Cover image for FinSense - AI-Powered NPA Prevention

FinSense - AI-Powered NPA Prevention Platform for Banking AI-powered, post-disbursement loan health monitoring system built for SBI-scale banking use cases. Continuously monitors borrower financial behavior after loan disbursement, scores risk on a 0–100 scale across 4 tiers using XGBoost with SHAP-based explainability, and deploys a conversational AI agent to proactively engage at-risk borrowers 60–90 days before default — instead of only scoring creditworthiness at application time like traditional systems. Built the FastAPI backend (loan, risk, agent, and dashboard routers), automated risk re-scoring via Celery + Redis, and real-time dashboard updates via WebSockets, with a React + Tailwind frontend for officer-facing risk visualization.

Cover image for Role: Backend Developer (Node.js, Express.js,

Role: Backend Developer (Node.js, Express.js, MongoDB, REST APIs) ScrapBag is a startup that enables users to sell scrap online through a seamless pickup and payment experience. I was responsible for developing the backend services that powered the customer platform as well as the internal fleet management system. For the customer application, I built scalable REST APIs for user authentication, scrap pickup requests, order management, and wallet transactions. When a user scheduled a scrap pickup, the system automatically created an order and assigned it to the operations workflow. I also developed the backend for the fleet management platform used by drivers and field executives. Each driver was associated with a vehicle and could view assigned pickup requests, navigate their collection route, update pickup status, and mark orders as completed in real time. Once a pickup was successfully completed, the backend calculated the scrap value, updated the order status, and automatically credited the customer's account with the corresponding amount. This ensured a smooth end-to-end workflow from booking a pickup to receiving payment.

Cover image for I developed a modern CRM

I developed a modern CRM platform that helps businesses manage leads efficiently through a centralized dashboard. The application enables users to organize their sales pipeline, upload lead data in bulk, and quickly search, filter, and manage customer information. I built responsive and reusable user interfaces using Next.js, React, and Tailwind CSS, with a strong focus on performance and user experience. The platform leverages Server-Side Rendering (SSR) for improved SEO and faster page loads, while code-splitting and lazy loading reduce the initial JavaScript bundle for a smoother experience.
