Mohammad Rukonuzzaman

Senior Platform Engineer

Designing reliable, secure, and scalable cloud-native platforms.

I specialize in designing, automating, and managing scalable cloud and cloud-native infrastructure. I have extensive experience in delivering highly reliable, secure, and performance-optimized systems. Beyond technical delivery, I lead and mentor teams, plan roadmaps, and manage business-aligned technology initiatives with a strong focus on resilience, scale, and platform maturity.

My work spans Kubernetes, platform engineering, infrastructure automation, observability, GitOps, CI/CD, infrastructure security, and production reliability for large-scale distributed systems.
