  • Advanced SQL and procedural extensions (PL/SQL, T-SQL), including complex query optimization, window functions, and CTEs.
  • Strong data modeling (conceptual/logical/physical), normalization/denormalization, and schema design for OLTP/OLAP.
  • Experience building and maintaining ETL/ELT pipelines (e.g., SSIS, Informatica, Talend, dbt) and orchestration (e.g., Airflow).
  • Knowledge of application frameworks, microservices, and containerization/cloud patterns (e.g., Docker, Kubernetes).
  • Ability to review test plans and test data; hands-on experience with CI/CD, automated testing, and migration tooling (e.g., Liquibase).
  • Cross-platform interoperability understanding (JDBC/ODBC, APIs, NT/Intranet), and use of multiple toolkits.
  • Strong grasp of security/privacy controls across the stack: secure coding, encryption, masking, auditing, and compliance fundamentals.
