Damandeep Singh.

Lead Software Engineer (Forward Deployed)Solutions ArchitectEngineering Manager

Expert in bridging the gap between highly robust frontend UI architectures (React/Next.js) and complex backend microservices. I specialize in migrating legacy monoliths to modern, event-driven MACH (Microservices, API-first, Cloud-native, Headless) architectures. I act as an organizational multiplier by enforcing global quality gates, WCAG AA compliance, and spearheading AI-augmented developer tooling that scales productivity across massive engineering organizations.
