Work on three person team creating the BigCommerce mobile application. I did both backend and mobile development.I did all the backend service development in Scala. I wrote a mobile specific micro-services that talk to other micro-services inside BigCommerce and provides specific services/data to the mobile applications.We started using React-Native but moved to using native mobile frameworks on iOS and Android as React-Native wasn’t fulfilling our needs. I worked on the Android application after completing the backend work we needed for version 1.0 of the application. The Android work was done using Kotlin, and consisted of updating the Java network layer to use Kotlin to talk to the backend services I had previously written. On iOS I helped with some of the Swift coding.Google Cloud, Scala, Android, iOS, Swift, Kotlin, REST API’s, Google Cloud DB, MySQL, Play framework, Akka, micro-services

Development on an application for Johns Hopkins Applied Physics Lab that apply's FFT’s & real-time data analysis and control of local and remote radio signal data streams on SDR equipped devices including but not limited to tablet computers, small devices such as Raspberry Pi's, and other highly mobile compute platforms. The application continuously analyzes the real-time radio data via custom FFT algorithms and plots that data in waterfall and waveform views. The users can change various settings custom FFT algorithms and of the radio via the UI. Those changes modify the running software as well as the configurations of the (SDR) equipment. The application can be run on one device or in client/server mode via GRPC, thus allowing the adjustments of parameters controlling the SDR equipment from afar.The app was written using JavaFX, Google GRPC, and Gluon JavaFX for mobile devices and Ubuntu Linux. The SDR equipment was small single board 4x5" and smaller USB connected devices. Including USB stick based SDR devices.

Working on a team that created Dell Financial Services – Online Services. Worked from inception through delivery as combination Development Lead/Tech Lead of two releases of DFSOS. Helped shape customer’s vision for what the site could be, to include work-queues, metrics, replacement of emails to customer with work-flows thru DFSOS, full integration of an online reporting system. The application was deployed and had only one bug reported against it in it’s first 3 months of use. It was also the only application that wasn’t backed out over Dell’s busy holiday season because of it’s stability. I was primary technical resource for the business on the team that picked the BRE for Dell Financial Services future growth. We choose Fair Isaac’s – Blaze Advisor. Additionally, I mentored customers and development team on use-cases, as well as doing all the site graphics work using Adobe Photoshop CS and conforming to Dell’s Internet/Intranet site design guidelines.We evaluated and prototyping using Ruby on Rails and Squeak/Seaside for features of the next version of DFSOS. We wanted to allow our customer to see some of our new ideas and get feedback sooner. We also tried to use this application as a lead in for more possible work in Ruby on Rails or Smalltalk instead of staying with Java for everything.DFSOS is built on top of the WebLogic Platform: WebLogic Server, Portal and Integration. We also used XML, XSLT, XQuery, web-services, SOAP, InfoLease Integration Manager, Struts, JavaScript, Portlets, JReports, POI, MS SQL Server, Oracle, Ruby, Ruby on Rails.

Wrote Java code for a highly distributed software installation and configuration system. The part of the system I worked on is responsible for doing the workflow processing of the BPEL and then calling remote web-services. I had handle these tasks in a transaction oriented way and I have to deal with error recovery, roll-backs, parallel processing, pause, resume and cancel situations, etc. My portion of the application required me to work daily with IBM Research.The system was built using the following technologies: Web Services, XML, XSD, Eclipse EMF, RDBMS, BPEL (Business Process Execution Language) and workflow.

Initially consulted on a intermittent basis starting in September 2001 and by November DynCorp decided to hire me for the remainder of the project bid period as a Liaison between BBN, DynCorp and Binary Group. I worked on a team preparing, presenting a bid to the DOD for the next generation USTRANSCOM GTN21 system for transportation logistics. This system is used to track all vehicles, airplanes, and other transportation entities for the entire DOD establishment. Anything in movement is tracked including people and cargo. It is like a FedEx but for transportation related data.Duties included: 1) Evaluation, design and implementation of all requirements for the databases (RDBMS and Data Warehouse) and business rules. 2) Evaluation and choosing of a J2EE compliant solution for data and rules architecture needs. 3) Use-Case, Class diagram and Sequence diagram development and coaching. 4) Helping review the entire architecture for completeness and coverage. 5) Make the data architecture and the data-warehouse architecture both suitable for easy to use with OLAP tools 6) Participation in the bid presentation to the U.S. Government Team of 20 people.Tools chosen included: J2EE, TopLink, Oracle 9i, Blaze Advisor Rules Engine, WebMethods B2B Gateway, WebLogic Application Server 5, JBuilder, UML and RUP.

Worked on the architecture team for a J2EE WebLogic 5 based product, doing database design and object to relational mapping using TopLink. Our initial version was on top of Oracle 8i with DB2 work just starting as I left.I also worked on the rules engine portion of the application, which was implemented using Blaze Advisor and Blaze Advisor Server. I helped to define how we would present the idea of rules organization and capture to our users and what features of the rules engine we would expose.I also worked on interfacing our product to the third party reporting tool, JReport. Left when there were budget cuts and a major shift in direction. Partnerware closed shop in July 2002.

