## About the Role

Strong grasp of networking fundamentals, HTTP protocol, connection pooling, and data serialization.

 - Solid knowledge of database internals such as indexing, locking, query plans, and transaction isolation.
 - Ability to make and justify architectural decisions (monolith vs. microservices, REST vs. GraphQL, synchronous vs. asynchronous communication).
 - Skilled in evaluating trade-offs related to consistency, latency, payload sizes, and developer experience for data layer design.
 - Experience selecting and implementing appropriate database technologies (SQL vs. NoSQL) based on application needs.
 - Focused on enterprise-grade reliability, including defensive programming, input validation, data masking, and security best practices.
 - Ensures system resilience and fault containment, particularly in financial or mission-critical platforms.
 - Practices clean code principles, separation of concerns, automated testing, and maintains readable abstractions to aid team productivity.
 - Proficient in building and operating server-side applications and distributed microservices in production environments.
 - Experienced with designing and consuming RESTful APIs and event-driven architectures (especially with Apache Kafka).
 - Hands-on work with both relational (e.g., PostgreSQL, MySQL, Oracle) and NoSQL (e.g., MongoDB, Cassandra, DynamoDB) databases.
 - Familiar with automated testing (unit, integration, regression) and CI/CD toolchains.
 - Strong debugging, root-cause analysis, and performance optimization skills.
 - Preferred technical stack includes Java/Kotlin (or similar), REST, GraphQL, RAML, OpenAPI, Gradle/Maven, Docker, Kubernetes, and Jenkins/GitLab CI.
 - Comfortable modernizing legacy codebases and migrating to modern service architectures.
 - Relevant technologies encountered: Kotlin, Gradle, REST, GraphQL (GQL), RAML.
