AI is reshaping software engineering into two increasingly distinct paths: product engineers focused on what to build and why, and foundational engineers focused on the deep systems, infrastructure, security, and scale that make it possible. As AI handles more of the "how," engineers will have to decide where they want to create the most impact.

@bitares @calcom Indeed. The number of downstream effects of meetings not scheduling correctly is substantial.

99.92% uptime this year. Highest we've ever had at @calcom , by far. We could ship faster and let users eat the bugs. Some big names in our space do exactly that. But that's just not how we roll anymore. If people are relying on us to run their scheduling, it has to actually work. In fact, I want this number to be 99.99% soon.

@kurtkalwin @calcom We had a couple lapses in internal processes for reviewing heavy DB hits and firewall changes. Those have since been rectified.

Happy to see this. We are in a time of transition and the code does still matter.

There will come a time when how code is written won't matter. But for now, I still care that the code looks and reads right. I'm not ready to let go :)

I still spend a LOT of time figuring out the right abstractions and interfaces (user and programming). I recently built two components for shadcn/react. Each took weeks of UX research, experimentation, and iteration to get right. AI hasn't accelerated this part yet, at least

I've always hated "move fast and break things." It's an excuse for not doing the work right. So why are we constantly okay with breaking things? And with AI there's no excuse left.

To secure open-source software, we’re launching OSS Scanner. We’ll use our frontier models to periodically scan opted-in open-source projects for vulnerabilities, at no cost. Our reports will provide a proof-of-concept, explanation, and suggested fix. anthropic.com/research/launc…

I'm a private person. Barely touched social media for years. Then my brother, a robotics professor, convinced me to start posting. After 20 years in this, if I can share something that actually helps another engineer, why wouldn't I? That's the whole point. I just want to teach.

AI can accelerate engineering, but you can't build trust by assuming everyone understands everything it generates. Strong test suites, CI checks, AI and human reviews, and experienced engineers create the guardrails that keep AI-assisted development moving in the right direction, especially for junior teammates still building judgment.

Great leaders don't control every task. They create the space for people to think, challenge, and solve problems creatively. Leadership is about serving your team, being a sounding board, and helping people find the best solutions rather than using the role to control them.

Frantically fixing a confusing product caused by frantic shipping is just more of the same. Pause and step back. Get the team clear on what you’re building and why. Have clarity to guide the shape, what ships and what doesn’t. Quality is a way of working, not a cleanup sprint.

"Bring me solutions, not problems" is the fastest way to kill trust with your engineers. It teaches them to hide problems or show up with half-baked fixes they're scared to be judged on. So bring me the problem. We'll figure out the solution together. That's the job.

I bet engineering teams who built their systems using DDD are quietly smiling these days as exposing domain capabilities to APIs/MCPs/agents would be a breeze.

We’ve been working hard to building guardrails such that AI produces the code we actually want, the same way each time. Product teams spec an idea and ship it. Then best practices make sure what comes out is on-pattern. Because consistency is what lets you move fast with confidence.
