What I'm looking for

I seek senior architect roles focused on GenAI, cloud-native data platforms, and scalable API/microservices delivery, with opportunities for technical leadership and operational excellence.

I am a hands-on solution architect with 25+ years designing and delivering large-scale, secure platforms across financial services and enterprise domains, with deep expertise in GenAI/RAG, Java and Python microservices, Azure, OpenShift, Snowflake and high-throughput OLTP systems.

I have led GenAI programs, data platform modernizations, API and microservices architectures, and large operational deployments—delivering measurable platform readiness, scalability, and operational observability while standardizing engineering patterns from POC to production.
