Hi! I research, design, and develop computational interfaces.

I'm a principal design engineer at Replit ↗, where I work on Future Of Coding efforts for a software development platform.

Previously, I was a principal investigator at Ink&Switch ↗, where I explored Programmable Ink and back-of-the-envelope-computation.

Before that, I led flow/control ↗, a boutique R&D consultancy, where we specialized in solving complex design × computation problems.

Check out the bio page for more details.

In my free time, I tinker on personal projects, research independently, and make ambient music from deconstructed acoustic sounds.

Projects

I've documented 55 of my ~213 projects.
A couple of highlights below:

Replit Agent — IDE for Humans and LLMs
DIY Pen Plotter — Designed & Built from Scratch
Crosscut — Drawing Dynamic Models
Cartographist — Web Browser Optimized for Rabbit-Holing
FabFungus — Art Installation Inspired by Questions of Digital Life and Cellular Growth
Archivist — Tools For Archiving and Exploring

Stats

I've been tracking how I spend my time for the last 11 years, using self-made tools which evolve with what I do. The system contains 40814 entries, and the charts below were updated on 2025-06-08.

Below you can see how I divided my time between  work and  personal projects every week, for the last two years. The exact values don't matter, I'm just trying to be consistent with projects, and take regular breaks from work:

I also pay attention to two habits:  reading/writing and  exercising.
Here you can see how well I'm doing, on a daily scale:
