  • Deep understanding of mobile performance, memory management, profiling, and platform‑specific constraints.

  • Strong communication skills for clearly reporting progress, blockers, risks, and trade‑offs to technical and non‑technical stakeholders.

  • Experience with Git‑based workflows and collaborative development practices (code reviews, documentation, CI/CD is a plus).
