About

I lead the hardware and electronics function at Ossus Biorenewables, where we build electroactive microbial reactor systems for green hydrogen generation and industrial effluent treatment. I joined as the first and only Power electronics engineer, and over 5 years built a team of 8 across embedded, IoT, hardware, PLC automation and cross-functional engineering. I've personally designed and deployed systems at Tata Steel (Jamshedpur), ONGC (Mehsana), Eternis Fine Chemicals (Pune), and Sayaji Maize Products (Ahmedabad). On the power electronics side, I design custom Electrode Power Units — from 40A to 160A per channel — that replaced expensive off-the-shelf alternatives at 55% lower cost. I also led the migration from Arduino/NodeMCU-based automation from the initial days to Siemens PLC, building the entire PLC capability in-house from scratch. My background is in power electronics (M.Tech, BMS College of Engineering) with hands-on experience in circuit design and debugging, PCB design, and building fully automated pilot plant systems from lab prototypes to on-site installation and commissioning. I have always thrived under great leaders and tight-knit teams. I want to keep doing that while solving real, meaningful problems.
