Hi! I research, design, and develop computational interfaces.
I'm a principal design engineer at Replit ↗, where I work on Future Of Coding initiatives for an agentic development environment.
Previously, I was a principal investigator at Ink&Switch ↗, where I explored Programmable Ink and End-User Programming.
Before that, I led flow/control ↗ — a boutique R&D consultancy, where we specialized in building complex design × computation interfaces.
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.
I've documented 56 of my ~214 projects.
A couple of highlights below:
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 41096 entries, and the charts below were updated on 2025-07-13.
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:
