Background

Summary

30 years of experience in the software industry covering a broad range of roles in leading edge architecture, and spend much of my time of late working with IT leaders to define and execute on new strategies for building and integrating critical applications that scale reliably and predictably.

As an engineering leader and architect, have lead many successful innovative product efforts, building highly effective teams and delivering quality products under extreme time-to-market conditions.

As a performance and scalability lead engineer, have helped several financial institutions exceed their goals of high throughput and low latency applications.

As author of several books including the O’Reilly Enterprise Service Bus book, have had tremendous impact on defining how the IT industry builds service infrastructure and integrates applications together. Was a primary driver on the creation and evolution of the Enterprise Service Bus (ESB) technology category.

Author of several books, including “Enterprise Service Bus” (Oreilly), “Service Oriented Infrastructure:On Premise and In the Cloud” (Prentice-Hall), “SOA Design Patterns” (Prentice-Hall), “Java Message Service” (Oreilly), “Java Web Services” (Oreilly), and “Professional ebXML Foundations” (Wrox).

Specialties: Performance and Scalability, Enterprise Integration and message oriented middleware (MOM), Grid computing, Service Oriented Architecture (SOA), Enterprise Service Bus (ESB), Business Process Management (BPM), Event Driven Architecture (EDA), Complex Event Processing (CEP). As a public speaker, have delivered 100s of lectures at over 60 cities worldwide. Well known worldwide for my writings, and have co-authored many advanced Web Services standards.
