What I'm looking for

I’m looking for a Senior/Lead/Architect role where I can build Kafka-driven microservices, lead cloud modernization, and deliver high-availability fintech platforms with strong DevSecOps quality gates and agile technical leadership.

I’m a Senior Java Engineer and Solution Architect with 20+ years of production experience building high-availability, regulated fintech platforms using event-driven microservices. I’ve delivered 100M+ daily insights for 10M+ users and driven measurable outcomes like $600K+ annual cost savings through cloud migration and modernization.

I lead architecture and technical mentoring while integrating Big Data and streaming—Kafka, Flink, and Spark on AWS—to power real-time analytics and data lake flows. I also champion progressive engineering practices with GenAI-assisted development (Cursor IDE) and DevSecOps quality gating (SonarQube SAST/SCA) to keep delivery secure, compliant, and scalable.
