Owner Message

It feels truly wonderful to be recognized as a Topper in Mechanical Engineering by NPTEL, under the esteemed guidance of IIT Kharagpur. This achievement is not just a personal milestone — it is a reflection of how structured learning, discipline, and curiosity can transform one’s life and career. When I began this journey, my goal was simple — to learn, apply, and innovate. Through every lecture, assignment, and project, I realized that knowledge is most powerful when shared. At Nextra, we build bridges between education and enterprise — empowering students, engineers, and MSMEs to automate, optimize, and grow using technology. This NPTEL recognition from IIT Kharagpur inspires me to continue building solutions that merge engineering excellence with intelligent automation, so that every learner and entrepreneur can benefit from structured guidance and open innovation. I extend my heartfelt gratitude to the NPTEL team and IIT Kharagpur faculty for their exceptional teaching and mentorship. Together, let’s make learning not just a path to success — but a way to empower industries and transform futures.

Thank you.
