👋 Hi, I'm Tuhin Zaman, a Cloud DevOps Engineer at VistaJet with 8+ years of experience in DevOps and cloud engineering.
I started as a System Administrator before moving into cloud and DevOps engineering. I work on production Kubernetes and CI/CD, with a focus on reliable, resilient cloud platforms, safe deployments, recovery and AWS cost optimization.
📍 Buffalo, New York · Open to remote Senior DevOps, Platform Engineering and SRE roles.
| Project | What to explore |
