SQL & Databases

SQL and database management are crucial components of my full-stack development skills. Through formal coursework in database management and CS275 (Database Integration), combined with practical experience in CS50W using SQLite, I've developed strong database design and implementation abilities. PostgreSQL is my personal favorite, and I'm highly proficient in implementing it across applications and infrastructure, including migrating data from on-premise solutions to cloud environments.

Expertise Areas

SQL Fundamentals

• Query Design - SELECT, JOIN, aggregation, and complex queries

Why I Love SQL & PostgreSQL

PostgreSQL has become my go-to database because of its reliability, powerful features, and excellent performance. I love the precision and logic of SQL - designing an efficient database schema and writing optimized queries feels like solving puzzles. Understanding how to properly structure and query data has been fundamental to building robust applications. The experience of migrating data from on-premise to cloud solutions taught me how databases work at an infrastructure level, making me confident deploying and managing databases in any environment.

Current Focus
