Faith
At the forefront of my life is my faith and my relationship with Jesus Christ. It is the lens through which I view — and take part in — the world around me.

Profile
About / the work
More than two decades immersed in IT — and Linux is where I shine brightest: beyond the binaries, into the operating system's innermost workings.
Operating environments
I've become a true connoisseur of operating environments — Linux, Solaris, AIX and the ever-present Microsoft systems. The expertise runs past surface level, deep into the core of each system, which is what lets me resolve issues and defy limitations with real efficiency.
Data & code
Databases are trusted allies: Redis, Oracle, Informix, PostgreSQL and MySQL, wielded with confidence to orchestrate integrations and extract the insights that drive decisions.
In code, I weave C, Java and PL/SQL together — and through Spring Boot I build microservices that work in harmony to unlock what modern applications can do.
Integration & people
I've lived through the great shift from XML to JSON — a transformation that rewrote the fabric of system integration — and mastered both paradigms along the way.
The craft isn't only technical: I bridge gaps between systems and stakeholders, untangling requirements into a common language and adapting to the perpetual winds of change.

Off Duty
Faith / road / farm / family
The Road
Northern Cape regional president of the Christian Motorcyclists Association (CMA). Motorcycles and faith combined — riding with people who share the same values, making a positive impact on others' lives.
Electronics
Tinkering is one of my greatest joys: exploring the inner workings of devices, experimenting with circuits, pushing at the boundaries of what they can do.
Farm Life
Home is a picturesque farm. Caring for the land and its animals connects me to the rhythms of the earth — and camping trips with the family are treasured moments amidst the wonders of creation.
Family
The most profound moments are the ones shared with my incredible wife and children. Family is the cornerstone of my life — the truest reflection of happiness and fulfilment.
Side Projects
In the pockets of time I carve out: mobile apps, websites, and emerging technologies explored in a sandbox — applying the gifts I've been given in new ways.
Faith intertwines with technology, nature, family & growth.
