- Pragmatic experience with Node.js and an understanding of how to manage and migrate a monolithic or service-based system.
- Deep knowledge of database principles (PostgreSQL preferred) and high-performance data access patterns (using tools like Redis).
- Expertise in modern infrastructure: Docker, Kubernetes, and a major cloud provider (GCP/AWS).
- A strong belief that testing, observability, and clean architecture are not optional.
- An innate curiosity and a passion for solving complex problems, whether they're in code or on a whiteboard.
Why You'll Love Working Here:
