• Monitor and troubleshoot database performance, identifying and resolving bottlenecks.

• Ensure data security and compliance with industry standards, implementing encryption, access control, and auditing policies.

• Optimize stored procedures, triggers, and functions for maximum efficiency.

• Database:
  Postgre
  
  SQL (Primary), AWS RDS, SQL.
• Big Data & ETL:
  Apache Kafka, Airflow, dbt, Snowflake (nice to have).
• Performance Optimization:
  Indexing, Partitioning, Query Optimization, Caching.
• Security:
  Data Encryption, Role-Based Access Control (RBAC), Auditing.
• Tools & Dev Ops:
  Liquibase, Flyway, Terraform, Kubernetes (for DB management).
• Scripting & Programming: SQL, PL/pgSQL, Python, Bash.
