* Collaborate with backend, SRE, security, and product teams to ensure reliable, secure, and scalable solutions.
* Contribute to CI/CD pipelines, testing strategies (unit, integration, e2e), and release processes.
* Participate actively in Agile ceremonies; break down work, estimate, and deliver iteratively.
