Hello!

I'm a software developer who's got an eye for performant and intuitive systems. I've worked at companies in the defense, finance, ecommerce, SaaS and security space. Most recently, I worked on building https://merrilin.ai, and I've written about this here: https://tech.stonecharioteer.com/posts/2026/merrilin/

I've also hit the HN frontpage 4 times last year, writing articles about learning Ruby and its internals.

I'm the guy you hire when you want performant code, something that's scalable in this world of vibe-coded stuff. I'm also excellent at writing deeply technical blog articles and have given talks at PyCon India, RootConf and the Bengaluru Python meetup group BangPypers. I'm also notorious for reading the PostgreSQL documentation on livestream.

We built https://merrilin.ai, primarily because we weren't happy with the book reading apps out there. Sign up for the waitlist!

I want to be as good as you at performance engineering. It's the direction I want for my career.

Something tells me that in a year we'll see a post about why you left OpenAI.

Sama won't listen to anyone. That's why. None of these CEOs are going to listen.

I prefer https://old.reddit.com/r/subredditsimulator in its heyday.

There is.

https://realpython.com/products/cpython-internals-book/ But it's for 3.9 and doesn't cover the massive changes regarding delayed annotations and the GIL updates

The Ruby under a Microscope guy is updating it.

That's nice too, but it seems to be more a tour of the code base, and doesn't have the detailled diagrams of memory layout that the Ruby book and the one posted here have.

On Android https://donotnotify.com/

This is fucking excellent. Especially since the companies do not honor their notification type.

Oh boy. I wanted to get a license for this. I waited for the price to drop, and now I'm glad I never did it.

Spend the evening setting up a local DNS namespace on my homelab.

That my colleagues like me despite me being a bad fit for the role here at my company. I feel good, I really like them here at Chatwoot but I'm not who they need right now. It's my last week here, and it's only been 3.5 months but they feel like family. It's sad that I had to quit but I'll miss these good people.

I hit the HN Front page thrice for my posts on Ruby last year. Going to write way more soon. I write about Python, Rust, Linux and some tooling. I'll also write about concurrency next.
