Experience

Reddit Sudoku Solver

https://github.com/lisudoku/reddit_sudoku_solver
A Reddit bot that regularly reads puzzle submissions on r/sudoku parses the image using OpenCV, detects digits using Tesseract, solves the Sudoku grid, and leaves a comment with hints on how to proceed to solve the puzzle.

Example submission https://www.reddit.com/r/sudoku/comments/11kqolg/is_there_an_actual_way_for_me_for_me_to_work_this

Lisudoku

https://lisudoku.xyz
A sudoku website where you can solve puzzles. Its main features are:
1. 11 supported Sudoku variants
2. Multiple grid sizes (4x4, 6x6, 9x9)
3. Watch other solvers play live
4. Gives hints when a player is stuck
5. Build puzzles and run the solver on any puzzle
6. Share the puzzle you built, and others can solve it
7. Solve or run the solver on puzzles imported from f-puzzles
8. No account is required to use the website

I created it because I recently started liking Sudoku, and I thought existing Sudoku websites are outdated.

Facebook Messenger Reminder Bot

https://github.com/PlayLikeNeverB4/bucevschi-bot
Created a Facebook Messenger bot that sends reminders before programming competitions. Users need to send a message to the bot to activate notifications and start receiving reminders 24 hours before each competition. The competition data was obtained through a public API.
