  • Ensure system performance and scalability through optimization techniques and load testing.
Database Management:
  • Design and maintain highly available, fault-tolerant databases with Aurora and Postgres.
  • Optimize SQL queries and database performance for large datasets.
Production Support and Testing:
  • Provide production support and troubleshooting for backend services, including performance tuning and bug fixes.
  • Apply Test Driven Development (TDD) principles to develop comprehensive test cases.
  • Support system testing, including unit, integration, and performance tests.
Technical Skills:
  • Strong experience with Java and Spring Boot for backend development.
  • Proficient in real-time data processing with Kafka and Amazon MSK.
