A second-time founder (Techstars 2017), he has led award-winning teams across digital marketing, music tech, live sports betting and most recently e-commerce at Tesco, where he pioneered AI-native design systems. His "Design System as a Service" methodology serves 250+ teams across the retailer's digital estate. He has grown engineering teams from 1 to 100+. AI has made creating code cheap. Owning it costs what it always did. Freddie founded Modomics to measure that carrying cost, module by module, in the unit engineering actually spends: hours. The system closes the loop by directing agentic workflows scoped to the toil of keeping code alive, returning capacity to the roadmap.

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.
