• Design, develop, and optimise high-performance Go-based microservices, essential to transaction management and payment processing.
• Push the boundaries of CockroachDB with efficient database configurations and high-performing queries to support scalability and speed.
• Optimise inter-service communication using NATS for low-latency and distributed processing.
• Continuously refine services to balance cost-efficiency with high performance, maintaining strict availability and performance SLOs.
• Maintain high availability standards in a Kubernetes multi-cloud environment, operating across AWS, Azure, and GCP.
