What I'm looking for

I’m looking to lead QA automation and EDA testing for low-latency, regulated platforms—building reusable C#/.NET and Python frameworks, enforcing shift-left quality gates, and partnering on performance baselining and automated compliance auditing.

I’m an experienced Senior Lead QA Automation & EDA Engineer with over nine years specializing in low-latency trading architectures, Event-Driven Architecture (EDA), and data reconciliation in heavily regulated financial markets. I architect pipeline-integrated, reusable .NET automation frameworks using C# and Python, with deep expertise validating complex message semantics across Solace, Kafka, and RabbitMQ.

I build containerized, deterministic testing architectures on Azure Kubernetes Service (AKS), while implementing shift-left strategies, performance baselining, and automated compliance auditing. In practice, I validate ordering and idempotency semantics, enforce DLQ handling, orchestrate integration and resiliency coverage, and apply contract testing with Pact to prevent breaking changes during promotions.
