– Practical experience working with AWS CDK or other Infrastructure as Code tools.

– Solid understanding of serverless architectures and event-driven systems.
– Experience with affiliate traffic–driven systems or traffic routing solutions.

– Familiarity with Datadog or similar monitoring tools.

– Exposure to AI / ML–driven logic or data-based decision systems.

– Experience building and supporting production systems with real traffic.

– Ownership mindset and readiness to independently drive the project forward.
