When I’m not coding, I like aggressively cuddling others on the jiu-jitsu mat, reading, and educating myself.

Hangar Bay — robotics for every platform

Hangar Bay — Robotics Control Center for Mac

A native macOS app (Swift + SwiftUI) that gives budding roboticists one friendly place for robotics development: pick a validated Ubuntu + ROS 2 + Gazebo environment, pass a pre-flight prerequisite check, add hardware by photo, fly PX4 missions in simulation, and verify the evidence — while a managed Linux runtime does the heavy lifting underneath. No terminal, no version matrix, no install guides.

🍎 Native macOS · SwiftUI ✅ Preflight Checks 📷 Photo Hardware Intake 🐧 Managed Linux Runtime 🚁 PX4 + ROS 2
Engineering details
  • Live dashboard wired to real probes — UTM runtime state via utmctl, Tailscale link status, host summary — refreshed every few seconds
  • Preflight prerequisite checks (memory, disk, Xcode, UTM, VM state, Tailscale) with a one-click remedy on failures, plus a dependency-download manifest with sizes and sources
  • Environments are validated pairings — Ubuntu 24.04 + ROS 2 Jazzy + Gazebo Harmonic today, Ubuntu 22.04 + ROS 2 Humble next — so users never guess which versions belong together
  • Hardware intake by photo or scan: QR/serial decoding first, photo matching second, always confirm-before-configure (recognition engine in development)
  • Missions view built around a verified PX4 swarm-recovery demo — PASS, 8.095 m minimum separation vs 2.5 m required, 641 telemetry samples, 2 task reassignments
  • Managed-runtime prototype (Omega-Ubuntu VM) built and tuned end-to-end: 6-second boot, ROS 2 Jazzy + Gazebo Harmonic 8.15 verified headless
  • Stack: Swift · SwiftUI · macOS 14+ · UTM/QEMU · Ubuntu 24.04 · ROS 2 Jazzy · Gazebo Harmonic · PX4 · Micro XRCE-DDS · Tailscale
  • Status: v0.1 — first native build (Oct 2026); provisioning/download engine and golden-image packaging in progress.

Omega-1 Autonomous Robotics Platform

Omega-1 — Autonomous Robotics Platform

A fully operational autonomous robot running on Raspberry Pi 4B — drives, navigates, streams live video, and tracks its own position in real time. Controlled from a custom web dashboard with Xbox controller support, live sensor feeds, and a mission control map.

Built as a distributed system across three machines: the Pi handles real-time motor control and sensor fusion, a web UI runs on any laptop with no robot software installed, and an NVIDIA Jetson Orin handles GPU-accelerated object detection — all communicating over a VPN-secured network.

🤖 Autonomous Navigation 📷 Live Video Streaming 📍 Real-Time Localization 📡 Multi-Machine Network
Engineering details
  • Drives autonomously with obstacle avoidance — ultrasonic sensor triggers deceleration, pivot, and heading recovery without stopping abruptly
  • Estimates its own position using a Kalman filter that fuses dead-reckoning (motor commands) with visual landmark corrections (ArUco markers) — no GPS required
  • Streams live camera video to the browser with under 100 ms latency via a custom MJPEG proxy
  • Runs a full software simulation mode: the robot's physics and sensor geometry are modeled so the entire stack can be developed and tested without hardware
  • Detects objects with YOLOv8 on the Jetson Orin and relays results back to the Pi in real time over a compressed image stream (~500 KB/s vs 9 MB/s raw)
  • Solved a hardware bug where the motor driver corrupted servo signals at power-on — traced to a shared PWM clock; fixed with register verification and hard pulse clamping on every write
  • Eliminated ~240 unnecessary HTTP requests/minute from the frontend by introducing circuit breakers, shared polling contexts, and WebSocket health checks
  • Stack: Python · Go · TypeScript · React · Next.js · FastAPI · ROS2 · OpenCV · WebSockets · Docker · TailwindCSS
  • Status: Fully operational — live teleoperation, sensor streaming, localization, and multi-machine communication all running.

