  • Drive the adoption of a microservices-oriented architecture, defining service boundaries and communication protocols (REST, GraphQL, gRPC).
• Technical Leadership:
  • Provide technical guidance and mentorship to software development teams, including front-end (Angular) and back-end (Node.js/Python) engineers.
  • Lead architectural reviews, code reviews, and design sessions to ensure adherence to architectural standards and high code quality.
  • Identify technical debt and proactively propose and plan for refactoring and modernization initiatives.
