Pappu Kumar
Founder & Lead Developer at ToolKitHub
About
Pappu Kumar is a full-stack engineer with 8+ years of experience in web development, specializing in Next.js, TypeScript, React, Node.js, and scalable SaaS architectures. He is passionate about building privacy-respecting, high-performance web applications that solve real problems for users.
He founded ToolKitHub in 2024 after growing frustrated with existing online tool websites that were cluttered with intrusive ads, required account creation, uploaded user files to unknown servers, or simply looked outdated and poorly maintained. ToolKitHub was built from the ground up with a “privacy-first, no-upload” philosophy — all processing happens locally in the browser, files never leave the user’s device, and no account is required.
Under his leadership, ToolKitHub has grown into a free online platform with 101 browser-based tools across PDF manipulation, image editing, SEO optimization, developer utilities, writing assistance, financial calculators, and AI-assisted study aids.
