• Deep expertise in Spring Boot, Mybatis, and microservices architecture.
• Strong understanding of REST APIs, asynchronous messaging (Kafka, RabbitMQ), and event-driven systems.
• Hands-on experience with databases — both relational (PostgreSQL/MySQL) and NoSQL (MongoDB/Redis).
• Experience deploying and managing applications on AWS, with working knowledge of Docker, Kubernetes, and CI/CD pipelines.
• Familiarity with security frameworks and standards (OAuth2, JWT, encryption, PCI DSS).
• Proven ability to design and deliver high-availability, low-latency, and fault-tolerant systems.
• Excellent problem-solving, debugging, and communication skills.
