I started as a technical consultant for Sistema Vitto's.It all started as a business concern with performance, in face of their growth expectation.Thus, I've reviewed all of their application architecture and their infrastructure.So far, we were able to reduce 60% of the costs, while supporting a growth of 25% of their clients. And letting them 10% faster on average.Now, with the new architecture (domain driven design + microservices), they are able to refactor their applications faster and safer than before.Today I do consulting for a handful companies.
