Swastik Kotwal

I’m a Web Developer focused on building modern, scalable web applications with JavaScript and TypeScript, especially through React and Next.js. I enjoy turning requirements into responsive, user-friendly interfaces while strengthening fundamentals in performance, reliability, and modern web architecture.

In client-facing production work, I’ve implemented JavaScript interactivity for form handling, DOM manipulation, and dynamic rendering, and customized storefronts and business sites through theme-level frontend changes. I’ve shipped improvements directly to live environments, improving mobile responsiveness, layout consistency, and cross-browser compatibility while working closely with designers and stakeholders.

As a founding team member, I built and maintained a scalable Next.js + TypeScript frontend serving 40,000+ users in 30 days. I also resolved critical booking-flow and API integration issues, improving visual consistency and targeting Core Web Vitals through ongoing performance and mobile responsiveness work; I built reusable UI components and integrated GraphQL APIs to power listings and booking workflows. Beyond web, I’ve worked on a decentralized credential verification project and a therapy web app with secure chat and real-time video via WebRTC.
