sealed.vote

A browser-based application relying on homomorphic encryption allowing for ranked-choice voting with ranking choices from 1 to 10 in a way such that nobody, including the server, can know what the individual choices were! Only the result is publicly known. Uses the threshold-elgamal package: https://www.npmjs.com/package/threshold-elgamal.

bob

Hexapod breadboard-on-legs toy project based on ESP32-S3 with a voice, camera vision, autonomous basic movement and seeing. Uses OpenAI Realtime API and Structured Output API to process visual data and talk to the user in (delayed, due to processing power constraints) real time with a realistic voice.

piech.dev

My personal page. It turned into a complex project itself: it supports loading all projects' information directly from GitHub, renders markdown, the whole site is pre-rendered and served with zero JS. It includes dynamic <meta> tags for each project, including og:image tags with sizes. Perfect 100/100/100/100 Lighthouse score for all routes.

aliases.sh preview

aliases.sh

My curated list of bash aliases that I use, hosted online so that I can access it easily from anywhere, especially on new devices. It's aimed mostly at developers using git and NPM, but it has other useful aliases as well. Includes an alias concatenating the whole directory into a text file for LLM workflows.

tiles.town

Puzzle game with a global scoreboard requiring you to flip all tiles to the same side. Built ages ago in jQuery as a toy project to learn JavaScript better, then rewritten in 2016-ish to learn React + Redux, more recently rewritten to TypeScript.
