Owned features end-to-end from technical design through production operations, driving reliability, cost e ciency, and long-term maintainability.

Mentored junior engineers and contributed to design reviews, code quality, and operational best practices Amazon: International Automotive (SDE-II), Bangalore, India June 2020 { May 2022

Build complex systems from writing block diagram to launching it in 15+ countries, Migrated some batch jobs handling 500+ TBs of data into the real time processes.

Demonstrated engineering excellence and operational excellence in feature delivery Indian Oil Corporation Limited: Information Systems (Senior Software Engineer) Jul 2013 { Jun 2020

Responsible for end to end development and managing web-based solutions for business problems. Designed and developed various ERP applications in Indian Oil for more than 10,000 users spread across Pan-India . Projects

Centralized Data Deletion & Privacy Compliance Platform (Amazon Shipping):

Designed and implemented a centralized deletion orchestration platform to process customer-initiated data erasure requests across Amazon Shipping services, ensuring GDPR and CCPA compliance at scale.

Led cross-team design reviews to resolve complex authorization, identity-mapping, and data-ownership scenarios, including multi-role users, shared accounts, and cross-service identi ers. Ship Now { Shipping Platform Integration:

Designed and implemented orchestration APIs to integrate third-party shipping platforms with internal systems, abstracting partner-speci c complexity behind stable interfaces and canonical data models.

Built fault-aware work ows for request routing, error normalization, and response translation, owning the integration end-to-end as an away-team engineer from design through production rollout. Common Data Ingestion Platform:

Designed and led a centralized, event-driven data ingestion platform to unify fragmented pipelines across multiple business systems, enabling near real-time ingestion (using Spark) and fan-out of high-volume data from DynamoDB Streams, Kinesis, SQS, and S3.

Standardized ingestion patterns, schemas, and routing to support diverse downstream consumers (ElasticSearch, data warehouses, noti cation systems), reducing duplicate engineering e ort and accelerating onboarding of new data producers by approximately 40{50%.

Self-Service Onboarding Reset Feature (Amazon Shipping):

Designed and implemented a self-service onboarding reset feature (UI and backend) enabling shippers to update or correct application data, revisit declined options such as rates, and continue onboarding without customer or technical support intervention.

Redesigned backend state-management work ows and introduced safe, idempotent reset APIs to ensure consistent progression across dependent onboarding systems.

Increased shipper conversion, protected revenue by preventing waitlisted drop-o s, and reduced onboarding-related support tickets by approximately 30{40%.

Budget Consolidation Engine (BCE):

Led the design of a serverless nancial budgeting platform serving as the system of record for project budgets, transforming approved funding requests into consolidated, auditable budgets.

Built API-driven services using API Gateway and AWS Lambda to create, update, version, and archive budgets while enforcing complex business rules across capital versus operating expenses, currency normalization, and ownership controls.

Evaluated compute architecture trade-o s between functions and containers, delivering a scalable, pay-per-use solution while preserving exibility for future integration with procurement and nance systems. SHIELD{Nazir Real-Time Data Integration Platform:

Led the design of a serverless, event-driven CDC pipeline (AppFlow ! EventBridge ! Lambda) to synchronize SHIELD (Salesforce) project and site data to Nazir in near real time.

Built fault-tolerant processing and recovery using retries, SQS dead-letter queues, event archival and replay, and back ll pipelines to ensure data consistency.

Drove architecture trade-o s and cost optimization, delivering a fully serverless solution at approximately $6/month IMR while scaling within AppFlow (100GB) and EventBridge throughput limits. Check t { Automotive Fitment Experience:

Designed and delivered a customer-facing tment widget on Amazon detail pages enabling customers to validate automotive part compatibility by selecting vehicle make and model, launched across 8 marketplaces with expansion to 6 additional regions. [Published Link]

PartFinder { Automotive Search Experience:

Built a UX enhancement widget on Amazon search pages that captures customer vehicle data to lter incompatible automotive products, improving search relevance and conversion across 14 marketplaces. [Published Link] Automotive UI Components Library:

Designed a microservice-based library of reusable frontend UI components using a composition pattern, enabling consistent automotive marketplace experiences and accelerating delivery of 3 marketplaces with only 3 months of SDE e ort.

HotWire Migration of Customer Garage Data:

Designed and delivered backward-compatible APIs to migrate customer garage data between schemas using HotWire, enabling zero-downtime migration across automotive systems. [Published Link] Technical Skills

Programming: C#, C++, C, Java, VB, Python, scala

Technologies: AWS, Amazon properietry frameworks, Intellij, Visual Studio, IIS, Git Databases: DynamoDB, Sable, Oracle, SQL Server, MySQL Achievements

Recognized by Amazon leadership for delivering global Automotive UI Components library which can be used across Amazon for building front end customer experience for use cases not limited to retail only.
