  • Proficient in database design and management (SQL and NoSQL).
  • Proven experience with monolithic to microservices transition, API design (REST & GraphQL), and secure authentication systems.
  • Strong understanding of clean code principles, SOLID, DRY, and test-driven development (TDD).

  • Exposure to serverless architectures and container orchestration (Kubernetes, ECS).
  • Background in startup environments or greenfield projects is a plus.
