What I'm looking for

I'm looking to lead or build industrial IoT, edge automation, and full-stack products where I can deliver scalable cloud-to-device architectures, solve complex operational problems, and drive projects from conception through deployment.

At Cognizant, I lead industrial IoT and automation delivery for WestRock, Lexmark, and UPS. I configured 300+ Telit Edge Gateways across 15+ facilities, built a multi-protocol edge translator for 500+ field devices, and helped reduce warehouse transit times by 25%.

I've also built AWS IoT platforms for 300+ cloud-kitchen appliances, embedded firmware for smart-home devices, and independent full-stack tools including Srujan and Granthalaya. My work spans Python, C++, JavaScript, cloud platforms, edge hardware, computer vision, and industrial protocols.
