I have over two decades of experience designing, implementing, and maintaining applications that meet large, complex customer needs. I have taken many critical applications from pure vaporware to working. Much of my code runs in production for large financial institutions serving their most complex corporate clients.
I am always interested in positions that provide a significant new challenge over what I have done in the past.
Recent projects include:
• I reviewed/audited a large Java codebase that had come to the client through merger and acquisition to confirm that the code was complete and had, in fact, all been delivered to them from the seller.
• Designed and implemented REST APIs and other backend components deployed in Amazon AWS. These APIs process large volumes of payments for business and individual customers.
Technologies used in this job include:
• Java
• Spring Boot
• MySQL
• ActiveMQ
• Docker
• Amazon AWS (ECS, EC2, RDS)
• Linux
