Humm Group white labels credit cards and provides financial services such as small to medium-enterprise equipment leas-ing. Specifically, Humm provides consumer credit cards / Store cards such as the Farmers 27 chain in New Zealand and the QANTAS Pay card.
Since I have had experience with financial services and credit card processing online in one form or another since work-ing with Plink libraries at BDE in 1997; I was able to quickly adapt to the workflows, codebases/business practices of the credit card services provided by Humm Group to provide bug fixes and minor maintenance on 192342 lines of Swift, 879 lines of Objective C, 334037 lines of Kotlin, 47,982 lines of java, excluding libraries. To develop the changes to these codebases I reviewed Figma diagrams and incorporated changes to UI elements in Android and iOS code as per the requirements of the JIRA tickets.
To modernise the build environment, I added Azure DevOps / Fastlane CI/CD build pipelines for a few of the apps.

Watch App
Added f eature of Braintree payments integration in Swift and Kotlin in an app for NSW Government including
Apple Pay and Google Pay.
The previous payment integration had reportedly been problematic and the payment gateway vendor for Braintree was almost effortless.
It took less effort and resources than expected so I added the features of Apple Watch and Android Gear Watch integration into the app for the NSW government.
Did a custom notification where the countdown timer and buttons appear in the phone notifications even on the lock screen.
The app communicates with an internal server, which acts as a proxy for another server that manages parking meters.
Part of the credit card processing integration occurred on the parking meter servers and part was within the app.
The idea of the app is to pay for parking meters from the phone and be notified of the need to top up the parking meter if it is about to expire by tapping on the watch and the phone notifications.
Complex integration due to the number of servers involved and the number of moving parts and the level of security.
All the watch app extensions, all the app to payment gateway integration.

iOS and Android developer.
Technologies: Swift / Kotlin
Maintenance work and small projects involving C#, Swift, Java, and Kotlin (Mostly Java on the Android side of things).
Fixed about a dozen bugs each week on Android then about a dozen on iOS the next week. The code was breathtakingly bad, if the server found no results in the database it would return 404 instead of 200 and an indication of an empty dataset in the JSON payload.
The server would 500 or 400 frequently on requests that worked a minute ago. · Payments
Somehow previous developers had considered the foreground and background of the app to be handled in view controllers instead of the app delegate, there was a lot of surreal code.
Whoever wrote it had no idea of the application life cycle or standard industry practices like not abusing HTTP error codes.
I was doing work on iOS, Android and ASP.NET and completing features in two weeks they had waited 2 years to be completed.

Client: eDale / ServCorp (Contracts)
Technologies: Swift / Kotlin / Objective-C / Java / Node.js / Heroku / PHP / Larvel / CodeIgniter / L A TEX/ Android
Comments: Several overlapping short-term contracts. Some clean-up of previous work for Edale, bug fixing, and random ad hoc changes. Hand over and manage a developer I hired through my own company to take over work.
Short-term work on Bluetooth tile beacons for finding car keys - type tag beacons. Another USB-based Bluetooth beacon
(Sensoro) and QR code project for allocating desktop handset phones and Wifi access. Worked 3 days a week at Servcorp doing maintenance work on an iOS and Android app that allows for provisioning of desktop handsets and (guest) wifi access
Sensoro beacons, translating Chinese comments into English. Implemented feature of Android circular reveal animation like the iOS animation. completed button handlers, differentiated between my wifi and guest wifi buttons and called different web service endpoints accordingly. Scale and slide up login animation to match the iOS version. Made UI consistent with the iOS version. Added disconnect handset screen in Kotlin.
Added feature of pull to refresh the menu on the Android version to be consistent with the iOS version.
Added site features refresh endpoint call and UI update. Added background handset polling. Used to be location dependent. Fixed refresh, device count wrong and other bugs in. both iOS and Android versions.
A branch was created in the source code control system called allow_handset_choice to allow the choice of a beacon/handset other than the nearest found beacon. An extra button was added to the found handset screen. Touching this button launches another screen with a list of handsets detected. On both the iOS and Android versions all the beacons that were available in the area are stored in collections in the bowels of the Bluetooth code. In both versions, the collections were propagated up through the software layers until they Servcorp are presented in a UITableView or a recycler view and the on-item selection handlers then put the selected OneAp
MAC address in place of the nearest found beacon MAC address and then call the occupy handset code which calls the web service endpoint (Function 16).
Half of the endpoints of the ServCorp server were in CodeIgniter and half were in Larvel in another repository. I set up a local copy of the code bases on my development machine for debugging server-side and client-side issues.

The COGS talks (via SII replaced by Tuxedo) to the Boris server which contains Pro*C code to talk to the Oracle (7.3.4 replaced by 9.2) RDBMS. The SII section I was responsible for was the SIDL which is like the CORBA
44 IDL and is kept in a repository which is like the Windows registry. I wrote code to load SIDL to emulate the repository.
The original target platform was HP and later moved to AIX. I did a partial port to Linux to do work on my laptop.
Testing of the interface to another system that communicates via ORACLE database pipes. Took a reworked C# client that communicated via OpenUI to the SII Boris and got it to call the Tuxedo Boris from the last two contracts. Led a team of three developers. Training developers, administration, project planning, architecting solution, etc, etc.
SNMP Support for the previous application. Wrote a server that polls a shared memory segment and dumps content to a log file to be retrieved by CA Unicenter Log Agent 3.0 and sent to the SNMP port. Also wrote a debug test harness that forces exceptions to be thrown for the “catch and send SNMP trap” code. Prototype for EJB interface for the previous application. Configuration of a WebLogic8.1 and Tuxedo8.1 server on Windows XP. WebLogic to Tuxedo (WTC) code. Java server pages to call the EJB. Ant scripts in XML to compile and deploy the EJB in the WLS. A C++ test program to call the test target service in “BORIS” as a prototype for the JSP/EJB prototype. WebLogic and Tuxedo domain configuration, on Linux, Windows XP and AIX. Documentation and support for previous projects. Maintenance work on the C++ and OpenUI OPL source code on the Macintosh client. Wrote C++ Tuxedo test harness for SIBEL interface.

