Welcome to my kitchen! I'm Karan Kumar Gupta — a Senior Frontend Engineer who serves enterprise-grade Angular applications to Fortune 500 clients. Every dish is crafted with care, seasoned with accessibility, and plated with precision.
Every great dish starts with a great chef, and every great interface starts with someone who obsesses over the details.
I've spent 6+ years perfecting my craft in the frontend kitchen — from my early days learning the basics at Inquizity Metanoia in Mumbai, to now running the pass at DiligenceVault, where I build mission-critical FinTech applications.
My secret recipe? Accessibility-first development, a generous helping of TypeScript, a pinch of RxJS magic, and always plating for the enterprise palate. I've seasoned interfaces used by the world's largest institutional investors managing over $500 billion in assets.
Currently exploring new flavors in React, System Design, and DSA to expand the menu.
Each dish is crafted from the finest ingredients
