Icebreaker Question App

Modern web app for instant, high-quality icebreaker questions with multilingual support. Built as a project that does not need updates using only Astro, Tailwind & Web Components, kept raw and simple for the joy of working directly with TypeScript, and to minimize ongoing maintenance. Generated 17,000+ questions with AI workflows, refined them using text embeddings and AI filtering, then handpicked and improved the final ~860. Hosted on static-host.eu with privacy-first analytics.

Telegram AI Agent

Built a personal AI agent on Telegram that cut my daily YouTube consumption from 4-5 hours down to under half an hour. The agent transcribes WhatsApp audio messages I forward to it, transcribes and summarizes YouTube videos on demand, and proactively scans all my YouTube subscriptions each morning, surfacing new releases and letting me approve which ones to receive as clean, summarized transcriptions.
