Engineered distributed service to automate Amazon workforce’s manual shift generation. Used CDK/Terraform toautomate infrastructure resource management, managed full CI/CD pipeline, improved system reliability withend-to-end integration tests. Project had highest visibility in org and led to $3.5 MM in savings.• Architected scalable cloud-native metric collection system using Spring boot framework and AWS services (VPC,ECS, Cloudwatch). Implemented caching to reduce upstream latency by 20%.• Integrated AWS SQS to architect a fault-tolerant queueing system to manage WFO notifications from diversesources with 99.9% uptime. Implemented robust failover mechanisms and message deduplication strategies.• Developed config management library with advanced Java concepts: multi threading, generics, streams API,enabling cross-team collaboration. Implemented DynamoDB+S3 data store, IAM for secure authentication.• Migrated legacy service to AWS Lambda based micro-service architecture. Devised a supply oriented approach tobetter utilise network occupancy which resulted in improved efficiency, reducing P99 latency by 20%.• Led refactoring efforts to improve coding best practises. Wrote Python tools to automate service config, securedencryption keys, scaled backend servers, wrote code with 100% unit test coverage using mockito, jest.• Independently deep-dived to fix critical sev-2 on-call issues involving deployments, migrations, CPU, memeory, diskissues, python/bash scripts on Linux hosts. Mentored interns to full time roles via pair programming, knowledgesharing and ping-pong sessions.• Launched Real time monitoring dashboard showcasing workgroup metrics using TypeScript, Node.js, React, Redux,HTML, CSS. The view is monitored by 20+ operational managers

• Updated phpBB’s PM system to a more modern, chat-based interface with the ability to retrieve live messages asynchronously while allowing backward compatibility with older versions.• Worked synchronously with a team via version control.
