What I'm looking for

I am looking for a collaborative environment that fosters innovation and growth, where I can leverage my skills in full-stack development and contribute to impactful projects.

I'm a Full-Stack Engineer with over 8 years of experience in solving complex frontend and backend challenges. Currently, I work as a Senior Frontend Engineer at Clarifai, where I lead the development of customer-facing AI tools using React, Next.js, and TypeScript. My focus on performance optimization has resulted in significant improvements, such as boosting Core Web Vitals by 40% and increasing organic traffic by 25% through effective SEO strategies.

Previously, I held senior roles at Airtel X Labs and ThoughtWorks, where I contributed to scalable platform development and led frontend initiatives for AI-powered analytics dashboards. My expertise spans a wide range of technologies, including Node.js, Spring Boot, and cloud-native architectures. I am passionate about mentoring and have successfully conducted workshops on reactive programming, enhancing team productivity and reducing production bugs.
