  • Extensive hands-on experience with AWS cloud services (EC2, Lambda, RDS, DynamoDB, SQS, SNS), building scalable and maintainable cloud-native applications
  • Proven experience in developing high-performance distributed systems, focusing on performance optimization, security, and fault tolerance
  • Strong ability to collaborate with cross-functional teams, contributing to technical leadership through code reviews, architecture discussions, and mentoring junior engineers
  • Deep knowledge of backend technologies including RESTful APIs, GraphQL, message queues, and modern build tools (Gradle, Maven)
  • Expert understanding of database design, caching strategies, and backend testing frameworks, ensuring robust and maintainable code

Get bonus points if you also have...

  • Experience with large-scale, high-throughput distributed systems
  • Knowledge of security best practices and payment processing systems
