• Integrated Kong API Gateway to optimize microservices architecture, enhancing system performance with custom authentication and rate-limiting capabilities, reducing latency by 30%.
• Implemented Prometheus and Grafana integration for real-time monitoring of Kong API Gateway, enabling cost-effective visibility into system state and proactive issue identification without additional financial burden.
• Redesigned BNPL authentication flow by introducing a dedicated, highly configurable microservice, achieving significant performance improvements and reducing latency from 200ms to 10ms.
• Redesigned token handling by incorporating a new design to include basic user details for better microservice efficiency. Implemented Redis caching in the API Gateway to convert opaque client tokens into JWT tokens, boosting performance and security.
• Engineered a scalable and configurable Device Store system to combat fraud in BNPL transactions, achieving throughput of up to 35,000 requests per minute (RPM) with average response times under 30 milliseconds.
• Configured ZGC to the existing Java services increasing performance by 20%.
• Led critical project integrating OpenTelemetry (OTel) for monitoring and logging, significantly reducing integration costs by surpassing reliance on paid tools.
• Implemented development best practices such as thorough unit testing and robust exception handling throughout the project lifecycle.
• Proficiently utilized Kubernetes (K8s) to deploy and manage microservices at a high scale, ensuring seamless orchestration and efficient resource utilization.
• Developed a Jenkins pipeline to automate the identification and deletion of unused kong ingress resources by comparing repository-defined ingress configurations with those deployed in the cluster.
• Implemented Graviton-based EC2 instances, achieving a 15-20% cost reduction and saving approximately $60K in total expenditure.
