Kishan Kumar Singh Profile Image

> I'm a Senior Full Stack Engineer from New Delhi, India with 5+ years of experience shipping production-grade web systems. I've owned entire ecosystems solo - from architecting REST APIs to clearing 12-month bug backlogs, integrating payment gateways, and automating workflows for US enterprise clients. I don't just write code; I engineer solutions that hold under pressure.

> Currently at Innostax Software Labs, I own a live SugarCRM ecosystem serving banking clients. Previously at Goolean Technologies, I built Clocktales HRMS and Oyly's full backend from scratch. I mentor developers and lead architecture decisions.

> When I'm not engineering at scale, I'm building JobPilot AI (autonomous job-hunting automation) and my cinematic portfolio - because side projects reveal who an engineer really is.
