Saurabh Chamedia

• Led engineering strategy and initiatives for Insurance business (Connected Accounts, Unauth, KarmaDrive) post-Zendrive acquisition, aligning technical direction with business goals.
• High-Scale Architecture: Evolve and maintain resilient backend services handling 30M+ daily calls for a massive user base of 130 million members.
• Led migration of critical datasets from MySQL to Google Spanner, improving global scalability and data integrity for Life insurance business.
• Optimization & Efficiency: Drive technical roadmaps that reduced API latency and optimized cloud storage costs across GCS and Google Spanner.
• Mentored high-performing team, defined engineering standards (SLAs/KPIs), and owned end-to-end design lifecycle for complex, cross-functional features, enhancing team capabilities.

• Ingestion Layer Innovation: Designed and implemented a high-performance packet ingestion layer from the mobile SDK to the backend to manage ingestion at a scale of 60 Million trip packets/day.
• System Redesign for Scale: Redesigned the backend architecture for the IQL product to support a target of 100M MAU and 60M trips per day across multiple major publishers.
• Scalability Testing: Partnered with cross-functional engineers to conduct scale testing, translating bottlenecks into successful system redesigns and implementations.
• Cost-Optimized Design: Prioritized cost-efficiency in architectural choices to manage the financial impact of processing massive datasets.
• Technical Mentorship: Provided guidance and mentorship to junior and mid-level engineers on distributed systems and high-throughput processing in AWS cloud.

• Business Expansion: Led backend design and implementation for new Commercial Lines (CL) business, enabling beacon-based vehicle identification and real-time trip analytics dashboards that support customer engagement.
• Critical Data Migration: Spearheaded the live, data-heavy AWS RDS major version upgrade for mission-critical databases supporting the entire business with zero downtime.
• Feature Development: Delivered core functionality for Fleet and CL customers, including geofence monitoring, trip

deduplication, and enhanced reporting tools.

• Legacy Migration: Migrated AWS Infrastructure Budget System from a monolithic system to a new microservice architecture on AWS, leading to legacy deprecation.
• Workflow Automation: Developed an automated approval system for server orders using AWS Step Functions, reducing approval time from 4 days to 0.5 days.
• Data Pipelines: Built an Approval Recommendation System for EC2 orders using Java, Lambda, and Kinesis, reducing approval time by 60% from 10 to 4 days reducing offer fulfillment time.

• Sql to NoSql Db Migration: Migrated service database from Oracle to AWS Dynamodb. Solved problem of syncing data from NoSql DB to multiple downstream consumers by implementing Fanout pattern using AWS Lambda. This resulted in decoupled architecture with only one service managing primary DB. Service had global presence with 18 API's, 150 prod clients & avg 350 read & 10 write TPS.
• Regional Compliance: Leveraged Java reflection to implement API interceptors for regional encryption standards for database, preventing code duplication and ensuring cleaner implementation.
• Leadership: Actively reviewed peer code and design for the entire project to maintain high engineering standards.

• Payment Validation: Built a payment data validation system using the Drools rule engine, leading to a 90% reduction in vendor payment failures.
• Notification Systems: Designed and developed a secure notification system based on AWS SQS and SNS with attribute-based event filtering.
