hardus@havenga:~$ cat about.txt

For more than two decades I have been fully immersed in IT — design, implementation, and administration across a multitude of projects. That journey has made me a connoisseur of operating environments: Linux, Solaris, AIX, and the ever-omnipresent Microsoft systems. My expertise goes well past the surface — it reaches into the core of each system.

Databases are trusted allies: I wield Redis, Oracle, Informix, PostgreSQL, and MySQL with confidence, orchestrating seamless integrations and extracting the insights that fuel informed decisions.

Programming is where the creative spirit comes out — the artistry of C, the versatility of Java, and the elegance of PL/SQL. With Spring Boot I build microservices that work in harmony, delivering streamlined functionality for modern applications.

My stardom shines brightest in Linux. I have peered beyond the binary and unravelled its innermost workings — which is how issues get resolved efficiently and limitations get defied.

I have also ridden the sweeping shift from XML to JSON — a transformation that revolutionised the fabric of systems integration. I am at home in both paradigms and in the messy realities of connecting them.

The journey is not technical mastery alone. I bridge the gaps between systems and between people: unravelling complex requirements, forging a common language with stakeholders, and aligning technology with the business — while adapting to the perpetual winds of change.

# exit 0 — dedicated to excellence, still redefining what is possible.

Faith first. At the forefront of my life is my relationship with Jesus Christ — it is the lens through which I view and participate in everything else on this page.

motorcycles & ministry

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

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.

farm life & outdoors

Life on a picturesque farm — caring for the land and the animals that call it home, connected to the rhythms of the earth. Camping trips with the family are treasured memories in the making.

animals

Animals hold a special place in my heart — from beloved pets to the farm's residents, their companionship is a daily reminder of the beauty of God's creation.

family

The cornerstone of it all: my incredible wife and children. Meaningful activities, heartfelt conversations, and simply enjoying one another — the truest reflection of happiness.

personal IT projects

In the pockets of carved-out time: building mobile apps, creating websites, and exploring emerging technologies in a sandbox — applying the gifts I've been given in creative ways.# where faith intertwines with technology
