As an experienced professional with a deep understanding of open source technologies, I'm confident in my ability to diagnose and rectify the connectivity issues you are facing with Python/Flask and DynamoDB. My proficiency extends beyond just the requisite skills of Python, Flask, DynomoDB and a monolithic architecture - I have an in-depth knowledge of multiple databases including Oracle, PostgreSQL, MongoDB, MySQL, and Redis, all of which contribute to a holistic understanding of data infrastructure.
My experience with critical 24x7 environments has honed my troubleshooting skills to swiftly identify and resolve potential problems before they escalate. This is complemented by my familiarity with HA/DR architectures in cloud environments including Azure, GCP, AWS that will ensure any necessary changes or updates are deployed seamlessly without disrupting the current production.
Lastly, one attribute I value highly is keeping up-to-date with emerging tools and approaches. With a keen interest in automation, my knowledge spans from IaC to CI/CD pipelines and containerization using Kubernetes. Recognizing the significance of monitoring in maintaining robust systems, I am also well-versed with various monitoring tools like Prometheus and NewRelic that could give me crucial introspectivity into this issue.
