Developed a responsive, mobile friendly site where debtors can view their accounts, make payment arrangements and contact debt collectors. The site was also updated to replace the old login page with a One-Time Password (OTP) based login. The site was built using PHP, MySQL, Bootstrap4, SASS, HTML, Javascript.

A responsive web interface for browsing folders and editing JSON-based configuration files. This project was built using Python, Flask, Bootstrap4 and delivered with bash scripts for installing the required dependencies which included nginx, WSGI, Gunicorn, Supervisor and a rsync script to sync with multiple Raspberry Pi devices.

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.