Worked on Architecture team reporting to the Chief Architect of Capital One. Sold Java and J2EE to the architecture and development teams. I then worked as a senior architect/developer on a team of six on Capital One’s first Java and J2EE project; a next generation collections application. We used WebLogic 4.1/5. Modified RUP was used as our process. The end user-base for our application was 6,500+ collection agents. A large part of our application was an expert system (Blaze Advisor and Advisor Server) which allowed changes to complex business logic without having to modify the code base or stop the systems. I implemented the telephony portion of the application using Cisco's Integrated Call Management system and it’s Java interface. Calls from the intelligent dialers and the Cisco ICM and initiated the app servers linkage to a client desktop and the phone routing data/customer data transfer along with the call. Additionally, it allowed users to dial, answer, transfer and conference phone calls right from their computer while working with collections customers. I also worked on the expert system and rules for determining which accounts to collect on, agent routing, what method to employ for collection, as well as many other types of rules geared toward collection of moneys owed. After version one was completed, I worked on version two which included many UI improvements and expansion of rules and data sizes.Originally I was brought in to help solve performance and design problems associated with the C++ ORM implementation. The project processed all the VISA/MasterCard transactions that Capital One gets everyday (tens of millions). The real-time requirements of this huge processing intensive credit transaction system included performance needs in the line of 1 million update transactions an hour with concurrent queries in the range of 650 thousand an hour. The system was implemented on four, eight processor HP machines for the DB server and 8 Sun app servers.

Worked with OSG several times from 1993 thru 2001. I was one of the first three consultants hired to work on OSG's first project at PanCanadian Petroleum. I helped grow the consulting team there to 12 people. I also worked at Sprint and Capital One with OSG. I served as Head Mentor, Architect and Senior Developer on several different projects. I worked with the owner of OSG and went on sales calls, help create proposals, formulate solutions and other technical and technical sales type tasks. Other clients I helped OSG with include NASDAQ and Burlington Northern Railroad.Additionally, when I was co-owner of Interactive Web Systems Corp., OSG asked me to give a talk to Fannie Mae about the transition from NeXTStep to Java and J2EE (before J2EE was formally announced).

I was a founding partner in a startup firm that specialized in developing custom inter/intra-net solutions for a broad range of customers. Our company grew from 3 to 21 people in 1.5 years. We became a Microsoft Solutions Partner in its first 10 months of existence. This is almost unheard of. We specialized in Microsoft’s Internet tools and were the only MSP to specifically target those tools in the entire southwest region. We later helped Microsoft roll out version 1 of SiteServer and a product we developed was one of the demo applications they used at the Southwest region rollout in summer 1997. We also created many different solutions for Nortel including a Wireless Ground Station Configurator, a Project Resource and Costing estimator and others.I did sales presentations, presentations to user groups, worked on client projects doing design, development, and whatever needed to be done. I also set the direction for the company and enjoyed serving in that role.Alistair Cockburn profiled one of our projects (which was for Nortel) in his book “Surviving Object-Oriented Projects”.Clients included OSG, Fannie Mae, Burlington Northern Railroad, OSG, Northern Telecom, MCI and Ericson.

Worked as Architect/Mentor. Our team created a PBX configuration application for the Meridian line of PBX’s that Northern Telecom sold. This configuration tool did very complicated engineering, packaging, and EDI to the factory. (All driven by a rules/expert engine that I wrote. The rules engine was a forward chaining engine based on the Rete algorithm. The rules themselves could be any valid Smalltalk code), Example rules tasks included module placement, card placement, cable routing, software/hardware version compatibility, among others. In addition to the main tasks of the configuration tool, I created an installation system that worked over the Internet. I also interfaced Smalltalk to Electronic Book Corp.’s DynaText SGML browser. Design methodology taught was a grouping of Booch-93, Rhumbaugh, Jacobson and CRC. Technologies used: Visualworks-Smalltalk, SGML, C, Oracle, Rational Rose, Perl, Argos, Versant OODBMS.

Calgary, Ab, Ca

Worked as one of the three original architects of a major re-engineering effort involving NeXTStep in an MIS department (consultant team grew from three people to twelve and the involved MIS staff grew from six people to forty-five). Designed and implemented an infrastructure including a hierarchy of 100+ Common classes, a persistence layer for mapping objects and collections into relational databases, concurrency control approaches for application programmers, capture of business domain knowledge in the form of over fifty petroleum business classes, GUI design principles, standards (code, documentation, on-line help, and GUI), application deployment, testing strategies, design review policies, and other related functions.Worked as Lead Mentor in charge of all training. Devised a hybrid OOA/D methodology using aspects of CRC, Booch, Jacobson Use Cases and Rhumbaugh OMT, specifically geared for MIS individuals. Taught several multi-day courses on CRC, Booch ‘91 & ‘93 methodologies and the Model-View-Controller paradigm. Mentoring two projects of four people each in analysis, design and implementation using NeXTStep. All designs are captured using Rational Rose (OO CASE tool). Objective-C/NeXTStep.

I worked on this project as a second job at night while I was at PanCandian Petroleum.I developed an interpreter and debugger for a credit analysis language designed by American Express. The debugger had features such as step line, step function, watchpoints, and breakpoints. The solution ran on PCs under OS/2. The project plans called for American Express to develop the production version of the credit language to run on their IBM mainframe in COBOL. At the same time, I created the PC version in Smalltalk V/PM for OS/2 to allow programs to be developed and debugged before being deployed to the mainframe for production. I completed the PC version interpreter and debugger before the mainframe application was a third through development. Testing of the PC version showed that it ran faster than the estimates for the mainframe version, which led to the mainframe program development cancelation.I was asked to add a few features to allow for using the PC application as the production version. I added them, and then the PC version was deployed and used for final production for credit evaluations.As of 2005 I had heard it was still running, but it may now be offline as OS/2 support is a thing of the past.Used Booch ‘93 for design. OS/2, Smalltalk/V, PARTS.
