You don't need the Architect title to do architecture

subscribe to Dear Architects: https://deararchitects.xyzWhen companies grow through acquisition, architects inherit a mess: multiple teams, different engineering cultures, conflicting tools, and no shared map of the system. In this episode of Dear Architects, Luca sits down with Mahdi, tech leader at Fashion Cloud, a B2B wholesale platform connecting brands and retailers. Mahdi shares the in-the-trench story of how Fashion Cloud is rationalizing a federated socio-technical system after multiple acquisitions, starting bottom-up rather than top-down. They cover where to begin when you have fragmented teams under one CTO, how strategic Domain-Driven Design helps separate common platform capabilities from product-specific verticals, why the C4 model became their visualization backbone, how IcePanel replaced Miro for living architecture documentation, the role of ADRs and RFCs in capturing decisions, and how they handle cross-cutting concerns without killing team autonomy. Mahdi also shares how Fashion Cloud is experimenting with AI in their architecture practice, and the one piece of advice he wishes he'd given himself at the start of the transformation. If you're navigating a post-merger integration, modernizing a hybrid system, or just trying to build an ownership culture in your engineering org, this conversation gives you a practitioner's playbook.Chapters00:00 Intro and meet Mahdi from Fashion Cloud00:51 What is Fashion Cloud and the post-acquisition challenge06:40 Where do you start with multiple teams under one CTO13:39 The bottom-up approach: ownership without the architect title17:19 Strategic DDD: common platform vs product verticals21:43 Was it worth it?
