• Optimized the operational cost by 70% by outlining API endpoints via Django (Python) and SQL Admin Dashboard with the help of OAuth2 Authentication, AWS S3 and AWS RDS, AWS EC2 enabling admin to manage static as well as dynamic customer data.
• Pioneered the adoption of video-on-demand features to reduce operational cost and increase client engagement by 60% by integrating Cloudfront, AWS Lambda and MediaConvert for streaming content on Flutter App. Integrated Google sign-in and Razor-Pay in the app

Designed an automated logging tool that uses LLMs to predict optimal log placements in Java programs. Generated contextually relevant log statements without modifying the existing code structure. Enhanced software observability and developer productivity, outperforming existing techniques based on BLEU and ROUGE metrics

A secure, token-based e-commerce application built with Angular and Spring Boot, featuring modular services including product service, cart service, user service, admin service along with RazorPay integration for seamless payments.

Engineered a predictive auto scaling framework using LSTM to forecast CPU usage from Prometheus metrics, enabling proactive scaling on Kubernetes EKS clusters. Developed a resource pressure model linking CPU usage to SLO violations (failure rate), optimizing node allocation to maintain failure rate under a 15% threshold. Enhanced scaling decisions beyond traditional metrics by incorporating failure rate predictions, improving reliability for read/write-heavy RAG workloads designed using Flask, PostgreSQL and PgVector.
