Ibrahima SALL

I’m Ibrahima Sall, a software engineer and solo founder. I spent 15 years in logistics, taught myself to code at 30, and now run Busy Engi while shipping Freelanzi on the side. I build the freelance tools I couldn’t find — starting with Invoiciz, a simple invoice generator with no signup wall.
