Frontend Engineer improving scalable React/Next.js products with TypeScript, performance gains, and mentorship.
IndiaWhat I'm looking for
I’m a Front-end Engineer with 5+ years of experience specializing in React.js, Next.js, and TypeScript. I build high-performance, scalable, and responsive web applications, with a strong focus on user-focused solutions and product innovation in remote and hybrid environments.
At Impelsys, I delivered measurable results—reducing project expenses by 20% while maintaining quality and improving efficiency by 25%. I also used advanced Server-Side Rendering (SSR) in Next.js to make applications faster and more responsive, and I help teams deliver complex work on time within budget.
Across my earlier roles, I optimized performance (including a 30% improvement in front-end efficiency and reduced page load times) and strengthened reliability through Test-Driven Development with Jest. I’m also deeply involved in growing others, earning the Guidance Guru Award for mentoring 5+ junior developers and conducting 10+ technical interviews to expand the frontend engineering team.
