I have over 30 years' experience serving as technical lead and architect in the development of award-winning core business solutions in leading financial organizations - mostly in COBOL and DB2 on the AS400 (aka iSeries or IBMi) platform. I can perform research and development assignments, from a short POC to a full project - online and/or batch, including CL programs, DDS, SQL, CMD, Query, QMQRY, DTAQ, DTAARA, Triggers... whatever you need to make your application solid and performant for years to come. I can develop on your machine or mine. I can perform analysis and design/code reviews, provide solutions for performance and database issues, and help you implement advanced techniques such as session/global variables or memory caching. I have trained and mentored over 100 people over the years, in public classes at IBM and internally in large organizations. I am a US-born citizen, and speak fluent English.
