• Strong ability to work independently, make sound technical decisions, and deliver features efficiently with minimal supervision.
• Production experience building REST APIs in Java, using Quarkus, Spring Boot, or an equivalent JVM framework; ability to quickly understand and extend Quarkus-specific patterns such as CDI, RESTEasy Reactive, and Panache.
• Production-grade experience with React and TypeScript, including modern React hooks and Next.js App Router patterns.
• Strong PostgreSQL experience, including schema design, migration strategies (Flyway or Liquibase), query optimization, and index design.
• Hands-on experience with Docker and containerized local development workflows.
• Strong focus on production quality, including security, performance, migration safety, maintainability, and reliability.
• Experience writing and maintaining integration tests against real infrastructure, with good judgment around what should and should not be automated.
