Honorfit Blocker
A mobile app that blocks your phone screen until you complete exercises such as pushups or situps. It works on the honor system instead of tracking you with a camera, aiming to turn screen addiction into getting fit. An iPhone version is coming soon.
Konvoi.ai
A fleet management solution that integrates with all major transportation IoT systems in Europe.
ESP32 CAN bus display
A DIY hardware project that decodes CAN bus data and displays real-time CAN bus readings on a 4-inch screen driven by an ESP32.
Gaming Couch
A web-based local multiplayer party game platform offering 20+ competitive, action-based mini-games playable free in early access. Games run in the browser with no downloads or installs; players use phones as controllers (gamepads also work), each game supports up to 8 players, and quick ~1-minute rounds keep the pace. It avoids language-based trivia and turn-based games so groups with mixed language fluency can play together. The platform also provides third-party development tools (in private beta) that let game developers publish their own party minigames, and the first third-party game has already launched.
Go circuit simulator
A circuit simulator written from scratch in Go as a fun personal project, built alongside relearning electrical engineering topics. The author does all the coding and architecture decisions personally, using an AI assistant only as an ADHD focus aid to stay on track, log ideas and experiments, and provide cited references to documentation, specs, and research.
Math Can Be A Hobby
A YouTube lecture series working through Serge Lang's Basic Mathematics, produced as deliberate teaching practice while the creator retrains to become a schoolteacher; the first video has earned 350k+ views and is still growing.
jcpractices math
A YouTube livestream channel sharing the creator's near-daily math study sessions, thinking out loud with an iPad on screen, with an emphasis on algebra and number theory.
ffl
An agent-first file transfer/delivery platform that serves as the data plane of the delivery system, paired with an MCP companion (ffl-mcp) and a control-plane service.
ffl-mcp
MCP companion to the ffl file transfer/delivery platform, developed alongside it as part of the agent-first delivery system.
Mailtrigger
A control-plane service that pairs with the ffl data plane to run the agent-first file delivery system, which is reported to be running well.
Grokbot
A team of AI employees shaped by the company's long-term org chart and culture, supported by purpose-built MCP tooling (such as MIS, mail, kanban, and ERP) so AI employees can work fully autonomously and operate independently; planned to be open sourced once things run smoothly.
AI-powered Craigslist apartment search
This personal AI tool scoured Craigslist listings for the author's recent apartment search, evaluating must-have criteria in listing text and examining images of promising listings. It favored casting a wide net and fine-tuning requirements as results came in, with the goal of quality over speed.
squid-lang
A programming language generated by an LLM and designed for LLMs to use, presented as the opposite of a human-readable agent-oriented language.
Opaque
A security product for creating gated policy control and auditing of LLMs.
Curbwise
A community crowdsourcing product geared at improving your community.
Ukodus
A sudoku engine available as a terminal UI (TUI), WebAssembly, and iOS app.
Adanima
An autonomous marking product.
Real-Time Communication System
A real-time communication system whose frontend client implements WhatsApp-style messaging features, including chat rosters, read receipts, audio/video calls, and voice messages. The project is currently focused on the client-side UI/UX.
grpc-comparator
A proxy that sits between an original service and its replacement, calculating timing and any deltas in responses for the response attributes the user configures it to care about.
edge-flipt
A tool that uses Istio's ext_authz to inject headers derived from Flipt snapshot evaluations for downstream consumption, including VirtualService route selection.
WYSIWYG Markdown Editor
A WYSIWYG Markdown editor for Mac, iPhone, and iPad that is mostly Obsidian compatible. Launched less than two months ago with 2K downloads, and under active development to improve it.
mouse
A coding agent that can be used via text messaging, ranked #1 on the Frontier Harness benchmark.
g023code
A coding harness for DeepSeek V4.x that lets the LLM set its own reasoning for each response, enables bi-directional communication between subagents, and includes a todo sub-orchestrator that passes issues surfaced by one subagent to the next so they are fixed before the next task begins. It also caps reasoning at 75% to curb overthinking and includes cost-effective processing and cost efficiency management.
ghostlock-oneplus fork
A fork of the ghostlock-oneplus repository being worked on to root Android tablets that have not yet been unlocked ('liberated').
Bitcoin derivatives arbitrage model
A model for arbitrage trading of Bitcoin derivatives, built on the econometric studies of Thorp and Kassouf (pre-Black-Scholes), using a low-frequency strategy.
Simulated Multiplayer Clown vs. Demon FPS
An old-school first-person shooter where clowns and demons fight it out, playable solo or with invited friends in co-op. The multiplayer feel is simulated with virtual players so the server is always full, including simulated clans, chat, and trash talking. Planned to launch on Steam, hopefully early 2027.
StressingLLMs
This project explores reverse engineering using LLMs together with Ghidra, with a particular focus on how code complexity affects the LLM-assisted analysis process. Results of experiments run with opencode are published as a write-up on GitHub Pages.
ken
A dependently typed programming language based on Observational Type Theory, designed for AI agents to write and humans to read — 'Lean4 for software engineering'. It uses constructivist logic where propositions can be true, false, or unknown; ships a compiler targeting the Linux ABI (in progress) with an interpreter that acts as an oracle for tests; has a built-in row polymorphic effect model; and provides fine-grained capability and resource-based security. The goal is a comprehensive first-party software catalog.
bboy.app personal blog
A personal blog at bboy.app that the author recently optimized.
