Become a sponsor to Szymon Chmal
Hi, I'm Szymon! 👋
I'm an Expert Software Engineer at Callstack. My days are spent deep in the code, building and maintaining tools for the open-source community. Specifically, I am the creator and maintainer of Rozenite, Voltra, Harness, and React Native Grab.
I am incredibly fortunate that I get paid to work on these projects on a daily basis. So, you might be wondering: why sponsor me?
If my work has saved you hours of debugging, made your own projects run smoother, or helped your business succeed, sponsoring is a wonderful way to say "thank you."
More importantly, your sponsorship is the ultimate motivation for me to close my work laptop at 5 PM, only to open my personal laptop later that evening. Your support directly fuels the personal time, late nights, and weekend hours I pour into exploring new features, optimizing performance, and pushing the boundaries of what this ecosystem can do.
Let's build better software together!
