Work Experience

Architect

DistroCart

Present - Present

Architected a 6-service microservices backend (Auth, API Gateway, Product, Inventory, Order, Payment) using Spring Boot and Spring Cloud with Eureka Service Discovery and API Gateway for centralized routing and load-balanced service communication. Implemented JWT-based authentication in a dedicated Auth Service handling user registration, login, token generation and validation using Spring Security and BCrypt password encryption. Engineered asynchronous event-driven order processing using Apache Kafka where Order Service publishes OrderCreatedEvents consumed by Payment and Inventory Services, ensuring loose coupling and reliable eventual consistency. Integrated OpenFeign for synchronous inter-service communication (Order to Inventory stock validation) and Redis caching for the Product Service, reducing database load significantly. Containerized all services using Docker with each microservice owning its own isolated MySQL database, following the Database-per-Service pattern to enforce loose coupling.

Designer and Developer

Real-Time Group Chat Architecture

Present - Present

Designed and developed a production-ready real-time group chat web application utilizing native WebSockets for bidirectional, full-duplex persistent communication channels. Engineered an event-driven Node.js backend server managing active WebSocket connections, parsing incoming message payloads, and efficiently broadcasting group communication instances with sub-millisecond latencies. Implemented dynamic DOM manipulation via modern client-side JavaScript to render text payloads instantly, handle connection state changes gracefully, and structure clean message queues.

Developer

CyberSentinel

Present - Present

Built a full-stack cybersecurity tool that classifies websites as phishing, suspicious, or benign by combining a trained ML model, VirusTotal API threat intelligence, and live DOM analysis into a unified risk score. Trained a Random Forest classifier on 640,000 URL records using URL-based features achieving high accuracy in phishing detection without requiring page content. Developed a Chrome browser extension that automatically scans the active page on load and surfaces the threat classification in real time, with an additional manual URL check option for on-demand analysis.
