Experience with data modeling and optimization for performance and scalability is valued.
Demonstrated full-stack development experience, with a solid understanding of integration and communication between front-end and back-end systems.
Ability to contribute across the entire application stack.
Proven experience integrating services and systems through APIs (e.g., RESTful, gRPC) or direct communication over a bus, focusing on efficient, scalable, and secure integration patterns.
Familiarity with microservices architectures and event-driven systems is a plus.
A strong commitment to software quality, including expertise in testing methodologies (e.g., unit, integration, end-to-end).
Possesses a 'test-to-break' mindset, with the ability to identify vulnerabilities and design resilient, fault-tolerant software.
