About Bernardo

Senior Software Architect | Distributed Systems & .NET Platforms 10

Over 15 years of international experience in designing critical enterprise architectures. Specialist in establishing "Golden Paths", governance-as-code, and accelerating technical velocity within complex ecosystems (multi-stack legacy towards cloud-native targets).

Profile independently validated 100% by Toulouse Métropole and 96% by European Dynamics (European Commission markets) on architecture evaluations.

🎯 Areas of Expertise:
Architecture & Governance: Distributed systems (DDD, CQRS, Event Sourcing, Saga Orchestration), writing DAT (Technical Design Documents) and steering high-level technological choices.

Platform Engineering & Tooling: Creation of reusable technical assets, deterministic internal frameworks (AOT-First, Roslyn Source Generators).

Messaging & Cloud: High-throughput event-driven architectures (Kafka, RabbitMQ, Azure, AWS, Kubernetes).

DevSecOps & Security: Securing CI/CD pipelines and regulatory compliance (OAuth2, RBAC, ISO 27001, GDPR).

🛠️ A Unique Asset: The Franz Framework
Author and solo developer of the Franz Framework (+550K NuGet downloads, 61 packages), an enterprise architecture accelerator natively designed for .NET 10. It integrates custom static analyzers (Franz Tribunal) to automate adherence to technical guidelines at compile time.

👥 Leadership & Impact
Accustomed to collaborating with business and technical management. Proven track record of mentoring and leading developer teams of up to 60 people, while halving time-to-market.
