  • Strong understanding of distributed systems, microservices, and event-driven architecture.
  • Experience building scalable, production-grade APIs and real-time systems.
  • A passion for automation, intelligent workflows, and simplifying complex processes.
  • A builder’s mindset — autonomous, fast, pragmatic, and product-oriented.
  • The ability to lead initiatives and deliver high-quality software end-to-end.
