About Me

I am an experienced Technical Architect and Author currently living and working in Singapore, passionate about technology, always seeking to leverage new skills, products and features. Employed within the financial sector, I consult on enterprise wide infrastructure solution and design, particularly in Oracle technology, cloud orchestration and data replication.

As a subject matter expert I am focused on IT service management and strategy. Leveraging open source technologies, vendor products and cloud based services to deliver cost-effective, automated solutions to the business.

Since my first book the Oracle GoldenGate 11g Implementer's Guide, I have actively used GoldenGate to address real-world data migration and delivery issues. Known for my proven ability to provide robust, effective solutions and workarounds, I continue to share my knowledge, tips and tricks in my new book the Oracle GoldenGate 12c Implementer's guide.
