  • Strong hands-on experience with database design and development across MS SQL, Oracle, and NoSQL platforms (e.g., Couchbase), including schema design, stored procedures, and query optimization.
  • Solid understanding of microservices architecture and design patterns, with the ability to design, build, and maintain distributed, loosely coupled services.
  • Proficiency in RESTful API design, development, and integration, including experience consuming and exposing APIs across complex enterprise systems.
  • Familiarity with DevOps tools and CI/CD pipelines, including Harness, Tekton, and GitHub, with practical experience in deployment automation and version control workflows.
  • Proven ability to translate business and functional requirements into technical user stories, provide effort estimates, and deliver code that meets project and compliance standards.
