  • Strong expertise in NodeJS, React/TypeScript, Ruby on Rails, REST/GraphQL APIs, Kafka, PostgreSQL

  • Deep understanding of distributed systems, microservices, and serverless patterns

  • Experience mentoring engineers and setting technical directions

  • Background in working with and evolving established backend architectures

  • Pragmatic mindset focused on performance, maintainability, and readability

  • Clear communicator with strong documentation skills
