Recruited back to Zave to lead the software development efforts. Led a team of 10 engineers in the design and implementation of the next generation platform, including an in-store Point-of-Sale (POS) Controller with open API, an embedded terminal adaptor in the IBM POS, and a distributed platform architecture based upon collaborating RESTful subsystems (Multithreaded Java, Sockets, RMI, Spring, Ruby, Sinatra, Rails, MySql).

LogicLeaf is a boutique consultancy focusing on soft real-time, highvolume software systems built with Erlang/OTP and open source software.

A Techstars 2009 company, Spry made Spryplanner, a real-time dashboard for software development. By monitoring all the tools and services used to develop software and analyzing the data in real-time, Spry enabled clear and consistent communication throughout the team.An Erlang/OTP clustered web service provided real-time provisioning of asynchronous data monitors. The system had CouchDB as data store with Ruby on Rails as the front end.

Designed and built the first intelligent incentive platform linking online and mobile placement with in-store redemption, including a point of sale interface. Hired and led a team of 7 engineers. Directed the execution of 45 two-week agile projects. (Ruby, Rails, Java, MySql).

Hired and led a team of senior software engineers to build a distributed SOA framework for video processing. Directed the execution of Extreme Programming practices, completing over 40 two-week projects, each resulting in tested, production-quality releases. Selected all tools and frameworks. Customers were external developers who used the product to video-enable their applications. Key features included video encoding to multiple formats (“transcoding”), video capture, management and streaming. The 4-tier architecture exposed a Web Service interface and was implemented in multi-threaded Java and Ruby. It highly leveraged the Plugin and Service Locator patterns for flexibility. The internal asynchronous messaging protocol used UDP Multicast for auto-discovery and TCP for peer to peer communication. Hibernate was used for object persistence.

Architected and developed a 6-tier distributed media streaming system. The tiers employed out-of-band signaling to impose telecommunication standards on quality of service and billing, and allowed for complete session tracking. The network architecture and routing algorithms were patented. The system was implemented in multi-threaded Java, used CORBA and sockets for messaging, persisted objects with Oracle and Java Serialization, and ran on Linux, Tru64, and Windows servers. The presentation layer was implemented with Struts and JSP using Apache Tomcat. Analysis and design was done with the Unified Modeling Language (UML).

Designed, implemented and maintained many kinds of asynchronous network components and device drivers for Cerner’s healthcare software suite (C, VMS, RS-232, TCP/IP, LAT). Promoted to lead a new team in developing a client-server product to automate therapeutic treatment management (C++, SQL).
