This is a little info about myself:
I am a Staff-level Engineer with an 18-year evolution from medical-device firmware to leading large-scale AWS and Azure cloud migrations across FinTech, Retail, and Healthcare. I specialize in robust system design, building secure, compliant architectures rooted in industry best practices.
I also am deeply invested in mentoring high-performing teams, collaborating with stakeholders to turn complex requirements into business-aligned solutions, while embracing a lifelong learner mindset.
