Hi, I'm Alexandru Dessanai, the Web Developer and creator behind IstantCalc.
My goal is to bridge the gap between complex industry standards and user-friendly digital tools. As a developer, I believe that accuracy isn't just a requirement—it's the foundation of the web.
Why Trust a Web Developer?
In today's digital landscape, the reliability of online information has increased significantly, provided you know where to look. Being a Web Developer gives me a unique advantage in curating this content:
- Digital Literacy & Source Verification: I don't rely on secondary blogs. I have the technical skills to parse official documentation, government datasets, and academic papers directly. I know how to distinguish authoritative data sources from noise.
- Algorithmic Integrity: Every calculator here is built on verified mathematical formulas. I translate physical laws and official guidelines into code, ensuring the logic is precise and reproducible.
- Transparency: Unlike black-box tools, I prioritize showing the sources behind the math. If a calculation comes from a specific standard (like ISO or ANSI), I verify it against the latest digital documentation available.
Our Commitment to Verifiable Data
IstantCalc operates on a strict "Verify, Don't Guess" methodology. Every tool is built by cross-referencing authoritative databases:
- ✓ Formulas derived from official documentation (not estimates)
- ✓ Data verified against government and industry standard bodies
- ✓ Code tested for edge cases and mathematical precision
- ✓ Continuous updates as digital standards evolve
Health & Medical Disclaimer
While I rigorously verify the mathematical formulas against medical guidelines (CDC, WHO), the calculators on this site are for educational purposes only. They are software tools, not a substitute for professional medical advice. Always consult a qualified healthcare provider for personal health decisions.
Verified Sources Used
To ensure maximum reliability, I engineer these tools using data from:
- Health Logic: National Institutes of Health (NIH), Centers for Disease Control (CDC), WHO APIs.
- Construction Math: International Building Code (IBC) guidelines, ASTM International standards.
- Material Standards: Tile Council of North America (TCNA), ANSI specifications.
