• Built an invite-only federated identity platform using AWS Cognito and OIDC-based SSO, reducing onboarding time from days to minutes and eliminating login friction for users. • Owned a centralized integration platform using Python (Pydantic) and REST APIs to unify multiple third-party systems into a single internal portal, improving operational workflows for 30% of the active user base. • Established production observability for backend services using Grafana across AWS Lambda and APIs, enabling real-time monitoring of health, latency, and failure metrics. • Designed a DynamoDB-based concurrency control mechanism for time-driven packet workflows in Live-ECG systems, reducing inconsistent user states and packet losses by 20% under high concurrency. • Developed backend services for a cardiac health platform in Java and Node.js, optimizing distributed data access and reducing large workout dataset retrieval times by 60%. • Led the implementation of an automated CI/CD pipeline using AWS CodeBuild and CodeDeploy, enabling repeatable deployments and reducing development turnaround time by ~70%. • Parallelized offline workload simulations using Java multithreading (threads & futures) to stress-test systems and improve reliability of Live-ECG data pipelines. • Led the migration of internal services to secure B2B APIs, replacing legacy S3-triggered Lambda workflows and improving system maintainability and partner integrations.
