Project history
Designed high-throughput async processing API with dynamic rule-based validation engine for global user/role management. Directed technical design, code reviews, and implementation for core identity entities. Automated deployment workflows by establishing end-to-end CI/CD pipelines in Azure DevOps.
Developed asynchronous bond trading platform integrated with Solace message queues. Conducted deep-dive performance tuning to reduce system latency and resolved critical production bottlenecks. Prototyped rule engine integrations for complex trade validation.
Developed reactive, containerized microservices for AWS Kubernetes. Engineered client-level encryption for DynamoDB and implemented consistent event propagation using DynamoDB Streams.
