Frontend developer specializing in React and TypeScript, delivering high-performance SaaS and real-time web apps.
NepalWhat I'm looking for
I’m a Frontend Developer with 3+ years of experience building scalable SaaS and real-time web applications using React and TypeScript. I focus on performance optimization, component architecture, and cloud-based deployments on AWS.
At GUMP (Genese Solutions), I developed a multi-tenant mass mailing SaaS with secure client isolation and built a high-performance single-page application that improved page load time by 30%. I also created a drag-and-drop email template builder with GrapesJS and delivered real-time analytics dashboards to improve delivery visibility and decision-making.
Previously at Varosa Technology, I built and maintained real-time VoIP and logistics tracking applications using Twilio/WebRTC and REST/GraphQL integrations. I strengthen code quality through Vitest + React Testing Library, and I mentor junior developers through code reviews and pair programming.
