Java Spring Microservices

Backend Engineering & API Development

• Design, develop, and maintain high-performance Java-based RESTful APIs and microservices serving member-facing digital products.

• Build and evolve core Member Services platform capabilities including account management, card servicing, rewards, benefits inquiry, and transaction history.

• Develop event-driven architectures using Apache Kafka for real-time member data processing, notifications, and service orchestration.

• Implement GraphQL APIs to support flexible, efficient data delivery to mobile and web front-end clients.

• Ensure API contracts are robust, versioned, well-documented, and backward-compatible across consumer teams.

Microservices & Cloud-Native Architecture

• Design loosely coupled, independently deployable microservices following domain-driven design (DDD) principles.

• Deploy and manage services on cloud platforms (AWS / GCP / Azure) using containerization (Docker) and orchestration (Kubernetes / OpenShift).

• Implement service mesh patterns, circuit breakers, retries, and rate limiting for resilient inter-service communication.
