Experience
Senior Software Engineer
Feb 2024 — Present · US
Led, Designed, architected, and maintained a microservice-based, highly scalable distributed order fulfillment platform(SHIPROCKET) leveraging Java, Spring Boot, and RDBMS/MySQL to process high-volume seller orders across multiple e-commerce marketplaces. Designed and implemented an event-driven system enabling parallel processing of millions of inventory updates across 10+ global marketplaces. Replaced legacy file-drop workflows with resilient streaming pipelines and intelligent retries, cutting sync latency by 80%. Leveraged distributed cache deduplication with timestamp-based conflict resolution to eliminate overselling, supporting active sellers and millions of daily transactions since launch. Built modules for seamless shipment creation, delivery tracking, and order lifecycle orchestration. Integrated with leading third-party courier APIs (FedEx, Delhivery, Bluedart, etc.) & Ecommerce platforms (Amazon, eBay, shopify) using REST for real-time orders, shipping and tracking workflows, ensuring reliability across heterogeneous partners. Implemented event-driven architecture with Apache Kafka to manage asynchronous order lifecycle events, retries, and failure recovery with guaranteed consistency. Deployed and managed services on Kubernetes clusters across all environments with automated scaling, while monitoring health, performance, and SLAs through Prometheus, Grafana, and Splunk-driven alerting. Designed and optimized scheduled jobs, idempotent retry logic, and recovery pipelines for failed delivery attempts and delayed tracking updates. Partnered with QA and nationwide performance teams to lead rigorous load, soak, and resilience testing, proactively identifying bottlenecks and optimizing throughput for sustained high-volume traffic(soak tested for 20k TPS). Conducted 20+ code reviews weekly and mentored 2 junior engineers on microservices best practices and system design principles
