, production-ready results. Services I provide: • Algorithm & data structure implementation: Graph traversal, dynamic programming, binary search, sorting, segment trees, and other competitive programming constructs in C++, Python, or Java; tuned for strict time & memory constraints. • Latency fixing & performance optimization: Profile slow code, reduce time/space complexity, optimize memory access patterns, cut API response delays, and refactor brute-force solutions into linear/logarithmic efficiency. • Web & backend development: Build and extend web applications with HTML/CSS/JavaScript + React frontend; design RESTful APIs with fully defined input parameters, validation rules, structured JSON output schemas, and standardized error handling. • Debugging & code quality: Diagnose hard-to-reproduce bugs, patch edge-case failures, write targeted test cases, and document function interfaces with clear input/output specifications. • Custom tools & data processing: Build lightweight scripts, batch parsers, and utility tools for automation and batch data handling tasks. My USACO background trained me to work systematically under tight constraints: define requirements, isolate bottlenecks, select the optimal approach, implement cleanly, validate edge cases, and explain results clearly. I specialize in small-to-medium technical tasks where strong problem-solving makes a clear difference — from algorithm challenges and backend logic to performance-sensitive code and web feature builds.

I am experienced in Linux/Windows C/C++ development, both embedded and desktop software/driver, qt qml for application UI, python for automation and machine learning. Also has other development experiences as C#/Java/Pick Basic.
