- On 2026-10-16 he reposted Cognition's Devin Oncall launch, writing verbatim: "Your favorite software engineer just got even better at going oncall! From the world-class team that brought you TierZero, Devin Oncall is a step change in autonomous alert investigation and incident resolution. Check it out!" Devin Oncall is the product line most directly descended from TierZero.Oct 16, 2026

- His TierZero announcement opened, verbatim: "Five years ago I was an engineer getting paged at 2am. Today I'm joining TierZero AI as their first AE." His pitch builds directly on his own on-call history as an engineer.Apr 23, 2026Five years ago I was an engineer getting paged at 2am. Today I'm joining TierZero AI as their first AE. AI-generated code is accelerating teams. The problem is, it's also making production more brittle. The same teams shipping faster than ever are building systems faster than they can understand. Fighting that with more humans on-call doesn't scale. The answer is AI that watches, learns, responds, and helps teams get ahead of the failure modes their own velocity is creating. That's what TierZero is building. Thank you to Anhang Z. and Yun Park for the opportunity to build this from the gro
- At Grafana Labs (Jan 2025-Apr 2026) he was a Sales Development Representative and was named AMER SDR of the Year FY26 at 144% attainment; he called the move 'went to the dark side to help engineers illuminate what's going wrong in prod.'Jan 2025
- On 2026-09-29 he shared a Cognition customer story on Loop, writing verbatim: "I work with a bunch of forward-thinking teams, but Loop definitely raises the bar on what it means to build a company AI-native from the ground-up. Definitely give it a read".Sep 29, 2026

GTM Hire #1 AI production agents for engineering teams that are tired of paging humans for problems machines can solve.
Went to the dark side to help engineers illuminate what’s going wrong in prod. AMER SDR of the Year FY26 - 144% attainment
Worked on open source kubernetes. Helped make the kubernetes API server more expressive and extensible.
Built version one of “Pachyderm Hub” our fully managed, cloud-hosted version of pachyderm.
