About

I’ve spent about seven years in SEO, most of it below the content layer: server logs, HTTP headers, rendering, Core Web Vitals and structured data. I read a website the way an engineer reads a system. What gets requested, what comes back, what breaks, and what the logs say actually happened.

That habit has a history: an IT systems development diploma, then years as a marketing analyst and web master before SEO became the main line, and an Honours in Information Technology in 2025. I still build the tools I use, in Python: redirect mappers, audit pipelines, scrapers. Today I’m the technical SEO specialist for Practice Promotions, a US healthcare marketing firm, overseeing a portfolio of 40 clients, and I run YSM Digital, my own studio in Johannesburg.

Where I’m heading is security. DNS, headers, logs and bot behaviour were always half of the job; now I’m studying the other half properly, starting with ISC2 CC and CompTIA Security+, with Hack The Box and TryHackMe alongside. The aim is a security operations role, built on the same evidence-first habits that made me good at search.

    I run the technical SEO strategy across the agency’s clients and oversee SEO performance for a portfolio of 40: site audits, crawl errors, Core Web Vitals and structured data. I co-developed the Net SEO Score, a tracking system that flags ranking drops before clients notice them, and built the Python scraper that feeds it from Agency Analytics.
