About me

I'm Suman Malik, a full-stack developer and product builder from West Bengal, India. I like building practical systems: ecommerce apps, dashboards, PWAs, backend APIs, Firebase architectures, Cloudflare-native apps, SaaS tools, and automation workflows. My work sits between code and business: not just making screens, but designing flows, permissions, databases, notifications, deployment, scaling, and real-world edge cases.

How I build

Understand the business flow

Design roles, data, and edge cases

Build frontend and backend together

Add auth, permissions, and notifications

Iterate from real use

Have an idea? Let's turn it into a working system.

Tell me the business flow, the roles, and the constraints. I can help shape the frontend, backend, dashboard, auth, deployment, and product architecture into something users can actually use.
