Shiv Kumar

I’m a full stack software engineer with strong expertise in building production grade SaaS and e commerce platforms, with a focus on scalable backend systems and clean, reliable frontend interfaces.

I’ve led the development of Threadfactory, a B2B apparel marketplace and operations platform, where I designed and built end to end solutions including backend APIs, authentication systems, complex order workflows, and operational dashboards. The platform supports multiple user roles and applications using centralized authentication admin login + OTP based access and scalable data architecture.

My backend expertise includes Node.js, TypeScript, Payload CMS, MongoDB, REST APIs, JWT/OTP authentication, and performance optimized database design. On the frontend, I work with React and Next.js to build responsive dashboards and user interfaces aligned with real business workflows.

I’m comfortable owning features end to end—from system design and implementation to deployment on AWS
