Inside a coding agent run
I built trce, a local trace recorder that turns Claude Code and Codex sessions into structured traces you can inspect, share, and analyze.
Hey, I'm Tair Asim.
I'm a product engineer and founder with a background in developer tools. Right now, I'm building something new around devtools and AI.
Most recently, I led product at sync. labs (yc w24/gv), building AI tools for lipsync, video dubbing + editing.
Prior to that, I was a founding engineer at buildspace (yc s20/a16z), a senior engineer at thirdweb, consulted for Fortune 500 companies, taught at universities and bootcamps, and co-founded two devtools startups.
