About David
DevOps engineer with hands-on experience in cloud infrastructure and team leadership
Hey there! I'm David
I've been working in DevOps and cloud infrastructure for over 9 years now, mainly with AWS and Azure Platform. I really enjoy the challenge of building scalable systems and leading technical teams. Recently, I've been working a lot with Azure Stack deployments helped a construction project data and information company migrate from Azure to AWS infrastructure with Native Cloud Architecture. My focus has also expanded to cloud computing by leading cloud migrations and modernization initiatives by using rehost, replatform, and refactor or re-architect strategies for technology delivery.
