Kuberik

A continuous delivery tool for Kubernetes built on top of Flux and the OpenKruise canary controller. It delivers full-featured, end-to-end deployment across multiple Kubernetes environments in a declarative way without pipeline engines, with each delivery stage implemented as a composable component (health checks, smoke tests, schedules, environment promotions, service dependencies). A recent release adds GitHub integration so users can track exactly what is deployed where and how far a change has progressed.

Keel

A productivity app that combines todo lists, pomodoro timers, and an AI executive coach to guide users through a full plan > execute > reflect cycle. The AI agent (text or voice) helps with planning and guides reflection but does not do the work for the user. An Android app is in beta and an iOS app is in development.

yups.io

A gateway service that redirects URLs to the correct proxy/frontend. It supports an official syntax like ?url=<target> as well as flexible URL formats for error handling.

Totem

A collaborative workspace app combining tasks, notes, and docs, built in Rust and available across desktop, web, and mobile (iOS first), with seamless real-time CRDT syncing and offline merge. It takes a local-first, ops-log approach for responsiveness and a ~100MB memory footprint, and is built on Markdown and SQLite as core formats so data stays portable and isn't locked into a proprietary platform. Currently seeking beta users and design partners ahead of launch.

Solace

Solace is a programming language that targets JavaScript without being a superset of it, unlike TypeScript. It aims to provide zero-runtime-cost safeguards such as optional values and error unions with Zig-like syntax, along with pattern matching and traits. Development is still in progress, with generics posing tricky challenges to the current approaches.

Team1-Factory

This open-source AI pipeline turns GitHub issues into merged pull requests by leveraging the user's Claude Code CLI subscription, acting as an automated AI software factory. It runs with full permissions, so it is intended to be run on a VPS or isolated environment rather than a personal machine.

Iosevka-inspired font generation system

A font generation system inspired by Iosevka but much simpler, involving technical work with the TTF and WOFF2 font formats.

ChonkyBlox

Block-based coding platform that uses AI on the back-end instead of complicated algorithms to derive code from block programs: each block carries an LLM instruction plus rules defined in a bespoke back-end harness. Kids can code using cardboard cut-out blocks and import programs by taking a photo; the system generates Arduino firmware, compiles, and flashes it to ESP32 from a single Docker web application. A working desktop application adds code assistance inside the Arduino IDE using the same web server API, and a simple PCB breadboard breakout with component connectors is still in development. It is a cheaper, open source alternative to current classroom coding systems, to be launched via Patreon.

Don

Don is a work companion app that helps users set goals, reminds them to take breaks, checks in on how they feel, judges them when they go off track, and celebrates their accomplishments.

treetags

This is a tree-sitter based Vi/Vim compatible tags generator. The main binary is being slimmed down by bundling only the tree-walking code for all supported languages and letting users download configured language grammars separately, possibly via WebAssembly-compiled grammars, while preserving the developer experience of adding support for newer languages.

52-Part Retention Lecture Series

A 52-part lecture series on user retention. Each week covers one aspect of retention through research and teaching, applied to two real-world products built by the author; five lectures have been published so far.

Tome & Tail

Tome & Tail is a Tamagotchi-style virtual pet for readers: a little black dragon living in a pixel-art library on an ESP32-S3 with a small round AMOLED screen. Starting a reading session makes the dragon read alongside the user, and what the user reads influences the dragon's appearance and habits (e.g., lots of sci-fi might give it starry wings). It won't die if the user goes a week without reading, is planned to stay playable offline, and can optionally sync to Booklary, a reading tracker. Development is planned in C++ as the author's first ESP32 project, with commissioned pixel art based on AI-generated concept images.

Solanda

A zero-dependency UI library built on native web components, designed to help with UI development without bloating a project. It works with Vue/Nuxt (tested) as well as React, Angular, and Svelte, and was just made public after a year of use in the author's personal projects. Licensed under AGPLv3, with open consideration of switching to MIT due to adoption concerns.

Online guidance solver for KSA

This online guidance solver lets you control a Kitten Space Agency (KSA) rocket from the command line for a variety of maneuvers such as launch and rendezvous. It uses successive convexification to turn the full nonlinear trajectory problem into a sequence of convex problems with linear constraints and quadratic objective. Planned follow-on experiments include full mission planning, Falcon-9-style ascent with split control, and vehicle swarms.

TUI roguelike-style word game

A word game built with a TUI graphical style that looks like a roguelike but has more going on beneath the surface, with an emphasis on carefully developed game systems and meta rather than rapid development.

Automated fun-factor playtesting with agents

An automated playtesting approach that uses agents to test a game's "fun factor" and generate bugs and feedback reports that sound like real player feedback; the method may be codified since nobody else appears to be attempting it with agents.

Makefaster

This tool speeds up frontend performance by running autoresearch loops that apply distilled learnings from analyzing top GitHub repositories to the user's own repo. It works with existing Claude, Cursor, or Codex subscriptions through a custom TUI, and includes a leaderboard of the most common performance wins.

Tella Stories

Tella Stories is a personalized storytelling app for kids that generates stories from the child's actual life — their family, friends, pets, and the things they're nervous about that week — so the story is about their world and imagination and grows with them. It leverages multiple AI services to create the stories, gives kids agency through choices instead of passively watching, avoids an educational/instructional approach, and aims for Bluey-level quality as a trustworthy, enjoyable screen-time alternative.

Broomsday

This service sends Denver residents email and SMS notifications the night before street sweeping parking restrictions take effect on their block(s), helping them move their cars and avoid tickets. Email notifications are free and SMS alerts come with a paid season pass; it is finished and in friends-and-family testing before marketing.

HailPass

This service integrates open weather data sources (mostly NWS/NOAA plus impact reporters, with a small hail-specific ML model in development) to give Front Range residents a 5-10 minute heads-up before damaging hail arrives at their location. Prediction accuracy is still being tuned, with a target release of April 2027.

Job board doomscrolling bot

A bot that automatically browses job boards to surface potential job matches. It recycles parsing logic across target sites, favoring schema.org JSON-LD parsing over DOM-based scraping, and is built as a local-first app intended to run across multiple clients, with a browser extension to collect potential matches passively. It is being reworked around vanilla Web Components, view transitions, and Signals to reduce framework dependence.
