01. About Me

I'm a Senior Software Engineer with nearly 3 years of experience at CleverTap, one of the leading customer engagement platforms. My journey in tech has been driven by a passion for solving complex problems and building scalable solutions.

I specialize in backend development, data security, and large-scale system optimization. Throughout my career, I've had the opportunity to work on critical projects that directly impact millions of users and contribute to significant business growth.

Beyond coding, I'm passionate about mentoring junior developers and have successfully led teams to deliver multiple projects. When I'm not programming, you'll find me playing chess (I'm FIDE rated!), hiking, or enjoying a game of football or badminton.
