•        Contribute to the full software development lifecycle (SDLC) of PlatformCraft, including design, development, testing, deployment, and maintenance. This means writing unit and integration tests, participating in code reviews, and proactively improving the overall codebase.

•        Communicate effectively with other squads to ensure smooth implementation and operation of the PlatformCraft.
