Previous experience developing similar platforms will be an added advantage. WHEN SUBMITTING YOUR PROPOSAL, PLEASE INCLUDE: 1. Examples or links to similar platforms you have developed. 2. Your recommended technology stack. 3. Your proposed approach to developing the platform. 4. Estimated development timeline. 5. Total project cost, including any third-party integrations. 6. Whether you recommend a web application, mobile application or both, and why. 7. Details of post-development support and maintenance.
