• Designed a multi-tenant, webhook-style document notification system using AWS Serverless, supporting 100+ customers and processing 100K+ documents daily with <1 min latency, DLQ-backed retries, transformer-based extensibility, with full idempotency and observability.
• Designed a scalable, event-driven architecture using AWS Lambda, SQS, and Schedules to poll 3rd-party vendor orders across 1000+ daily active trains, reducing operational costs by 40% and enabling real-time ingestion of 100K daily orders.
• Decoupled audit persistence from core business logic by implementing asynchronous processing with SQS and Lambda consumers backed by DLQ and retries, improving reliability, system fault tolerance by 3x, and reducing downstream errors by 80%. •Architected and delivered an extensible onboarding workflow for new clients using serverless orchestration (Lambda, SQS, Step Functions), reducing manual effort and errors by 90% and onboarding time from 1 day to under 1 hour.
• Led the development of a high-performance, multi-tenant audit log dashboard built on MongoDB, with support for filters and indexed queries, enabling real-time audit visibility across systems.

• Worked on building an automation solution to create, manage and migrate alarms/monitors of services in different regions. It also serves as a one click tool to generate IaC solutions for managing existing monitors.
• Used by over 300 internal teams, thus saving close to 600 days of manual effort of creating and migrating monitoring stacks.
• Designed multi-region, failover safe and resilient AWS architectures to avoid application downtime during failure of an AWS region/service.
• Designed reusable string (parsing/filtering) and graph algorithms.
• Tech used - Java, CDK, AWS (Step functions, Lambdas, S3, SQS, ECS Fargate, Auto Scaling, DynamoDB, Redshift)

• Built a tool from scratch which generates audit reports, insights and suggestions by processing monitoring hierarchies of individual services. The insights tell the history of service's past performance based on its alarms.
• Tool has over 200 internal teams onboarded and helps in saving close to 2000 tickets per year by providing suggestions to improve the monitoring hierarchies.
• Improved the event based serverless architecture on AWS which reduced throttling of downstream services by 90%.
• Worked with graph algorithms in order to deduce insights and suggestions about the monitoring stack.
• Tech used - Java, React, Typescript, CDK, AWS (Step functions, Event bridge, Lambdas, ECS tasks, S3, DynamoDB, Redshift serverless)
