Who's on call? How we improved schedule rendering performance 2,500x
A look at how on-call schedules work, and how we made rendering them 2,500× faster — through profiling, smarter algorithms, and some Claude.
DevEx matters for coding agents, too
When AI can scaffold out entire features in seconds and you have multiple agents all working in parallel on different tasks, a ninety-second feedback loop kills your flow state completely. We've recently invested in dramatically speeding up our developer feedback cycles, cutting some by 95% to address this. In this post we’ll share what that journey looked like, why we did it and what it taught us about building for the AI era.
How we're shipping faster with Claude Code and Git Worktrees
Learn how we accelerated development with Claude Code and Git Worktrees - a powerful combination that enables parallel AI-assisted coding, streamlined workflows, and faster feature delivery.
Building On-call: Building a multi-platform on-call mobile app
What does it take to build a greenfield mobile app in 2024? When we launched On-call earlier this year, we had to find out.
We used GPT-4 during a hackathon—here's what we learned
We learned a lot about using OpenAI and which things to keep an eye on to decide when it’s worth revisiting.
Battling database performance
Earlier this year, we experienced intermittent timeouts in our application — here’s how we tried to address the underlying issue over the next two weeks.
