Bottega IT Minds | Circle K
I'm an architect and seasoned software engineer with over 15 years of experience building and evolving large-scale, product-oriented systems.
I work close to the trenches, helping teams design APIs and navigate architectural decisions around ownership, boundaries, and team autonomy - keeping myself as a hands-on expert.
I'm a mentor and trainer at Bottega IT Minds, where I teache Domain-Driven Design pragmatically applied in Microservice architecture supported by AI.
I'm experienced conference speaker, consistently well-rated by attendees, known for practical talks that attract full rooms and spark in-depth discussions.
