Engineering at the intersection

of web performance and artificial intelligence

Hi, I’m Chris Josh, a Senior Full-Stack Engineer building performant, scalable, and accessible web applications. I design systems end-to-end, from polished interfaces to backend infrastructure that powers real-world products.

My work now focuses on AI-powered applications — building LLM workflows, RAG systems, and intelligent automation using modern web and AI stacks. I’m particularly interested in applying these systems to solve practical, high-impact problems.
