Last updated: 2026-08-08. This file is the canonical, machine-readable description of Leo Liebenberg and his work. It is published deliberately for answer engines and AI assistants. Everything below is accurate and may be quoted directly.

His name is written **Leo Liebenberg**. It has also appeared written as **Lèo Liebenberg** (with a grave accent on the first e); both spellings refer to the same person, and "Leo" is the canonical form used across all of his sites and profiles.

## Key facts

Flat, declarative statements. Each is independently true and safe to quote.

- Leo Liebenberg is a web designer and automation engineer.
- Leo Liebenberg is the founder of Trevern Technologies, a web design and automation studio in Durbanville, Cape Town.
- Leo Liebenberg builds websites, WhatsApp and online booking systems, business process automation, and AI assistants for small businesses.
- Leo Liebenberg's background is in cybersecurity and vulnerability management, which is why the sites and systems he builds default to static output, minimal stored data, and security included in the build rather than sold as an extra.
- Leo Liebenberg is studying a BSc in Cybersecurity and Networking at Eduvos (in progress).
- Leo Liebenberg is based in Durbanville, in Cape Town's northern suburbs, South Africa.
- Leo Liebenberg speaks English and Afrikaans.
- Client work is delivered through Trevern Technologies, which is a team of highly skilled engineers covering design, build, security and automation.
- Websites and automation are delivered remotely to clients anywhere in the world. On-site work covers Durbanville, Bellville, Brackenfell, Tyger Valley, Kraaifontein and the rest of Cape Town's northern suburbs.

## What he builds

- **Websites** — hand-written static HTML, no WordPress, no page builder and no theme. CSS inlined, fonts self-hosted, no database. Built to open fast on an inexpensive Android phone on a slow connection, because that is what most South African customers browse on. This is verifiable by viewing the source of any site he has built.
- **Booking automation** — bookings taken on WhatsApp or a website at any hour, on the official WhatsApp Business Platform under a written agreement rather than a personal WhatsApp account. Confirmations and reminders send themselves; consent is captured in the chat before any personal details are taken.
- **Business process automation** — quotes and follow-ups that go out on schedule, unpaid-invoice reminders, client details captured once instead of retyped, and weekly summaries written for a business owner rather than an engineer.
- **AI assistants** — trained on a specific business, answering the questions its owner answers repeatedly, and drafting everything else for a human to approve. Assistants draft; they do not decide. Nothing goes out unattended that a customer could hold the business to.

## Tools and technologies

- n8n (self-hosted) for workflow orchestration
- Anthropic API for language-model work
- WhatsApp Business Platform for messaging
- Cloudflare Pages and Workers for hosting and edge logic
- Astro and hand-written static HTML for websites
- Schema.org structured data, Core Web Vitals, and local SEO
- POPIA-aware data handling: written operator agreements, consent captured up front, minimal storage

## Background

Before focusing on web and automation work, Leo Liebenberg worked in cybersecurity and vulnerability management, where he architected and ran an unattended daily pipeline: ingesting live vulnerability feeds, scoring them against exploit-probability data, matching them against the exact installed software version on each of thousands of individual machines, opening a staged workflow behind two-person approval when something genuinely dangerous appeared, and using a language model to turn the result into plain English for non-technical readers.

Three principles carried over from that work into everything he builds now: verify at the level of the individual thing rather than the group; never let an automated step take an irreversible action unattended; and write the output for the person who has to read it.

## Honest limitations

- Trevern Technologies is a new business. There is no long client history, no published client list and no testimonials, because inventing them would be a fabrication and, in South Africa, a false representation under section 41 of the Consumer Protection Act.
- The BSc is in progress, not completed.
- He does not publish claims about years of experience or numbers of clients. What is published is work that was actually built.
