Software Development Engineer @ Amazon | Backend & Distributed Systems | Java, Spring Boot, Python, AWS | GenAI: LLMs & RAG | Ex-Research Intern @ IIT Guwahati

About

I'm a Software Development Engineer at Amazon, building and running backend services that handle millions of requests a day. My work sits where backend engineering, AWS cloud infrastructure and applied GenAI meet. What I work on • Backend & distributed systems: Java, Spring Boot, Python and FastAPI microservices on AWS ECS/EKS, designed for high availability and fault tolerance • API performance: RESTful API tuning with Redis caching, SQL query optimization and connection pooling across MySQL and DynamoDB • Cloud & automation: event-driven workflows on AWS Lambda, Step Functions and CloudWatch; CI/CD with Docker, Jenkins and Git • Applied AI: LLM and RAG-based internal services that automate log root-cause analysis and ticket routing • Full stack: internal dashboards and tools built with React, Node.js, Express and MongoDB Selected impact at Amazon • Improved service reliability by 30% by redesigning backend services for high availability • Cut API latency by 20% on services serving millions of daily requests • Reduced manual operational work by 40% through Step Functions and CloudWatch automation • Maintained a 99.9% deployment success rate with automated testing and zero-downtime rollbacks • Mentor junior engineers and contribute to HLD/LLD design reviews and code reviews Before Amazon, I was an AI/ML Research Intern at IIT Guwahati, applying PyTorch models to Bose-Einstein Condensate simulations and improving predictive accuracy by 30%. I hold a B.E. in Computer Science and Engineering from VTU (CGPA 8.68/10). Core skills: Java · Spring Boot · Python · FastAPI · REST APIs · Microservices · System Design · Distributed Systems · AWS · Docker · Kubernetes · CI/CD · SQL · DynamoDB · Redis · Kafka · LLMs · RAG · LangChain · React · TypeScript Open to conversations about Software Engineer, Backend, Full Stack and Applied AI roles.
