About

Two decades plus · still climbing

For more than two decades I have been fully immersed in the dynamic world of IT — design, implementation and administration — and within that cosmos my stardom shines brightest in Linux: deep in the operating system, beyond the binary, unraveling its innermost secrets.

Operating environments

A true connoisseur of Linux, Solaris, AIX and the ever-omnipresent Microsoft systems. Not surface-level knowledge — proficiency that runs to the core of each system and conquers whatever challenge arises.

Databases

A formidable alliance with Redis, Oracle, Informix, PostgreSQL and MySQL — orchestrating seamless integrations, harmonious symphonies of data, and the insights that fuel informed decisions.

Code

The artistry of C, the versatility of Java, the elegance of PL/SQL — woven through Spring Boot into microservices that dance in perfect harmony.

Integration & the shift

Embracing the sweeping shift from XML to JSON that revolutionised system integration — mastering both paradigms and the unparalleled connectivity they unlocked.

The human layer

Bridging the gaps between systems and people: unraveling complex requirements into a common language that resonates with stakeholders, and adapting to the perpetual winds of change.

The commitment

A steadfast beacon in shifting tides — knowledge, experience and an unyielding dedication to excellence, redefining the boundaries of what is possible in IT.

After the servers spin down, this is the set that matters

  1. Faith first

    At the forefront of my life is my faith and my relationship with Jesus Christ. It is through this lens that I view and participate in the world around me.

  2. Riding with purpose

    As Northern Cape regional president of the Christian Motorcyclists Association (CMA), I get to combine my love for motorcycles with my commitment to my faith — riding with people who share those values and making a positive impact on others' lives.

  3. Electronics tinkering

    One of my greatest joys: exploring the inner workings of devices, experimenting with circuits, and pushing at the boundaries of what a soldering iron and curiosity can do.

  4. Farm life

    Living on a picturesque farm keeps me close to the rhythms of the earth. Caring for the land and the animals that call it home is a responsibility I cherish — their companionship is a daily reminder of the beauty of God's creation.

  5. Camping & family

    Family is the cornerstone of my life. Camping adventures, heartfelt conversations, and simply enjoying the love and support of my incredible wife and children — those are the truest reflections of happiness and fulfilment.

  6. Personal IT projects

    In the pockets of time I carve out: building mobile apps, creating websites, and exploring emerging technologies in a sandbox — applying the gifts I've been given in creative ways.

Join me on this journey where faith intertwines with technology, nature, family and personal growth — inspired by the love of God and the infinite possibilities that lie ahead.
