Nedbank (Client of Comvision)
  • Wrote three modules for the collection system at Peoples Bank: a module to manage third-party external trace companies, a module to manage third-party attorneys, and a module to manage the handling of write-offs for the bank. All the modules were built on the Flux framework, which I developed for Comvision.
  • Hired to give guidance to the MIS department at Peoples Bank. After automating the manual procedures in place and developing structures to generate and distribute reports throughout the organization, I negotiated a deal whereby Comvision supplied and managed resources to develop software for Peoples Bank.
  • Oversaw the development and implementation of a collections system and an up-front segmentation system. Both systems leverage the intranet for the user interface and utilized the RDMS SQL Server to protect the data and enforce business rules. Both systems have become mission critical and are an integral part in the success of Peoples Bank. The credit checking system is responsible for assessing and processing loan applications. It comprises an out-of-process component to asynchronously query the Experion database and a system of parameter tables to manage application scoring and ensure a dynamic environment essential to the business.
  • Created the debt collection system using a product called Flux, which is the property of Comvision and is a unique framework capable of developing complex workflow systems in a relatively short space of time. Flux excels at enforcing business rules for organizations whose business rules change frequently and sometimes dramatically.

Because of the difficulty in deciphering the handwriting of those in the medical profession, the actual documents were scanned into the system and stored on the database. We used a product called Image Basic to allow users to zoom into and out of the stored images in order to decipher the handwriting and keep track of all the notes scribbled in the margins.
  • Produced a series of stored procedures, which extracted the data and images for publication.
  • Created a series of GUI screens to maintain static data and data relationships.
  • Identified ways of speeding up the workflow system especially with regard to uploading large images. I eliminated unnecessary processing and significantly improved performance on both the front and back ends.

A D3 interactive visualization for answering questions from data-driven by mining vehicle telemetry. The application was used on open-cast mines and was part of a collection of features designed to optimize operations.

D3.js Developer

Several specially customized charts that I created with D3.js and to aid the client in settling on the correct config for each chart, I created a React app that allowed the client to try things out before committing to the settings and integrating them into their system.

D3.js Chart Portal

https://medify.scirebug.net/
A React-based app to assess D3.js charts before integrating into an Ember application. The point of the app was to enable the client to choose between the many config options available before integration. The D3 charts were designed to fit into the available container and adjust themselves accordingly.

Education