Includes an interactive 3D flight replay application built with Three.js.

🚁 Autonomous Navigation 🤖 Multi-UAV Coordination 🛡️ Fault Injection & Recovery 🧪 Verification & CI/CD 🌐 Interactive 3D Replay
Engineering details
  • ROS 2 mission state machines, A* path planning, LiDAR-based reactive obstacle avoidance, geofencing, failsafe handling, and resource-aware mission control
  • Cooperative two-UAV missions with task allocation, route reservations, separation monitoring, watchdogs, and automatic task reassignment after confirmed vehicle failure
  • Requirements-based verification: a 26-requirement catalog, independent telemetry analysis, fault injection, regression testing, and PASS/FAIL/SKIP reporting
  • 450 ROS-enabled Python tests, 27 browser tests, and 41 C++ checks, with GitHub Actions CI/CD and reproducible evidence reports
  • Stereo visual odometry, IMU fusion, velocity PID control, ArUco precision landing, and simulated GPS-aiding-loss handling
  • MAVLink v2 communication utilities, vehicle abstraction interfaces, and telemetry pipelines for simulated and hardware-facing integration
  • Two-UAV fault-recovery mission verified across 641 telemetry samples, two task reassignments, and 8.095 m minimum sampled horizontal separation against a 2.5 m requirement
  • Mission-completion defects found and corrected through independent verification, with the failing evidence kept as regression tests
  • Browser-based Three.js flight replay that visualizes recorded missions and fault recovery without a local PX4/Gazebo install
  • Stack: PX4 v1.15+ · ROS 2 Humble · Gazebo Harmonic · Python · C++ · MAVSDK · MAVLink · Micro XRCE-DDS · OpenCV · Three.js · GitHub Actions

RealmForge XR — Hands-On World Builder

A desktop and Meta Quest WebXR editor where you shape a miniature environment with your hands, place a robot, and watch it re-route when you move a wall. Originally built by a team of four in 12 hours for the MOLTEN Hackathon’s Worldbuild track, then expanded with real property-scan workflows.

⏱️ 12-Hour Hackathon ✋ Hand Interaction 🤖 A* Re-routing 🏠 Property Scans
  • Direct hand grab, two-hand scale and rotation, gestures, controller input, voice commands, and a wrist-mounted VR menu
  • Grid-based A* robot navigation over obstacle footprints, including automatic re-planning when the world changes
  • Imports up to 24 named GLB scan sections for rooms, garages, and outdoor areas, with alignment, floor labeling, visibility, and ceiling controls
  • Portable property bundles carry the world and its mesh files between devices; world scale ranges from tabletop 1:60 to life-size 1:1
  • Real-room awareness on Quest, voice commands, preset environments, save/load, and undo/redo
  • Stack: React 19 · TypeScript · Three.js · React Three Fiber · WebXR · Zustand · GLB/glTF · Vite · Vitest
  • Status: Live and automated tests pass; physical Quest interaction and real-world Scaniverse exports still need hands-on validation

Neon robot mascots coding with Claude and ChatGPT — Discord Agent Presence

Discord Agent Presence — Live AI Coding Status

Discord Rich Presence for AI coding tools. Like Discord's built-in "Playing Visual Studio Code" card, but for Claude, ChatGPT/Codex, Grok Build, Cursor and VS Code. Each card shows which projects you're working on, how many AI agents are running, and what they're doing right now.

🤖 5 AI Coding Apps ⚡ Live Agent Actions 🖼️ Mood-Based Images 🐍 Pure Python, 0 Deps
  • Reads Claude Code and Codex session transcripts to show what each agent is doing (editing, running tests, building, waiting for you) and counts agents across projects
  • Rotating status lines with git branch and diff stats, a commit streak, the model in use and GitHub CI status. Card images change with agent mood and the current action
  • Talks to Discord's local IPC socket directly, with one card per app. Uses /proc and X11 for app and window detection. One-line installer, a systemd user service and a doctor command
