We're big believers in multi-year infrastructure bets. After a few years of Ruby infra work, our in-house Ruby compiler is now 22–170% faster than Ruby's default implementation for Stripe's production API traffic. If interested in working on such problems, we're hiring!

I've tried hard to see this from Apple's point of view. But inescapably, this is government spyware installed by Apple based on a presumption of guilt. Though Apple wrote the code, its function is to scan personal data and report it to government. eff.org/deeplinks/2021…

I've measured "engineering velocity" for a very long time, but I'm starting to focus more on "engineering drag". These are the things that slow down engineering teams. This includes product discovery, local dev environments, CI/CD pipelines, etc. Reduce drag to go faster.

ICE typically isn't the federal agency in charge of detaining migrant children. However, a policy loophole has allowed ICE to detain immigrant children at one youth detention facility for decades with no explanation. New from Esmy Jimenez: bit.ly/3nfwLvt

Over the weekend, my team at Stripe converted the company's largest JS codebase from Flow to TypeScript. We modified about 3.5 million lines of code, and then hundreds of developers came in Monday morning ready to write TS.

Over five years, Sorbet (Sorbet) has improved developer productivity while making our code @Stripe more delightful and understandable. We can’t wait to see what the next five years have in store. stripe.com/blog/sorbet-st…

People tend to think of engineering at Stripe being about slick product launches, but we also have some awesome internal infra. I'm excited that we're publicly talking about our Bazel + Remote Build system the build team and I have been working on over the last few years.

This thread is a great read, but I'd also like to just generally show some public appreciation for Rebecca Murphey and how she's made us think more holistically about the internal developer experience at Stripe.

Stripe has upstreamed our internal changes to Rubyfmt: github.com/penelopezone/r…. I haven't cut a release yet but please clone and check out the branch down and try it out. This is the first daily drivable build of Rubyfmt.

Friends: the only thing that made me better at interviewing for jobs was interviewing for jobs. To that end, I've blocked off 5pm—6pm EST M-F for the rest of the year for mock interviews. Happy to give either a technical or non-technical interview: savvycal.com/buttondown/moc…

Stripe is a company of developers, and a company building for developers. So we spend a lot of time thinking about how to make sure developers have productive days. Excited to welcome Okay to the team to build more effectiveness tools for Stripe engineers.

I had the pleasure of talking to the fantastic Rebecca Murphey for Swarmia's Engineering Unblocked podcast about the last 5 years of growth for myself and the Developer Productivity team at Stripe Check it out at unblocked.fm/episodes/ainsl…

For folks interested in how Stripe does engineering, this deep dive in The Pragmatic Engineer lifts the curtain. Really enjoyed speaking with Gergely Orosz!

your level at tech companies is actually how many frames you read off the trace before asking for help
