@[email protected]Hi, I’m Nik. 👋 I live in Los Angeles, California ☀️ with my wife ❤️ and our cats and dogs 🐾.
I’m a software engineer working primarily with Python 🐍, and am the @pybeach founder 🏛️ and a @socalpython organizer 🎤.
I do indoor rowing 🚣♂️, ride bicycles 🚴♂️, pretend to read 📖, pretend to write 🖋️, listen to too many podcasts 🎙️, and still wear a mask 😷 because COVID isn’t over 🦠.
I often put bonus content in media alt text 🖼️.
