Automating LeetCode Documentation with a Local LLM + GitHub Workflow

This is a submission for the DEV Weekend Challenge: Community The Community This project is built for developers who actively solve LeetCode problems and share their learning publicly. Many developers aim to stay consistent, build in public, and grow within the coding community — but the documentation process often becomes repetitive and time-consuming. I built this tool to reduce friction in that workflow and help developers focus more on problem-solving rather than manual documentation tasks. What I Built I built LeetCode AutoSync , a CLI automation tool that: Adds LeetCode solutions locally with structured metadata Automatically updates and sorts the README by difficulty Generates high-quality structured solution write-ups using a locally hosted LLM (via Ollama) Logs token usage and performance metrics into an Excel sheet Supports multiple programming languages (Python, SQL, C++, Java) Uses a background worker queue to generate AI content asynchronously Gracefully shuts down and man
