Developed new features for an existing loyalty platform, supporting both grocery and convenience stores. On the back end, I worked with Struts and Spring, using DB/2 for database management, while enhancing front-end functionality with AngularJS.One of the new features, above, required I revisit my compiler/parser background to build a LALR(1) parser for a small expression language used in the feature editor. This was done in Java REGEX for lexical analysis, with a hand-coded syntax analyzer.Another feature translated XML messages in and out of an existing point-of-sale back end, making that communication stream available in a more standardized dialect for a different point-of-sale. This translation used Orika to perform deep mapping from one dialect to the other and back, submitting translated requests to the original back end, and translated responses back to the requester upon return.Created tablet app that used the iPad camera to read UPC/GTIN and PDF417 barcodes at the point-of-sale, to scan loyalty cards and drivers licenses. This communicated with the back end over an existing communications channel to register new cards, issue rewards, redeem rewards, and view balances. This replaced aging VX570 devices, which were no longer supportable.Developed iOS and Android applications for client retailers and built a progressive web app (PWA) in Angular 2+ for tobacco retailers. Additionally, created and maintained a Spring-based REST service, which provided support for the above mobile apps, the PWA, and third-party developers.

Led development across multiple startup clients, creating complex websites in Python and DB/2.Directed the development road map to best meet company goalsOn one project, the client brought me a nightly SQLServer batch process that was approaching a 24-hour runtime, hoping to get it down to under 6 hours (for morning availability). I re-implemented this code (staying within SQL Server), bringing that process to sub-second response time. No batch process neededDeveloped web tool for the visualization of 3d cluster maps on an html element

Part of a small team that acquired the IP from FuelLinks and rewrote the system in Java. Expanded the platform to include an 8583 credit-network interface.Enhanced system scalability and performance.

Helped refactor a monolithic loyalty system, reducing code base from 40K lines of C to a more reliable and maintainable structure with shared source code.Developed interfaces for various point-of-sale devices.

Member of a team of programmers developing tools for banks (I mostly worked on GUI, rather than banking). Later Work included developing ActiveX controls for use in Visual Basic and Visual C++ forms used by the app development teams in the larger company I found myself in after the acquisition by FiServ.

Developed software to assist in converting "C" source code from Windows to OS/2.Evolved the project into an annotated source tree conversion tool using BNF grammars to handle arbitrary languages, including "C", Pascal, and C++. Gained expertise in compiler theory.

Created a comprehensive UI front-end for an existing host-based claims processing system.Reduced training times for claims processors and decreased per-claim processing costs.Developed using EASEL with back-end support in "C" using EHLLAPI and APPC for communication between OS/2 desktop clients and mainframe hosts.

Served as a consultant at American Airlines Sabre division, writing documentation and developing "C"-based tools for internal use in two different departments.Created a printing module for car and hotel rental vouchers used at airport ticketing terminals.

Spent a week or two at a time with various IBM customers, training them on OS/2 development, and helping them debug problems, launching their new OS/2 projects or porting existing projects from Windows.Sometimes the client team would all come to Southlake for training, sometimes I would work onsite with them, especially if there was an installation that required debugging.One site visit included a VA hospital, helping debug an issue on a prescription-filling automata that included conveyor belts, pill counting hardware, label printers and more. Very cool to see software control things in the physical world.The system would consistently run for 5 to 6 hours and crash. I looked through their code, and watched the system run for a day or two, then made a suggestion about how to go about memory management. They initially balked at the suggestion. I was notified weeks later that they were now happy with the suggestion, because the eventually gave up and followed my advice.
