Hello, I'm
Rakib Khan
I build infrastructure that doesn't break. 7+ years scaling systems on AWS, Kubernetes, and everything in between. You hire me when your infra is fragile, your AWS bill is too high, or your deployments are slow.

About Me
My Journey
I started my tech journey with a deep curiosity for how systems work under the hood. What began as tinkering with Linux servers quickly evolved into a passion for building resilient, scalable infrastructure. Over 7+ years, I've gone from managing a single server to architecting distributed systems that process millions of requests. I believe great infrastructure is invisible — it just works, reliably, every time.
I specialize in transforming fragile, manual-heavy infrastructure into automated, observable, and highly available systems. Whether it's cutting your AWS bill in half, achieving 5-second failover, or shipping code 80% faster with CI/CD — I bring production-grade reliability to every project.
Outside of work, I enjoy exploring new open-source tools, contributing to developer communities, and staying current with cloud-native trends. I also enjoy volleyball and spending time outdoors in the beautiful countryside of Rajbari.
You hire me when:
- →Your infra is fragile
- →Your AWS bill is too high
- →Your deployments are slow or risky
- →You need production-grade reliability
