I am looking for a professional with expertise in building management systems and IoT solutions to help develop a comprehensive system tailored for residential complexes. The solution should manage energy efficiency and monitoring, security systems and access control, and HVAC and climate management. This will be a standalone system, not requiring integration with existing setups. Additionally, I need an application to control the IoT solution, compatible with both mobile platforms (Android/iOS) and as a web-based application. The deliverables include: - A fully functioning IoT solution addressing the specified management areas. - An intuitive application for end-user control, optimized for mobile and web usage. Please ensure your proposals detail how you plan to approach this project, including timelines and any technologies or frameworks you recommend using.
