PostgreSQL

The Enterprise-Grade Open Source Database

For modern, complex applications requiring data integrity and advanced features, PostgreSQL has been my go-to relational database. Its robustness and rich feature set made it the ideal choice for mission-critical systems at the Directorate General of Taxes (DJP).

The DJPConnect and SIKKA projects were both built on a PostgreSQL backend. My work involved designing schemas, writing queries, and leveraging its features within a Symfony (Doctrine ORM) environment. I have experience with its powerful indexing, transaction management, and data types.

Key Competencies

• Advanced SQL: Utilizing PostgreSQL-specific features and advanced SQL constructs.
• Data Modeling: Designing robust schemas for complex enterprise systems.
• Performance Tuning: Analyzing query plans and optimizing performance for large datasets.
• ORM Integration: Deep experience using PostgreSQL with ORMs like Doctrine.
• Cloud Environments: Working with managed PostgreSQL services on platforms like GCP (Cloud SQL) and Alibaba Cloud (RDS).
