The Team
The Simple Toolbox is built and maintained by one engineer. No marketing department, no outsourced blog farm — just code, published openly.
Alamzeb Khan
Founder & Editor
Spring, Texas, USA
Alamzeb builds and oversees all properties in the portfolio. He reviews tool accuracy, sets editorial standards, and is responsible for every piece of content published on this site.
Before building digital products, he spent over a decade in compliance-heavy industries — pharmaceutical sales at Merck and international automotive — where a wrong number or an overreaching claim had immediate, visible consequences. That standard carries over here.
"Free should not mean free to spy on you. Every calculator on this site runs in your browser — not because I promise not to look, but because the architecture makes looking impossible."
Focus Areas
Why one person?
Most "free tool" sites are run by content farms that publish thousands of low-effort pages, chase ad revenue, and treat accuracy as an afterthought. The Simple Toolbox is the opposite of that.
A single engineer writing every formula means one person is accountable when a number is wrong. It also means every change — a new IRS tax bracket, a revised platform fee, a corrected unit conversion — gets reviewed by someone who wrote the original code. If you find an error, you can reach that person directly at [email protected].
How We Work
- 1 Every calculator's formula is documented and cross-checked against a primary source (government agency, peer-reviewed journal, or official platform documentation).
- 2 Financial tools are re-verified each quarter when underlying constants change (tax brackets, contribution limits, fee schedules).
- 3 Blog drafts may be AI-assisted for speed, but every published post is edited and fact-checked by Alamzeb before it goes live.
- 4 Corrections are public. Every calculator page links to a methodology note showing the formula, inputs, and the date constants were last verified.

What gets priority
The first priority is correctness: broken formulas, stale fee schedules, unclear tax assumptions, accessibility issues, and privacy concerns get handled before new pages. The second priority is usefulness: every tool should answer a practical question without forcing users through signups, popups, or unnecessary steps.
The site is still young, so feedback matters. When users report confusing wording or missing context, those notes shape the next edits to the calculator instructions, examples, and FAQ sections.
