About Me

Passionate about building scalable, user-centric applications

I'm Rajat Jerry, a Senior Full Stack Software Engineer with a passion for crafting elegant solutions to complex problems. With over 4.5 years of experience at prestigious MNCs, I've had the opportunity to work on diverse, high-impact projects spanning eCommerce, CRM platforms, and Telecom solutions.

My journey in tech started with a deep fascination for how systems work together. I quickly realized that the most rewarding work happens at the intersection of frontend artistry and backend robustness—where technology truly serves users.

Over the years, I've consistently delivered 15+ projects that have enhanced user experiences and driven business growth. I believe in writing clean, maintainable code, fostering collaborative teamwork, and staying curious about emerging technologies.
