About

Hi,

I'm a 4th-year B.Tech CSE student with real MERN stack projects in production. My strongest work: a full CRM system (LeadFlow) with 10 REST APIs, Chart.js analytics, and CSV export — live on Vercel. Plus a JWT-authenticated loan system with role-based access for 2 user roles — also deployed.

I'm not here for a certificate. I want to work on real product features, go through actual code reviews, and contribute from week one.

Live projects: leadflow-crm-two-umber.vercel.app

Available immediately. Open to remote or relocation.

Experience

I have hands-on experience with JavaScript, React, Git, and Node.js, having built several full-stack applications using the MERN stack. My proficiency with these technologies is at the "built projects" level. I am currently learning TypeScript and Next.js and have a good understanding of their fundamentals, although I have not yet developed major projects with them.

The most substantial project I have built is LeadFlow CRM, a Lead Management System developed using React, Node.js, Express.js, MongoDB, JWT, and Axios. I worked as the sole full-stack developer and was responsible for designing and implementing the entire application from scratch.

The system includes secure user authentication with JWT and bcrypt, RESTful APIs for lead management, and a responsive dashboard for viewing and tracking leads. I implemented CRUD operations, lead status management (New, Contacted, Qualified, Converted, and Lost), search functionality, pagination, and statistical insights. I also integrated MongoDB for persistent data storage and used Git and GitHub for version control and project management.

This project provided me with practical experience in full-stack development, API design, authentication, database management, and building scalable web applications.
