• Applied Spec-Driven Development with Kiro alongside Claude/MCP AI workflows to architect, generate, and validate backend implementations, API contracts, and CDK infrastructure. • Built an automated cost-saving system that scales down idle cloud servers (ECS) and switches unused DynamoDB databases to pay-per-request mode, saving $154K+/month in infrastructure costs. • Engineered distributed state machines in AWS Step Functions with concurrency controls, eliminating duplicate executions across 5 monthly incidents and saving 15+ triage hours/month. • Built self-healing automated rollbacks in Java/Lambda using state-aware validation, slashing MTTR from 20 minutes to near-zero for failed DynamoDB live-migration workflows. • Implemented real-time CloudWatch telemetry validation in migration pipelines, verifying zero customer ingress before teardown to protect 100% of fleet migrations against outages. • Automated credential validation using AWS STS/Lambda and configured fine-grained access control (Secrets Manager/KMS) on 10+ OpenSearch domains, cutting 5–7 monthly support tickets. • Modernized build and release pipelines across 5 core services, resolving stale dependency trees and deprecating 3,485 package versions to unblock stalled deployments.

• Led pipeline health maintenance, raising the overall score from 80% to 100%. Optimized automated deployments, improved version set freshness, and ensured timely resolution of production blockers. Enhanced integration test coverage and reduced overall inventory age, resulting in a more efficient and stable production pipeline. • Partnered with the cross-team Delphi to expand Sapien's reach to external vendors. Developed guardrails for detecting blocked words in user queries and implemented a bot management system (ANDON_CORD) using DynamoDB to disable bots with unexpected behavior. Integrated Amazon Comprehend for multilingual conversations. Designed and executed end-to-end integration and load testing at 5 TPS with pytest, achieving 80% unit test coverage across all scenarios. • Developed an automated workflow for Lost Featured Offer (LFO), reducing 1.6 HC for 2,000 retail users. Stitched together 6+ APIs and implemented jsontata scripts to reduce latency, boosting performance and contributing to UAT feedback integration. • Designed and implemented backend APIs using java for the “Training Center UI,” enabling the internal sciences team to simulate conversations and collect datasets from S3 for training LLM models. Ensured 100% JUnit coverage and integrated AWS services like Lambda, S3, and API Gateway.

About

I'm a Software Engineer at Amazon with nearly 4+ years of experience building scalable backend systems and cloud-native applications. I specialise in Java, Spring Boot, AWS, and Dagger, with hands-on experience designing and developing backend services, REST APIs, and reliable distributed systems. I enjoy solving complex engineering problems, building high-performance software, and delivering scalable, maintainable solutions. Before Amazon, I worked at HighRadius, where I developed enterprise SaaS applications and strengthened my foundation in backend engineering and software development. Core Skills: Java • Spring Boot • AWS • Distributed Systems • REST APIs • System Design • SQL • Git • CI/CD I'm always open to connecting with engineers, recruiters, and hiring managers to discuss backend engineering, distributed systems, and Software Engineer opportunities.
