I’m a results-driven Full Stack Software Engineer with 2+ years of experience designing and delivering scalable, cloud-native distributed systems. I focus on building high-quality, testable, and maintainable software while rapidly learning and integrating new technologies across the full development lifecycle.

At Audilytics Solution Pvt. Ltd., I architected and built the Incident & Fraud Management System (IFMS), a production-grade platform used by enterprise clients. I designed Spring Boot microservices with domain-driven design, and created a Kafka-based real-time notification pipeline that reduced alert latency to sub-second.

I integrated Keycloak for OAuth2/OpenID Connect SSO and fine-grained RBAC, protecting REST endpoints with JWT validation at the API gateway level. I also containerized services with Docker and authored Docker Compose configurations, reducing environment setup time by ~70%.

Before that, at Food-X, I developed and maintained backend services using Node.js and Express.js for a high-traffic food-tech platform—improving stability and reducing critical bug count by 40%. I built REST APIs with pagination and payload optimization, and used AWS services like Cognito, S3, and DynamoDB to support secure access and low-latency data access.
