Of course, it's @zacsweers.dev with the main talk I wanted to catch 🙃

I am really enjoying using Warp as my daily Terminal
I never thought AI and the terminal would mix, but it's definitely helped improve so much of my workflow 🚀
Highly recommend giving it a try if you haven't already!

I've been losing my mind for the last few evenings trying to figure out how to write a KMP compatible Gzip decompression method
JVM & Android were easy but iOS was driving me crazy with zlib C interop and alloc calls!
TIL it turns out Okio can do it all, in two lines of code 😂

It's time to talk about some new practices that you may want to follow
It will be available at the same link this Sunday 👩🏻💻✨🥸🍊

One of the cool things I am *really* enjoying at work right now is being able to write both the backend and frontend mobile code for particular features
It's made testing locally and the prototyping process so much faster 🚀

Got into Android completely by accident. When I left uni, I had no intention of becoming an Android developer until a recruiter called to say he'd seen my CV, we had attended the same university, and he wanted me to meet some people
Those people were the founders of bopple.com
