12/2012 – 11/2015 Indaba Mobile
Indaba's business model revolved around a white labelled, multi tenanted mobile chat
application consisting of a client (mobile device) and a backend stack (concurrent,
distributed, scalable microservices hosted on linux based amazon web services).
My responsibilities were originally the architecture and development of version 7's relational
data (mysql), the interface thereof (php, react.js, node.js (only as tooling env), webpack), the
exporting of data from a relational structure to a distributed database (cassandra) and
debugging on multiple concurrent (distributed) nodes on AWS for both virtual machine and
RDS instances.
Other responsibilities included aggregating, debugging/maintenance, and client facing
interface for survey data, resolving/profiling stack issues(load balancers, activemq
messaging, akka message queues, internal traffic analysis, tomcat), maintenance of legacy
software and identification(wurfl) and distribution of client applications.
Later this was expanded to include java development with spring, hibernate, camel, jersey,
mina and drools.
Technologies used being zend 2, react.js, jquery, jquery-ui, spring, tomcat, activemq, apache,
mysql and cassandra.
As a company, it was going insolvent, which is why I left.

01/2012 – 01/2013 Zapop
Although billed as a digital media company, Zapop developed prototype systems.
By far my most exciting project was an autonomous robot. The robot would take panoramic
images every few meters, pass the image through object recognition software and catalogue
the results. My part came in with the user web interface which took the panoramic image
and created a 3d environment whereby the user could browse the catalogued objects and get
visual information of the state as when the panoramic image was taken.
Other projects included a touch-screen notifications panel for varying devices displaying
alerts according to sensor data (temperature, database irregularities, no power, etc), and an
e-learning/learning-management-system platform based on moodle.
Technologies used being Cakephp 1.3, MoSync, jquery, bash, html5, REST, GIT, Redmine.
Unfortunately transport became an issue (2 hours by car, 5 hours by public transport) and it
was with regret that i left the company.
09/2011 - 01/2012 Freelance
The aim was to get my own mobile development project off of the ground while doing small
local projects and online freelance projects.
My mobile project consisted of an android application encompassing public transit times
and up-to-date notifications fed via a REST server built on zend framework. The Android
client was written in Java using the Android libraries.
The project was abandoned since the freelance work was not keeping me afloat.
11/2008 - 09/2011 Finassets
Finassets, a subsidiary of TrinityAssetManagement, is a financial portfolio management
company.
Responsibilities here consisted of
setting up development environment (subversioning, bug ticketing system/tracking, wicki
documentation and development/testing/failover server management),
project management (scrum),
and finally software development process (requirements specifications documents, writing
code, subversioning, debugging/stress testing, etc).
I was retrenched due the portfolio component of the company coming into trouble.
07/2007 - 11/2008 ViaMedia
Viamedia (WASP), a structured, technical environment, catering towards mobiles devices.
Here I built in-house web interfaces for data loading, C++ application interfacing, and WAP
portals via a rigid software development cycle ... requirements specifications documents,
writing code, subversioning, debugging/stress testing, packaging(rpm/make), and finally
documentation/release notes.
10/2005 - 07/2007 LiquidLimeStudios
A close, personal, web development company. LiquidLimeStudios focused on small to
medium websites.
Started out by creating a more client friendly/orientated cms for small to medium websites,
employing traditional php/html templating. With the advent of Adobe (LiquidLimes
flagship project) a more complex structure was used, requiring XML/XSL templating.
The project itself involved students submitting digital media, whereupon a judging panel
would asses and rate these submissions. The site had some challenging requirements, such
as support for 8 languages (managed content), differing media formats, and heavy loads.
Left since I needed to expand on my career.
10/1999 - 10/2005 Cybersmart (isp)
Joined Cybersmart when the company just started (1999), building physical part of the
network (copper cabling). Since Cybersmart was still small, i was taken into other parts of
the ISP, from dialup/desktop support (servers, routers), administration, to web development.
The company was pursuing primarily administration and my direction was moving towards
development, so left to pursue development.
10/1995 - 10/1999 Electrepairs (building and industrial maintenance
Completed as a qualified Industrial Electrician
01/1995 - 10/1995 All Security (Alarm Installations)
Installation of alarm systems, intercom systems, and access control
12/1993 - 01/1995 Macs sports bar (barman)
Development Experience
Javascript
Working with javascript almost as long as with HTML (1999/2000) so i've been around the
block of javascript frameworks with mootools, moving over to jquery for a couple years,
jumping between backbone, angular and now (primarily) react/redux/jsx in both prototypal
object oriented and functional patterns (primarily ES6) influenced by clojurescript
(idiomatic, stateless/immutable, agile REPL development).
