About

Hi, I’m Arnab, an aspiring product manager and an experienced software engineer with a passion for developing scalable backend systems and driving impactful technical initiatives. My journey into technology started with an eagerness to understand how robust engineering can solve complex business problems, evolving into a commitment to building secure and efficient software solutions. With a Bachelor’s degree in computer science and an ongoing Master's in Management of Technology at NYU, I have gained solid expertise in programming fundamentals like Data Structures, Algorithms, Distributed Systems, and Software Architecture. My professional journey at Juspay has provided me the opportunity to lead significant projects including RBI-compliant network tokenization, scalable refund systems, and hybrid database architectures, resulting in measurable impacts such as enhanced security, improved reliability, and increased revenue. I'm a collaborative team player with strong communication skills, enabling me to lead cross-functional teams effectively and consistently deliver results. My proactive approach has also earned recognition through securing a patent for innovative software using facial gesture-based cursor control. I strongly believe technology is as much about collaboration and creativity as it is about innovation. If you’re interested in discussing technology, exploring collaborative projects, or exchanging ideas about product management and software engineering, I’d love to connect!
