From Dogma to Culture: redefining Modern Software Architecture for the Future

In 2026, software architecture can no longer be approached as a top‑down, slow, and disconnected discipline.

By taking a critical look at historical approaches (TOGAF, big upfront design, Waterfall cycles) and today’s challenges (technical debt, microservices complexity, integration issues, security, performance), I’ll share a pragmatic, team‑centered, delivery‑focused perspective — one that reflects what developers actually experience every day.

The modern architect is no longer a technical oracle or a guardian of abstract standards. She/he is a cultural facilitator, responsible for ensuring flow, coherence, code sustainability, and for creating the conditions that allow teams to deliver frequently, confidently, and safely.

This session reframes architecture as a narrative and socio‑technical function: “build the right thing, build the thing right, with the right people.”

My goal is to offer a clear synthesis of what developers expect from architecture and architects today: less dogma, more purpose; less control, more collaboration; less rigidity, more adaptability.

And above all, a shared culture that withstands time, change… and AI.
I’ll show why this is a cornerstone for the present — and for what comes next.
