About

I'm Andrii, a Python backend developer and founder of CodeGrain. I build practical tools for people who need to work with files without giving up privacy. My current project is CodeGrain Private Tools — browser-based PDF, image, and file utilities where files are processed locally and never uploaded to a server. I care about simple products, fast workflows, and privacy-first software that does not require an account just to solve a small task.
