Lead Software Engineer | Product Developer | Seasoned Interviewer

10 years of experience in Software development with a good understanding of Data Structures and Algorithms. Experienced in designing and developing large-scale distributed systems with Java, Python, Spring boot and Cloud technologies (Google Cloud Platform or Amazon web services).

I've worked at Amazon, PayPal, and JP Morgan Chase, gaining extensive experience conducting coding, problem-solving, and system design interviews throughout my tenure at these companies globally.

I love to solve problems related to programming and explore open-sourced RESTful APIs. Apart from work, I have a good understanding of cybersecurity and have reported major bugs in Uber, Google, Ola, LinkedIn, and Amazon.
