A project agreement should outline detailed project scope, specific deliverables, timelines, and milestones. It should specify the technologies and frameworks to be used and include any design guidelines or brand standards. Ensure there is an agreed-upon process for feedback and revisions to avoid misunderstandings.
To onboard a frontend engineer effectively, provide a comprehensive brief that includes all necessary project information. Share access to any collaboration tools, code repositories, and relevant documentation. Arrange an initial meeting to discuss the project goals, technical stack, and communication channels, ensuring the freelancer feels integrated from the start.
