Background
Jobi Cheriyan is the founder of FitMetricLab and runs the platform out of Brightscale Labs Limited, a company registered in England and Wales. His focus is the technical foundation of the site — making sure every calculator loads fast, runs locally in your browser without sending personal data anywhere, and stays reliable across devices.
Jobi’s engineering background spans modern web development (JavaScript, React, and the Astro framework that powers FitMetricLab), workflow automation in Python, and cloud infrastructure on Cloudflare. The architecture goal is simple: keep the tools genuinely useful for everyday people without compromising on speed or privacy — the calculators run client-side, with no server round-trips and no tracking of the numbers you enter.
On the editorial side, Jobi sets the standard that every calculator on FitMetricLab must show its working, name its formula, cite its primary source, and avoid the prescriptive or salesy language that fitness sites often slip into. The site exists to help people understand the numbers behind their training and health metrics — not to sell them anything.
FitMetricLab is operated by Brightscale Labs Limited (Company No. 16990009). The platform is not a medical, nutritional, or coaching provider — every tool is explicitly educational, and personal health or training decisions should be discussed with a qualified professional.
