Work Board is a personal board built on GitHub issues. It runs with no server: you paste a fine-grained token and the page talks to GitHub straight from the browser.

Mancala is a two-game board game for the browser: Kalah, the version most people know, and Ba-awa, the game played in Ghana, where one move crosses the board many times and the winner takes pits off the loser between rounds.

WhatsApp Without Saving a Contact is a one-screen web tool that opens a WhatsApp chat with any number. Pick the country, type the number, open the chat.

Liga UNDER is a live tournament website for a taekwondo competition. Spectators and athletes follow the running order of combats by tatami, the standings of each round-robin group, and every athlete's profile — updating in near real time during the event.

Taboo is a party game web app for playing the classic word-guessing game across several phones in the same room — no server, no rooms, no realtime sync. Every device reconstructs the full game state from a shared seed and turn number agreed verbally.

Random Option Picker is a web tool that picks one or more options at random from a list, with shareable URLs and an optional seed so the same link always reproduces the same draw. Useful for picking a daily standup moderator, dice rolls, choosing activities, or any small decision worth keeping reproducible.

ChatGPT Pong is a classic Pong game generated entirely by ChatGPT (GPT-3.5) in December 2022, right after the initial release of ChatGPT. It was my first ever software project created by an AI — and it blew my mind.
