Osman Rahimi

My name is Osman Rahimi, and Arogun started with a simple frustration: I could never find financial tools that were accurate, transparent, and easy to verify.

When I was running my own business, I wanted to truly understand taxes instead of relying on generic advice. So I sat down with a tax advisor, learned the system step by step, and built my own templates to calculate everything myself.

Over time, that turned into a habit. I handled taxes, optimized budgets, and helped other people better understand their finances. I realized that most people don't struggle with math — they struggle with tools that hide the logic behind the results.

Arogun is my answer to that problem. Every calculator here is built the way I wish financial tools worked: clear formulas, transparent explanations, and results you can fact-check yourself. These are the same tools I use to plan my own finances, and I built them so anyone can make confident, informed decisions — without accounts, paywalls, or hidden logic.
