We focus on modernizing complex back-office systems to create scalable, secure, and high-performing platforms that streamline operations for our clients. As part of our strategic growth, we are focused on platform modernization — transitioning legacy systems to modern, cloud-native architectures that support the scalability, reliability, and high performance of core back- office functions in the insurance domain.

Key Responsibilities:

• Develop and maintain scalable front-end components using React.js and TypeScript.
• Convert UI/UX designs into responsive, cross-browser compatible web pages using HTML, CSS, and JavaScript.
• Configure and optimize Webpack for bundling, code splitting, and asset management to improve build performance.
• Develop and maintain unit tests for React components using Jest and React Testing Library.
• Collaborate with back-end developers to integrate APIs and services, occasionally working with Node.js on server-side logic.
• Identify performance bottlenecks in React.js applications, including slow rendering, inefficient data fetching and other issues.
• Utilize performance testing tools (e.g., Lighthouse, Chrome DevTools Performance tab, JMeter etc) to measure and analyze front-end performance metrics.
• Collaborate with front-end developers to optimize React.js code for performance, including component optimization, memorization, and virtual DOM diffing.
• Monitor application performance in various environments, including development, staging, and production.
• Analyze test results, identify trends, and provide actionable recommendations for performance improvements.
• Work with DevOps teams to integrate performance testing into the CI/CD pipeline. o Document performance testing processes, methodologies, and best practices.
