Hi, I'm a Senior Software Engineer at PayPal with over 7+ years of experience in backend development and distributed systems. I have built and optimized large-scale, high-throughput systems processing billions of events daily, with a focus on performance, scalability, and reliability. I have switched from service based company to product based company .I enjoy mentoring engineers, reviewing resumes, and helping professionals prepare for backend engineering and system design interviews. Whether you're looking for career guidance, interview preparation, or technical mentorship, I'd be happy to help.
