Hey, I’m Lazar Nikolov
I’m a software engineer and content creator. I publish videos and live stream on YouTube, and also run a Discord community called creatures.sh. I live in Toronto, Canada.
I currently work at Sentry as a Developer Advocate, focused on web performance, debugging, and good software engineering practices in general.
Before Sentry, I lived in Skopje, North Macedonia, which is where I’m from, and worked as a software engineer since 2015.
I’m curious by nature, and love to tinker with different frameworks and languages.
