• Proficiency in RESTful API design and implementation


• In-depth knowledge of PostgreSQL and ORM frameworks like Sequelize


• Hands-on experience with Docker, Kubernetes, and container orchestration


• Understanding of payment processing systems, security requirements, and gateway integrations (e.g. Adyen) is a plus

• Comfort with asynchronous programming and WebSocket implementations


• Experience with dependency injection frameworks (e.g. tsyringe)

• Understanding of API security, rate limiting, and observability tools

• Work on a modern, technically challenging platform used by millions
