Building high-scale payment orchestration services that power authorization and capture flows for global merchants. I design and develop cloud-native microservices using Java and Spring Boot, and contribute to modernizing APIs with GraphQL and Node.js.

Work extensively with Kafka-driven event pipelines, Redis-based caching, and PostgreSQL to improve reliability, prevent duplicate transactions, and reduce checkout latency. I also collaborate on CI/CD automation using Docker and Kubernetes and build internal dashboards with React to support operational visibility.

Developed scalable backend modules and RESTful services supporting enterprise SaaS applications used by 100K+ users. Built services using Java, Spring Boot, Node.js, and C++, and optimized MySQL and PostgreSQL queries to improve performance.

Contributed to refactoring monolithic systems into modular, event-driven architectures using Kafka. Built responsive UI components with Angular and supported CI/CD automation and containerized deployments using Docker and Kubernetes.
