Hi, I’m Donovan; a senior full-stack engineer designing and building for and with agentic systems.
WORK
Here are a few things I've enjoyed building. You can find more of my work on GitHub.
dicesuki
A tactile 3D dice roller with physics simulation, device-motion controls, and enough polish to make random numbers feel dramatic.
#dice#3d#typescript
lexitiles
A mobile-first word-building puzzle with a tiny surface area and a very annoying amount of product taste packed into it.
#word game#mobile#typescript
typeline
A full typing game for tuning feel, rhythm, and input feedback without dragging a bloated product surface behind it.
#typing#svelte#typescript
sample-sound
A tiny browser soundboard for fast meme/audio triggers, keyboard shortcuts, and exactly the amount of chaos the room deserves.
#soundboard#audio#javascript
Open Music Player
A local-first music player experiment aimed at waveform-heavy, DJ-ish listening instead of yet another dead-flat playlist table.
#music#mobile#dart
Relay IDE
A remote web interface for steering real coding-agent sessions from anywhere without pretending the terminal stopped existing.
#agents#developer tooling#typescript
Dynamic Workflows
A Hermes plugin prototype for letting agents turn plans into executable, inspectable workflows instead of vibes in a transcript.
#agents#hermes#python
Carabiner Memory
A Hermes plugin for Honcho-backed collaboration memory: handoffs, peer feedback, and agent relationship episodes that actually persist.
#hermes#memory#python
ComfyUI Backend
A ComfyUI image-generation backend for Hermes, bridging local node graphs into the image_generate tool path.
#hermes#image gen#python
Remote Hosts
A Hermes plugin for explicit SSH-backed remote host tools.
#hermes#ssh#python
Talent Roster
A Hermes plugin for teammate roster routing and Kanban-backed profile assignment across specialist agents.
#hermes#kanban#python
Belayer
A multi-repo autonomous coding-agent orchestrator built around supervision, recovery, and making agents leave useful evidence behind.
