Summary
As hands on as I can be I combine my years of experience as an Engineer and Software Architect with in-depth infrastructure and cloud vendor knowledge to help my teams design and navigate through complex business/product functional and non-functional requirements.
I strongly believe that we need to understand the reasoning and the foundation of any process, framework or technology before we use it in order to apply it efficiently without losing clear sight on the organization identity and goals.
