About Bikash Roy

Bikash Roy is the founder of Free Live Calculators and an online research specialist with over 10 years of experience cross-referencing official data sources — WHO, NIH, government agencies, and peer-reviewed standards — to ensure every calculator on this site is accurate, reliable, and up to date.

Expertise & Background

Bikash Roy brings expertise in:

• Online research methodology — systematic cross-referencing of WHO, NIH, government, and academic data to verify every formula and reference table published on this site
• SEO strategy — content cluster planning, keyword research, and organic growth strategies tailored to informational and tool-based search intent
• Technical SEO — structured data (JSON-LD), Core Web Vitals, schema markup, crawl architecture, and SERP feature optimisation
• Web development & design — front-end development (Astro, React), UI/UX design, WCAG-accessible interfaces, and high-performance static web experiences
• Business & marketing plan development — go-to-market strategy, content marketing roadmaps, and digital product growth planning

Why Free Live Calculators?

Bikash Roy launched Free Live Calculators after repeatedly encountering calculator sites that were inaccurate, inaccessible, cluttered with ads, or missing the educational context users need to actually understand their results.

The goal: build every calculator the right way — verified formula, official reference data, plain-English explanation, accessibility features, and full supporting documentation. Every time.

Verification Commitment

Every calculator on this site is personally reviewed by Bikash Roy before publication. Reference data tables are verified against primary sources. Worked examples are manually calculated and confirmed. When standards change (e.g., updated WHO guidelines), calculators are updated accordingly.