Projects range from spatial google map interfaces, 3d interfaces (panolens), eCommerce (on
Hybris/Spring, oAuth JWT’s), broker portfolio management, mobile chat applications (both
websocketted, peer to peer and via server api’s) incl content management, administration
consoles and graphs/reporting.
Predominant libraries being React, Redux, Bootstrap (with Sass) for building service
oriented (incl websockets), SPA’s and multi page, responsive applications which run on a
range of platforms.
Development, packaging, integration and deployment tools via Eslint, Jest, Webpack, Node,
Sonar, GIT, Jenkins, AWS/Buildkite, ZSH, and Bash.
Primary editor being vim with linting via eslint and REPL integration via tmux/slime.
Clojure
It took me a while to shake off the imperative world, and learn to change perspective to an
immutable state. Though this is still a very new language to me, it’s fast become my
favourite with the whole idea of REPL development, it’s a lisp, idiomatic, functional … all
the awesomeness packed into one language!!!
My flow jumps between a terminal emacs environment married with tmux and a headed
REPL relying on evil-lispy, eastwood, helm, projectile, magit, … to one of VIM based off of
fireplace, vim-slime and sexp.
ClojureScript
Much the same as Clojures’ story except my flow works around a figwheel repl and react
(reagent/rum).
Java
Spring being the predominant framework in conjunction with hybernate/jpa.
Tools have been primarily handled via a hybrid of eclipse and vim (eclim) using maven and
ant, code quality via Sonar, deployment via Jenkins/Docker.
Experience is built up between ecommerce (Hybris, Spring/Solr/Hibernate) and custom
microservice architectures based off of Akka, hosted on AWS.
Source being managed by svn and git via both bitbucket and cli.
PHP
This was my primary language since 2005, due a large support base. Predominant servers
being linux/BSD based on both apache and nginx.
Frameworks I'm most experienced with being Zend2 followed by CakePHP and Yii.
Commonly employed patterns being MVC integrating ORM, Factory, Singleton, etc.
Currently exploring Symfony and Laravel.
Tools range from Compojure, the linux CLI (Bash/Zsh), xDebug, kCacheGrind, jMeter,
PHPUnit and Sonar for code quality.
VIM being preferred editor/project manager on top of Docker.
MySQL
I'm well versed in the design/architecture, backup, replication and of course general
querying.
Tools used being the cli, workbench and sqldeveloper.
Cassandra
Very basic work, exporting/restructuring from relational data to distributed data.
Tools used being the cli, kdm and cql data modeler.
Datomic
Building of basic queries off of existing data structures within restful api’s.
Tools used being a clojure repl.
Postgresql
Designed user authentication/authorization scheme’s and content management in much the
same way as I do mysql without any major hiccups.
Tools used being the cli, pgadmin, sqldeveloper and mysql workbench.
GraphQL
Only worked with it in a purely experimental/personal capacity.
HTML/CSS
Been using html/css since 2001, xhtml-strict since 2007. Using a range of tools supplied by
firefox for validity checks, useragent switching and of course profiling with firebug. Styles
predominently from bootstrap and on personal projects, jquery-ui.
Pre-processing being SASS via LESS parser.
Tooling used primarily derived from node.js being a webpack build environment auto
bundling via less/scss parsers.
Either Eclipse or VIM being the two major editors used.
XML/XSL/XHTML/WAP/SOAP
I've used SimpleXML, DOMDocument, Javas' SAX parser back in the day and javascripts'
native libraries for parsing rss, atom, soap, configurations and html.
Structured usage of XML ranging from XHTML, WAP/WML, SOAP and XSL/XSLT
transforms with DOM navigation/searching with either 3rd party libraries or xpath querying,
including namespace definitions/dtd's.
Image Editing/Design
Image editing/SVG/engineering drawing/3d sculpting skills with Blender, Inkscape and
Gimp.
Bash
Writing an assortment of admin tasks ranging from database implementations, application
deployment (CI), restful api testing suites (curl), scheduled crontab data ftp'ing, text
processing and debug/profiling tools, radio station streaming (for the love of cricket), cli
bitcoin tickers, cli cricket score tickers, cli tv remote, rc api for arduino based robotics (toys
tbh).
Perl
Web applications development between 2000 and 2005 before moving over to PHP.
Python
Adjustments to existing code, extending libraries … ad hoc where required.
SQLite
A few personal projects linked with Google Maps, Android and Java.
C++
In the passed i've worked with C++ on the MoSync framework to develop mobile
applications for multiple devices though this skill is once more dormant.
Very basic (more C than C++) work with the MySQL++ library for internet café billing
systems using Vcc and GNU’s Gcc back in 2004.
Arduino C
Prototyping of CNC (grbl and RAMPS) 3d printer/laser engraver, hydroponics automation,
GPS tracking with spatial services integration.
Utilizing ioc (incl Amazons Alexa), bluetooth, and RC integration shields.
