-Database Development: Work with Postgres, Snowflake, and ORM tools such as Sequelize or Hibernate.
-Performance & Security: Optimize for scalability and apply best practices for application security.
-Collaboration & Mentorship: Partner with cross-functional teams and mentor junior developers in modern frameworks and practices.
-Quality Assurance: Write unit/integration tests, perform code reviews, and maintain documentation of architectural decisions.
