Hi, I’m Raghav Pangasa, a Technical Lead at Paytm with over 6 years of experience in software engineering, cloud infrastructure, and AI-driven solutions. I’ve led teams in building enterprise-scale systems, from cloud cost optimization tools saving $30K+/month to cutting-edge security platforms protecting 100+ AWS accounts. My journey spans across startups and large-scale companies — from developing LiDAR-based intrusion detection systems at CRON AI to automating finance reconciliation pipelines processing 10 crore+ daily transactions at Paytm. Along the way, I’ve worked extensively with Python, Golang, AWS, DevOps, and Generative AI tools, and published research in IEEE and international journals. On TopMate, I’m here to: Help students & professionals with career guidance, resumes, and interview prep. Share insights on cloud security, AWS optimization, and DevOps best practices. Discuss Generative AI tools and how to practically use them at work. If you’re looking for honest, practical advice or want to dive into tech strategy & execution, let’s connect.
