Himanshu Sharma

Full Stack Engineer · Bengaluru

I build production systems that outlive the vendors they replaced.

React and Node.js in fintech. At Groww I own the scheduling platform, the lead pipeline, and the AI workflows around them. Before that I replaced our WhatsApp vendor end to end at Fisdom.

About

“I like the unglamorous middle — token refreshes, retry queues, routing rules — because that is where systems actually live.”

Tezpur CSE '25. C-DAC-trained mobile dev. Fintech by accident, now by choice. Every system I ship, I stay to run — which is how vendor replacements become platforms.
