Full-Stack Developer building Bharat Enterprise, a business-operations SaaS shaped by real workflows and user feedback.

India

Message

I independently developed Bharat Enterprise, a business-operations SaaS built from a pharmaceutical distributor’s requirements. A real user adopted it during development, and their workflows and feedback shaped its later releases.

I expanded the product beyond billing to include inventory, customer ledgers, purchasing, analytics, subscription plans, and role-based access. I also improved ageing-report payload size from 2.3 MB to about 5 KB by moving calculations and pagination into MongoDB aggregation.

On Accountly, I evolved a personal-finance codebase into a collaborative contribution-tracking platform for an event budget, with transparency dashboards and controlled financial visibility. I’m a BCA (Hons.) student and work with React, Node.js, Express, and MongoDB.
