I built a multi-tenant SaaS invoice and payment automation platform with a React.js frontend, a Node.js and Express.js REST API, and MongoDB. I implemented JWT authentication and integrated Stripe, SendGrid, and Twilio to support billing and business communication workflows.
For the AI-First CRM — HCP Module, I built a Python and FastAPI system that turns free-text inputs into structured records using a LangGraph workflow. I also developed its React.js frontend and JWT-authenticated REST APIs backed by PostgreSQL.
As a Python Developer Intern at Cognify Technologies, I built Python backend modules with REST API integrations and SQL workflows, resolved production bugs, and refactored endpoints to remove redundant database calls. I also built Travel Unbounded’s admin portal, CMS, and analytics dashboard.
