• Strong grasp of relational databases (PostgreSQL, MySQL) and practical data modeling.
• A self-starter mentality with a passion for quality and ownership—from idea to production.
• comfortable leveraging AI coding tools to boost productivity, explore solutions faster, and enhance code quality without compromising craftsmanship.
