About

Hi there! I’m Smile Gupta - a passionate and detail-oriented Software Engineer 2 at Wayfair, focused on building performant, scalable, and elegant UI systems. I thrive at the intersection of design and engineering, with experience across JavaScript, React, Svelte, and TypeScript. Previously at Razorpay, I played a key role in shaping the Checkout experience, leading initiatives like Magic Checkout, Quick Buy, and the Coupon Engine. These products helped improve user engagement, boost conversions, and reduce merchant churn at scale. I'm deeply invested in frontend architecture, theming strategies, and crafting reusable design systems that empower teams to move fast without compromising on consistency. 🌍 Outside of work, I’m an active community builder and lead JSlovers, a thriving JavaScript community in Bangalore. I’ve organized countless meetups, workshops, and tech talks, and love creating spaces where developers can learn and grow together. Lately, I’ve also been exploring storytelling in tech - writing about the small details and decisions that shape our frontend world. 🎮 When I’m not debugging code or speaking at events, I’m probably experimenting with new recipes or living my best life in The Sims 4. 🔧 Tech Skills: JavaScript, React, Svelte, TypeScript, CSS 💡 Specialties: Frontend Architecture, Design Systems, Code Optimisation, Theming, Testing 🗣️ Community: Speaker, Workshop Host, Interviewer Let’s connect and talk about frontend, systems thinking, or your favourite Sims expansion pack! 😊
