Background
I am a software architect with over a decade of experience designing and building enterprise-grade applications. My career has spanned banking systems, SaaS platforms, healthcare software, and e-commerce solutions across the Middle East and beyond. I hold deep expertise in .NET ecosystem, Angular, Flutter, and modern cloud architectures.
Throughout my career, I have led teams building systems that handle millions of transactions, serve thousands of concurrent users, and meet strict regulatory and security requirements. This background shapes everything I build: reliability, accuracy, and user trust are not optional features. They are the foundation.
Why I Built Smart Tools Daily
Smart Tools Daily started from frustration. Every time I needed a quick calculation, whether it was checking BMI for a health plan, finding the days between two dates for a project deadline, or calculating a percentage for a business report, I would land on websites overloaded with pop-ups, misleading ads, and questionable accuracy.
I kept asking: why is it so hard to find a clean, accurate calculator that just works? So I built what I wanted to use myself. Each tool on this site solves a specific problem I have personally encountered. The BMI calculator exists because I wanted one that clearly explains the categories instead of just showing a number. The age calculator exists because visa applications kept asking for exact years, months, and days. The GPA calculator exists because students in my family needed one that handles different grading scales correctly.
Every tool is built with the same engineering discipline I apply to enterprise software: validated inputs, correct mathematical formulas, clear edge case handling, and thorough testing across browsers and devices.
Technical Approach
I believe the best tools are the simplest ones. Most calculators on Smart Tools Daily are self-contained pages that run primarily in the browser. In typical use, calculation inputs are processed locally with JavaScript for fast results, and we do not require user accounts.
This architecture is intentional and keeps tools fast and privacy-conscious. Like most websites, Smart Tools Daily also uses analytics and advertising technologies as described in our Privacy Policy. Some tools may continue to work after initial load depending on browser caching and device settings.
On the technical side, I follow industry-standard formulas from authoritative sources: WHO guidelines for BMI categories, ISO 8601 for date calculations, and IEEE 754 for decimal precision in unit conversions. When a formula has known edge cases (like temperature conversion offsets or leap year handling), I document them directly on the tool page so users understand what is happening under the hood.
Quality Standards
Tools on Smart Tools Daily are reviewed through a structured validation process before publication and during updates:
- Formula verification: Calculations are checked against authoritative references (such as official guidelines, recognized standards, or technical documentation) where applicable.
- Edge case testing: I test boundary conditions that most calculators ignore. What happens when you calculate BMI with extreme values? What about age calculation across leap years? What if a date falls on February 29?
- Cross-browser validation: Key tools are tested on Chrome, Firefox, Safari, and Edge across desktop and mobile to ensure consistent behavior.
- Accessibility review: Proper ARIA labels, keyboard navigation, and screen reader compatibility are built in from the start, not added as an afterthought.
- Performance audit: Pages are optimized for fast loading on slow connections. No heavy frameworks, no unnecessary dependencies, no render-blocking resources beyond what is essential.
Bilingual Commitment
As a native Arabic speaker working in English-dominant tech environments, I understand the gap that exists for Arabic-speaking users online. Most calculator tools either do not exist in Arabic or are poorly translated with broken layouts. Smart Tools Daily offers proper right-to-left Arabic pages with culturally appropriate content, not machine-translated copies.
This includes Hijri calendar support in date tools, Arabic number formatting where appropriate, and RTL-aware design that respects the natural reading direction. The Arabic version is not a secondary afterthought. It is a first-class citizen of this platform.
Tools I Have Built
The tools below are products I have personally worked on, including calculation logic, content, and interface design, and I continue to review and improve them over time.
Editorial Philosophy
Content on Smart Tools Daily is written to inform, not to fill space. Every tool page includes a detailed explanation of how the calculation works, what the results mean, and where the formulas come from. I write these sections myself because I believe the person who built the logic is the best person to explain it.
I aim to avoid filler and plagiarism. When I reference medical guidelines such as WHO BMI categories or scientific formulas, I cite authoritative sources where available. When a tool has limitations (like approximate Hijri conversions), I state that clearly.
I am a software engineer, not a licensed medical, legal, or financial professional. The content and tools on this site are for informational use and should not replace professional advice.
My goal is that every page on this site could stand alone as a useful resource even if the calculator itself did not exist. The content should teach you something, not just sell you a click.
