Implemented cell-based architecture for multi-tenant isolation and cell-aware routing for improved fault tolerance.

Designed real-time organization-level insights aggregation system, achieving sub-second query performance (1.13s for 10K accounts) with 100% accurate data through optimized DynamoDB schema and Index design.

Implemented rollback-on-failure mechanisms with canary-based composite alarms, achieving zero production incidents during major service deployments across 14 AWS regions.

Developed response enhancement and preprocessing components for an LLM powered security assistant for AWS Network Security Director, tuning prompts and integrating new APIs to improve response accuracy and formatting.

Designed and implemented an automated evaluation system with metrics calculation (intent classification, function call accuracy) and reference response generation to systematically measure and improve the Q Extension agent performance

Designed database scaling strategy using dynamic sharding with random distribution for high-throughput operations.

Led AWS SDK v1 to v2 migration across 4 authentication services (WebAuthn credential management, token generation, authorization services) with zero-downtime deployment using feature flags, reducing DynamoDB query latency by 15% for a tier-1 Amazon Identity Provider service (IdPrism) that manages and authenticates third-party workforce identities.

Implemented anti-entropy drift detection mechanisms for identity management, enabling data consistency validation across distributed services with multi-region configuration support.

Built a high throughput distributed log ingestion system processing 20 million+ messages per second, implementing CloudWatch Logs subscription filters with Lambda functions to forward log events to SQS queues for parallel processing and aggregation.

Built an internal queue system with dedicated thread pools for ElastiCache write operations, implementing log eviction service with SQS-based message processing and comprehensive metrics tracking for high-volume log ingestion.

Implemented an ElastiCache integration with Redis for high-throughput log caching, implementing compression algorithms, multimap operations with connection pooling, and configurable health check intervals to support near real-time data availability (~2 minutes).

Optimized auto-scaling policies and ECS cluster configurations for peak traffic readiness, implementing isolated thread pools for operation segregation and configurable TTL for distributed cache management.

Architected an automated test account provisioning system for Alexa's load testing platform using AWS Step Functions and Lambda, eliminating manual account creation through dynamic resource allocation based on TPS requirements.

Created serverless workflow orchestration using Step Functions and Lambda for batch account provisioning, implementing Event Bridge callbacks, task tokens for long-running operations, and automated ticketing for large-scale requests (25K+ accounts).

Led comprehensive API migration for Alexa Test Accounts and Devices Service (rename, deregister, register operations), including role-based authorization framework with upstream API integration.

Developed (Backend-Frontend) a Security Dashboard to display vulnerability data and security posture of Autodesk products.

Built REST APIs to integrate infrastructure and application vulnerability scan data from different scanning tools to provide

Built a scalable data pipeline to process, store and publish real time vulnerability data for Autodesk products.

Optimized data ingestion and import from infrastructure scans by 37% leveraging multithreading and multiprocessing.

Built a chat interface to consider user-based feedback and provide additional choices to provide user-specific search results.

Created hybrid cross-platform mobile applications for Android and IOS to display revenue stats and KPIs of a company.

Developed a form builder web application to generate a form based on custom labels and types provided by a user.
