A full-blown ERP being implemented for a complicated regulated trade, replacing a 15-year-old SaaS that has not had a major overhaul in a while; the author sees big room for improvement and simplification in the process.
A tool for creating recipe cards, built as a hobby project over 7 months with the goal of becoming the best recipe card creator available.
An interactive learning platform that turns real outage case studies into 5-minute system design scenarios: the player steps through fixing an outage as if they were the one on-call, then sees what the real team did and roughly how their own choices would have played out. Choices are scored against what was known at that minute rather than judged in hindsight, since many correct choices exist and companies sometimes got it wrong. The first published case covers Supabase's February outage, where a monitoring deploy cut off a whole AWS region.
A survival guide for creative people that answers questions the author had but found no answers for, covering why receiving feedback hurts, how to filter conversations that assess versus antagonize, and how creativity can be a process of self-care and how to maximize its benefit. The guide is a work in progress with more topics to be added.
A free web platform for comparing medicine prices across top Indian pharmacies to help users reduce their monthly medication costs, currently serving about 1K monthly users and adding features based on user feedback.
Platform offering daily domain lists, DNS zone files, and historical domain data, aiming to be the most useful platform for domain and web data. Recently achieved full coverage for five ccTLD zones (.se, .nu, .li, .ee, .ch) with more ccTLDs in progress, and includes continent filtering for ccTLDs, a coverage filter, country flags, and growth charts for every zone.
Esara is a math-based AI hiring platform for candidate sourcing and explainable evaluation of candidates. It was recently incorporated in Berlin.
A game bot built with a reinforcement learning approach for a turn-based game with a lot of hidden information. Inspired by the pluto bot that won a major bot tournament, it aims to see how far such a bot can get on a much smaller budget than the tens of thousands of dollars reportedly spent on similar bots.
Buildopsy is a learning platform offering free, unique courses, currently featuring a learning path for system design enthusiasts that removes the boring parts of traditional coursework.
Chaffiti is a conversation layer for the internet that lets any webpage have its own comment section, aiming to reduce the need to reference multiple services for context on things like potential employers, service providers, property managers, and real estate listings. It is currently in iOS and macOS alpha testing.
An open-source Chrome extension that highlights and shades data tables on the web. Because a simple rule like 'big numbers = green, small numbers = red' breaks down when the data is inverted or ambiguous, it uses Jev and other small decision models to judge the cardinality and ordinality of each column's data before applying color shading.
blastQR is a FOSS, cross-platform app and CLI tool for truly offline file transfers using animated QR code sequences, currently reaching peak transfer speeds of 1.4MB/s. It supports use cases such as large-screen broadcasts so people can receive information during internet blackouts, quick private offline sharing of pictures and small files, air-gapped systems, and airplanes.
drawdb is a web application under active development, available at drawdb.app.
A command-line interface designed for humans and agents, currently in development alongside the author's work on drawdb.
An original game being created for GitHub Game Off 2026; the theme resonated with the author, the direction is coming together well, and the development process has been enjoyable.
This tool checks AI answers against PDFs: ask a question, then click to verify, and the answer opens on the source passage highlighted in the original document.
A website presenting a world map of birds, built for the author's son to explore birds around the world.
A formally verified web browser written in Rust, built as an experiment in using AI during development. It currently works as a Lynx-style text browser with sandboxed rendering, HTML parsing, and link navigation, with the goal of pushing the formal verification approach further.
A desktop GitHub client focused on improving the user experience for managing pull requests and reviewing code. It includes Slack integrations and support for connecting AI models (such as Claude and Codex) via API keys or the user's own subscriptions.
Free and open-source web app that helps users complete USCIS immigration forms and the DS-160 without wrestling with complicated government PDFs. All forms are available for free, with a paid version offering additional features.
A lightweight F-Droid-style Android app that uses ADB to download apps directly to the phone, avoiding the lengthy procedures normally needed to install third-party apps. The app is nearly complete and planned for GitHub release; an in-app security layer for downloads is still in development (about two months of work) because the approach bypasses Android's own security.
An advanced Dutch income tax calculator web app that shows all intermediate calculation steps, dependencies, and references to laws and yearly parameters. It supports comparing scenarios and optimizing how deductions are divided between partners using mixed integer linear programming (MILP). Tax rules are written as regular code converted into a calculation graph via Lisp macros, which drives tax computation, step display, dependency visualization, and batch/reactive functions. Scenarios can be loaded from PDF tax returns to avoid manual data entry, and the app runs entirely locally in the browser with no backend data sharing.
This is a Peruvian specialty coffee and cacao shop in Munich, run together with the author's wife, inviting people to visit and chat.
Open-source tool that lets users view the code changes made by an AI agent step-by-step, making it easier to understand them.
A digitized archive of a family genealogy book compiled in the 1990s that traces the family back to the 1600s. Roughly 280 scanned pages were transcribed using Claude, which spawned subagents to transcribe the text and flag illegible passages for rescan. The project has produced a digital PDF of the book, an mdbook site, a GEDCOM export, and an interactive website for browsing the family tree, with plans to extend the records using information from relatives on both sides of the family.
This project builds a correctness layer between man and machine using formal methods, specifically category-theory ologs that model the structure (taxonomy and ontology) of a business domain. It includes a manifesto laying out the vision and an olog editor for authoring these domain models.
This project implements the author's own loop method, which has already been tested, by wrapping it with a finite state machine (FSM / Stately / XState) to produce a likely-correct loop; a study page documents the speed-of-thought approach.
Aisma is a video editor that edits videos by parts: it understands simple natural-language requests in any language and can edit just a portion of a video instead of the whole thing, so users don't pay for the full length when only changing something in the middle. It gives attention to videos with many short shots, lets users continue editing short parts separately when a generation isn't complete, and returns credits for segments that don't contain the target subject. It improves through a feedback loop where videos it misunderstands are used to teach it how to handle such videos correctly. Available on web, iOS, and Android.
An ebook reading app built to deliver the best possible reading experience, released on Android with an iOS release coming soon. It grew out of a years-long list of desired reading app features.
Team chat platform where AI agents work alongside human team members.
