• Model data and write efficient SQL for PostgreSQL (schemas, queries, indexes, and migrations)
• Build and integrate APIs (REST and/or GraphQL) and collaborate with frontend teams on contracts and performance
• Contribute to a clean, framework-light codebase; prioritize simple solutions over unnecessary abstractions
• Containerize and run services locally with Docker; contribute to development tooling and scripts
• Write and maintain automated tests (unit/integration), plus clear documentation and READMEs
• Participate in code reviews, share feedback, and learn best practices from senior teammates
• Monitor and troubleshoot issues with logs/metrics; contribute to continuous improvement of reliability
• Collaborate with product and design to scope work, break down tasks, and deliver iteratively

• Strong understanding of TypeScript fundamentals (types, generics, strict mode, compiler options)
• Solid understanding of Node.js internals (event loop, async patterns, error handling, performance basics)
• Practical experience with PostgreSQL (data modeling, SQL queries, basic indexing and migrations)
• Comfortable working without heavy frameworks; able to craft minimal, well-structured services
• Willingness and motivation to learn and work with GraphQL
• Familiarity with Docker (building images, composing services for local dev)
