Engineering Leader | Distributed Systems Architect | Ex-Walmart, Rakuten, Oracle | Cloud SaaS Microservices Observability RAD Platforms

About

Engineering Leader and Architect specializing in the design and delivery of high-reliability, fault-tolerant distributed systems and Cloud SaaS platforms at massive scale. Throughout my career at Walmart, Oracle, FICO and Rakuten I have focused on building foundational infrastructure, microservices, RAD platforms (such as FAWB at FICO) and observability engines (such as Rakuten’s SixthSense) that maintain 99.99% uptime, rather than standard application development.
