How are the technical claims in these articles verified?
Each article is grounded in a specific, named project documented on the Work page, and cites authoritative third-party sources where they support a general technical claim. MQ's own experience is kept clearly distinct from cited third-party documentation.
Who writes these articles?
Muhammad Muzammil Qureshi, Chief Technology Officer and Chief Operating Officer, writing directly from the architecture decisions and constraints of the platforms named in each article.
