Developing one of South Africa's leading online Debt Collection Software. We serve clients in the retail, banking, and collections industries.

We do Test-driven development and all code is reviewed by at least one other team member before it's merged into master. My primary role is Developer, but I've also been involved in setting up web and database server infrastructure, configuring MySQL replication, recovering databases from binary logs, setting up CI/CD and merging databases.

I assist where I'm needed. Anything from interviewing candidates to arranging for a new coffee machine and fixing the magnetic lock on the office door. I'm currently also part of a technical committee which is responsible for technical design decisions.

Projects: Branch Locators, Weather & Traffic

Developing a real-time vehicle tracking/fleet management system using PHP, Javascript, Java and MySQL ons a custom Javascript-based web framework.

I worked in R&D and built POCs for a Document Tracking system, J2ME-based tracking application and processing spacial-data files.

Building a new in-house Web 2.0 framework in PHP.

Projects: Document Tracking, GPS-Tracking Solutions

Swordfish is a web-based debt-collection system developed using PHP, MySQL, Javascript, HTML, CSS, PropelORM and Memcached. The system allows users to manage Debtors and keep track of communication (SMS, AVM, Email, Phone, Letters etc.) as well as manage, track and report on the Debtor's Accounts. I was responsible for several third-party integrations including SMS, AVM and Debit Order/Payment services. Provider APIs included REST, SOAP, CSV and Fixed-width files.

A new version of Swordfish was developed, with Python, Django, Django REST Framework, PostgreSQL to provide a REST API to a frontend built on HTML5, Bootstrap4, SASS and knockout.js.

I've designed and developed the core parts of our in-house microservices framework. The framework provides a REST API to various third-party integrations and is built using Django REST Framework and PostgreSQL. Asynchronous task processing is taken care of with RabbitMQ and Redis. I continue to support team members with new integrations, ensuring that code is of a high standard.

Bridge Loans/Loan Buddy - A loan-origination site developed using CakePHP 2.x, jQuery, SOAP, REST, JSON, HTML, CSS which integrated with the company's SQL Server database and other internal systems.

Bridge Recruit - a PHP-based social recruitment site used by Bridge which integrated with a third-party recruitment website's API.

I developed various ATM and branch locators on different platforms including USSD, mobi and web. USSD branch locators were developed in Java using an in-house framework. Mobi- and websites were built with CakePHP. All solutions used MySQL as a database and integrated with a Location-based Services (LBS) API provided by one of our mobile network partners.

These two projects were both written in JSP and made use of MySQL database. We processed partner-provided data which we received in XML format on an FTP site at regular intervals. This provided the back-end to mobi- and website subscription services.

This proof of concept was built in PHP and made use of Passive RF tags to track documents throughout a building. RF tags placed in folders or on documents would be recorded to a database as they passed by RF scanners located throughout a building. The data was then mapped onto a blue-print to indicate the whereabouts of the documents.

A real-time vehicle tracking/fleet management system which enables clients to track their vehicles or fleets using GPS/GSM tracking units. The system also provided users to specify rules (e.g. times; geo-fences) in which vehicles are allowed to travel, and can trigger SMS or Email alerts should a vehicle violate these rules. The system also keeps track of all vehicular activity that can be viewed at any time.

The web-based interface developed in HTML, CSS, Javascript and a PHP backend with a MySQL database was supplied with the data from GPS/GSM tracking units to a socket listener written in Java.

Featured in Innovate Magazine (Issue 3 of 2009) for Signum, a Java-based hand-gesture recognition system that allows control of a media player on you computer. I was part of a group who developed this for Prof. Andries Engelbrecht in 2007 as part of our third-year Software Engineering course.
