Karthick Shanmugam

I'm Karthick, a Staff Web Platform Developer at SIXT, currently focused on making AI coding agents safe and productive inside large React codebases — without letting them erode the architecture boundaries that make them work. Beyond AI, I spend my time building JavaScript platforms, refining workspace-driven architectures, and designing the infrastructure layers that tie everything together. From Nx/pnpm monorepos to multi-instance microfrontends, I focus on the patterns, boundaries, and shared capabilities that help application teams scale without friction. I love diving into how large JS systems behave in the real world and sharing practical lessons that simplify them.
