Led architecture and operation of distributed backend microservices for market/analytics workflows handling approximately 100K–1M transactions per day, using independent scaling, fault isolation, and production health checks. Owned backend-first full-stack delivery across independently deployable services, secure APIs, data workflows, and React applications, translating complex customer requirements into maintainable enterprise software. Optimized API execution paths, caching, database access, and request handling to reduce latency by 30% for high-traffic link-management and analytics workflows. Built responsive React and TypeScript UIs for campaign management, analytics, exception handling, and operational review, supporting backend services with clear user experiences. Automated classification and review workflows, reducing manual review work by 40% while retaining human approval and auditable processing for sensitive decisions. Containerized microservices with Docker and Kubernete

Designed and owned Java/Spring Boot and Node.js microservices supporting supplier discovery, project intake, approvals, partner integrations, and payment workflows with secure and predictable API behavior. Built versioned REST APIs and Kafka-based asynchronous processing components for more than 500,000 daily workflow transactions, implementing idempotency, defensive validation, retry-safe processing, and consistent error handling. Developed React and TypeScript operational tools integrated with backend services to help teams investigate exceptions, coordinate suppliers, manage approvals, and resolve workflow issues. Strengthened authentication and authorization with Spring Security and OAuth 2.0, role-based permissions, encrypted communication, and careful handling of sensitive supplier information. Containerized backend services with Docker and Kubernetes and automated AWS infrastructure changes with Terraform to improve environment consistency, scalability, and deployment reliabilit

Delivered full-stack customer-facing and internal applications using Angular and React, plus Node.js and Java REST-based backend integrations. Developed reusable TypeScript components for multi-step workflows including validation, filtering, navigation, status tracking, and operational review queues. Integrated frontend applications with Node.js and Java services while maintaining secure API access and consistent error handling across account and workflow views. Improved responsiveness by simplifying state management, optimizing network requests, reducing unnecessary rendering, and efficiently handling larger result sets. Implemented real-time and asynchronous interface updates with improved loading, retry, accessibility, and error-recovery behavior across interactive workflows. Expanded JavaScript/TypeScript test coverage with Jest and investigated production regressions to improve validation across critical user journeys.
