Writing and technical review
In Guides, I explain practical checks and their limits. In the IT Journal, I document real interventions, projects and technical decisions. When I am both author and technical reviewer, the review date refers to my own check of the material; it is not an independent review.
The experience areas above are stated by the author. The publications below provide documented examples; they are not a list of certifications or guaranteed outcomes.
