Full-Stack Developer – Build a Cleaning Management SaaS Platform in Phases.

Full-Stack Developer / Technical Development Partner – Build a Cleaning Management SaaS Platform in Phases (MC&O) Project overview I am looking for an experienced full-stack developer who can become a long-term technical development partner for a new software platform called MC&O (Marcos Cleaning & Maintenance). The software is being developed for my existing cleaning company, Perfectclean Zeeland, in the Netherlands. We currently have approximately: 15 employees 12 customers 15 cleaning locations The goal is to develop a professional management platform specifically for cleaning companies. Initially, we will use it within our own company. In the future, we want to offer it as a SaaS product to other cleaning companies. I am not a programmer, so I need someone who can explain technical decisions clearly, advise me and help build the right foundation for future development. Development approach I want to develop the platform step by step. For the first assignment, I have an indicative budget of €2,000–€3,000. I understand that this budget is not sufficient to build the complete platform. I therefore want to agree on a realistic and clearly defined first working version (MVP). The developer should advise which functions can realistically be delivered within this budget. Initial MVP requirements The first version should focus on the essential daily operations of my cleaning company. Potential MVP features: Secure login and user management. Basic roles and permissions. Customer management. Cleaning location management. Employee management. Day and week planning. Assigning employees to cleaning locations and shifts. Recurring cleaning schedules. A simple mobile-friendly employee environment. Employee schedule overview. Basic clock-in and clock-out functionality, if feasible within the budget. Please explain which features can be included in the first delivery and which should be postponed. Future development The platform should be designed so that it can be expanded with: Leave requests and leave balances. Sickness registration and replacement suggestions. GPS-verified time registration. Multilingual employee application. Smart scheduling assistance. Variable planning for hotels and holiday parks based on occupancy. Quotes, contracts and invoicing. Yuki accounting integration. Financial reports and profit margins per customer. Customer portal. Quality control and complaints. Multi-tenant SaaS functionality. 30-day free trial and subscription plans. These features do not all need to be developed immediately. However, the initial technical architecture should take future expansion into account. Technical expectations I am open to your professional recommendations. Possible technologies include: React / Next.js TypeScript Node.js PostgreSQL Google Cloud or another suitable cloud platform PWA or mobile-friendly web application Please explain your proposed architecture and why you recommend it. What I expect from you I am looking for someone who: Has experience building business management software. Has experience with SaaS platforms. Understands database design and user permissions. Can build scalable and maintainable software. Can advise on technical architecture. Communicates clearly in English. Can work with clearly defined milestones. Is interested in a possible long-term collaboration. Ownership and delivery The following conditions are important: I must receive the source code for the custom-developed software. The code repository should be accessible to me. Cloud accounts and important services should be registered in my company's name or be transferable. Technical documentation must be provided. The software must be tested before delivery. Payments should be linked to agreed milestones. No additional work or costs without my approval. Third-party software and open-source components must be clearly identified, including their licence conditions. What to include in your proposal Please answer the following questions: What similar software projects have you developed? Can you show examples of SaaS or business management platforms? What would you include in an MVP with a budget of €2,000–€3,000? What would you postpone until later phases? What technology and architecture would you recommend? How long would the first version take? What would your estimated costs be for future development? What are the expected monthly hosting and maintenance costs? Are you available for long-term collaboration? Please provide a realistic proposal rather than promising to build everything within the initial budget. I am looking for a reliable technical partner who can help turn MC&O into a professional software platform for the cleaning industry.