progress updates. One of the bugs in the systems was a multithreaded construction/destruction bug which was re-lated to multiple inheritance and the C++ diamond problem as can be inferred from the following code snippet and opposing
UML diagrams:-
class Y: public X {}; instead of class Y: virtual public X { }; and class Z: public YA, YB {};
Once the bug list was reduced, I migrated the code from the Or-bix, ORB to the ACEs TAO ORB because the company wanted to X use more open-source software and not pay for commercial licenses. I reran the unit tests for all relevant parts of the system and worked

Comments: Train scheduling. I produced graphical reports in MFC/C++, (eg zig-zag graphs that show when trains are scheduled to arrive/depart at points up and down the line). The environment was ORACLE Pro*C which was wrapped within smart pointers which loaded an internal cache, pre-fetching and lazy-evaluating as required. The development environment was initially extremely chaotic which I resolved to structure. I introduced, set up and maintained, QVCS as no source code control system was used and QVCS (a free/cheap product) was used at SMA where I was working concurrently (together from 6:30 am to 9 pm every day and sleeping through the weekends).

C++/3D Game Engine Programmer for Defence Project.
Comments: This was originally a 6-month contract which was extended to 11 months to coincide with the completion of the project. This was an extremely challenging project which required examining a real piece of equipment (EOSS) a system much like a periscope on a submarine and developing a design to simulate it. A director head with DLTV and Thermal imager sits about three-quarters the way up the mast of the Huon class mine hunters. On the bridge of the ship is a console that was simulated. I had to put 3 video cards into one computer and get all the device drivers to work together. Then I had to get hardware-accelerated Direct-3D to function on two video cards, and load textures and vertexes into each card, while the other video card displayed a menu system, I wrote that mimicked the controls on the real bridge. Some video cards would detect that they were not the primary display device and switch to software rendering. Other video cards would steal vertex lists or not load textures. The thermal imager had “White hot” and “Black Hot” modes and therefore two sets of textures had to be loaded for each object and flipped between them in the scene as the controls were accessed. The daylight TV camera had an intensity control on the touch-sensitive control panel and therefore I had to walk the vertex list on the video card and adjust the lighting intensity of each vertex in the scene. The glow and dim effect was quite spectacular and was quite cool to play with. Additional functionality included socket code to interact with an Instructors station (which someone else wrote). There was also a Digi I/O board added to the machine which enabled digital/analogue conversion of signals. The project was completed 2 two weeks ahead of schedule and I spent some time profiling and optimising it as much as possible.
The Navy was happy to sign off on the project.
I tendered a project to replace the MADS (disk packs) on the submarine project. The small tender (roughly $100,000) was successful but the project ($100 million plus) was suspended indefinitely (pending a Royal Commission). If the tender was not revoked I would have had additional continuing contracts with SMA.
This was about the same time that I had the BeOS C++ Ray Tracer article published in Doctor Dobbs Journal. 52

Device driver developer.
Comments: TowerTechnology develops document and image processing systems and workflow solutions. I was responsi-ble for maintaining the device driver code for the medium changers (large mag-optical disk libraries which contain crypts for disks and several drives). I became an expert on the SCSI bus protocol. I wrote a class factory pattern-based diagnostic tool. The class factory would generate objects of all medium changers that the company supported and dump all kinds of diagnostic information.
I completed a device driver for Sun Solaris to access the medium changers via a pass-through SCSI device driver, debugged multithreaded kernel panics on the Tru64 platform and debugged faults on the HP-UX, AIX, Solaris, Tru64, and Windows
NT drivers.
One of the faults included reworking some of the drivers when the disk capacity increased from 2.6Gb to 5Gb, 32-bit limits were exceeded and block orientated seeks had to be replaced with ioctl()s on the devices. Some faults required some functionality to be moved from the upper layer of the kernel to the lower-level drivers or vice versa

Comments: The product "Digital Fusion" was an Object Oriented, multi-processor optimised, multi-threaded spline-based, resolution-independent video compositing system. My role was to design and implement features file format loaders and savers for the majority of graphic file formats (two dozen variants like JPEG, Sun Raster, PNG, TIFF, Gif, etc). I wrote
Windows Registry code and various graphic processing code including Sobel and La Placian, edge detection, and blur filters.
I wrote MFC/GUI code for custom controls like a “rubbery” range control (like 2 slider controls in the same control, which stretched and contracted at limits), screw control with infinite wrap-around looping behaviour. The entire GUI was based

on ray-traced images and was extremely slick. Amiga style “intuition layer” framework so that existing components would benefit from underlying extensions. DLLs could be dropped in so that at load time the system would recognise and register new components. Aspect-orientated/delegate style development. System administration of Lotus Notes, Novell Netware, network, and CISCO router. Build a system with Install Shield.
For some months all of the staff went to meetings with angel investors, and business partners overseas and attend SIGGRAPH conferences. I was left alone in charge of the company, answering phones, making sales, sourcing suppliers, deciding markups, arranging conferences, transferring money, paying bills, and my wages.
