The pattern is always the same: define the standard, build the first version myself, prove it in production, then turn it into a playbook the team can own and scale.</p> <p>Today I lead the Platform team — spanning DevOps and Data Engineering — at a multi-region live-commerce streaming platform, building the infrastructure, data, security, and compliance foundation. Before that I designed and operated a multi-cluster EKS platform for 100+ services.</p> <h2 id="on-this-blog">On this blog </h2><p>I pry open the lid on things I use every day but never look inside.</p> <p>The flagship series, <strong>[Build Your Own Datacenter]</strong>, builds a datacenter from the ground up — starting with bare metal and virtualization, then implementing an AWS-compatible cloud (<a class="link" href="https://github.com/j2eff-we/mincloud" target="_blank" rel="noopener" >mincloud</a>) on top of it.
