The practice
A practice, not an agency.
ArchXS exists around one method: architecture on demand. Architectural effort is sized to the risk of a specific decision, and in its continuous variant, architecture as a service, it replaces a staff architect where a staff position would not hold its own. The method's precondition is a combination that usually drifts apart with seniority: architecture at scale and uninterrupted hands-on delivery.
The practice grew out of two decades in organisations where an architectural mistake is expensive: eight years in global card payments under PCI-DSS, enterprise architecture at a state development bank and on a core banking replacement, technology leadership at a regulated fintech, a national-scale blockchain product, and most recently technology in manufacturing, from the plant floor to e-commerce.
Code is written in parallel. More than a dozen active production repositories, backend systems in two independent ecosystems, web and mobile applications, industrial integrations, custom identity-server extensions, open-source tooling. That body of work is how recommendations get tested before they are handed to someone else.
That is where the scope of this site comes from. You will not find a biography or conference photographs, because they are not the subject of the work. You will find positions, evidence and writing from which a way of thinking can be judged, and that is the only thing anyone really buys in advisory work.
