PostgreSQL

a. Object-Relational Mapping¶

I am proficient in working with Object-Relational Mapping (ORM) tools to seamlessly integrate relational databases with object-oriented programming. Using PostgreSQL, I efficiently map database tables to application objects, simplifying data queries and operations. My experience includes working with popular ORM libraries to handle database migrations, optimise queries, and maintain data integrity within large-scale applications.

b. Schema Design¶

I have expertise in designing robust database schemas for PostgreSQL, ensuring efficient data storage and retrieval. My skills include normalising data structures, defining relationships between tables, and optimising indexes for performance. I prioritise creating scalable and maintainable schemas that support the evolving needs of the application, minimising redundancy and improving data consistency.

c. Stored Procedures¶

I am skilled in writing stored procedures in PostgreSQL to encapsulate business logic and optimise database performance. My experience includes creating complex procedural code using PL/pgSQL, handling transaction control, and integrating data validation. By leveraging stored procedures, I enhance database efficiency, reduce application logic complexity, and ensure consistency in database operations.

d. Supabase¶

I have experience with Supabase, an open-source alternative to Firebase, built on PostgreSQL. I use Supabase to develop real-time applications with features like authentication, database, storage, and API integration. My skills include managing user data securely, building and querying databases, and utilising Supabase's real-time subscription capabilities to create responsive, interactive applications.

e. Views¶

I am proficient in creating and managing Views in PostgreSQL to simplify complex queries and provide a logical representation of data. I design views to abstract underlying table structures, enhance data security by limiting access to specific data, and improve query readability. My expertise includes optimising views for performance and using materialised views to cache and quickly retrieve frequently accessed data.
