@Microlent

Hello, Your vision of building AI-powered SaaS applications for both web and mobile platforms aligns perfectly with our expertise. We specialize in developing scalable SaaS products, business automation platforms, AI-integrated applications, and cross-platform mobile solutions from concept to production. Recent relevant projects include: • Fledger – Financial SaaS Platform • Notely AI – AI Productivity Application • AnswersAI – AI Learning Platform • MyMagicMoments – Mobile Platform • Hire Heroes AI – AI Recruitment Solution For your MVP, I would recommend Flutter for Android, iOS, and Web from a single codebase, combined with Node.js or FastAPI backend, PostgreSQL database, secure authentication, payment integration, push notifications, and AI-ready architecture for future automation features. We can support the complete product lifecycle: • UX/UI Design • Architecture Planning • MVP Development • AI Integration • Testing & Deployment Our development approach focuses on clean code, Git-based workflow, scalable architecture, deployment documentation, and long-term maintainability. A few questions: 1. What is the primary purpose of the first SaaS application? 2. Which AI capabilities are most important initially (chatbot, automation, content generation, analytics, etc.)? I would be happy to discuss the MVP roadmap and establish a long-term collaboration. Regards, Rajesh Rolen Microlent Systems

Hello, Your project aligns well with my experience. I have 6+ years of experience building SaaS platforms, web applications, and mobile apps using Flutter, React Native, Node.js, Laravel, and modern cloud architectures. For a cross-platform solution, I would recommend Flutter, allowing us to maintain a single codebase for Android, iOS, and Web while keeping development efficient and scalable. On the backend, I can work with Node.js, FastAPI, or Go and design the system with AI integration, microservices, and future scalability in mind. I can support the complete lifecycle, including UX/UI design, development, testing, deployment, Play Store publishing, documentation, and ongoing maintenance. All code will be delivered through a clean Git repository with proper architecture documentation to ensure long-term maintainability. Some of my recent work includes SaaS platforms, AI-integrated applications, real-time systems, marketplaces, and mobile applications published on both Google Play and the App Store. A functional MVP can typically be delivered within 6–10 weeks, depending on the feature scope. I would be happy to discuss your requirements in more detail and provide a more accurate timeline and roadmap. Looking forward to learning more about AIPOL SA and your upcoming products.

Hello, this is a broad SaaS build with web, Android, billing, auth, and AI extension points, so the architecture matters more than the first feature list. The real engineering risk is not the FastAPI backend itself; it’s keeping identity, billing state, notifications, and future AI workflows cleanly separated so the product stays maintainable after the MVP. I’ve built several production systems like this where the backend had to be stable first, with room for later automation and AI features. For your server side, Python + FastAPI is a sensible choice if you want a clean API layer and open integration paths for AI services. The closest references are Dent-Cloud for SaaS architecture, auth boundaries, and production deployment, and DocIntel AI for FastAPI services, automation pipelines, and AI-ready system design. I usually structure systems by separating account/auth, billing, notification events, and domain logic into distinct service boundaries, even if they deploy simply at first. That keeps mobile, web, and admin flows from becoming tightly coupled. If useful, I can sketch the MVP architecture and define the service boundaries, data model, and release path for web plus Android packaging. Clifton

@jaroslavcaprata

Hi, there. I’ve reviewed your requirements and am very interested in a long-term collaboration involving SaaS, Android, and AI-powered applications. I have experience building full-stack platforms using React, Flutter, Node.js, Python, and FastAPI, including web applications, mobile apps, API integrations, admin panels, and scalable cloud architectures. For projects like yours, I typically recommend a shared codebase approach using Flutter or React Native for mobile and modern backend services with FastAPI or Node.js, ensuring faster development and easier maintenance. My focus is always on clean architecture, secure development practices, well-structured Git repositories, and documentation that allows clients to manage and extend their products independently. I am comfortable handling the full cycle from UX/UI design and MVP development to testing, deployment, Play Store preparation, and post-launch support. The fact that you are planning multiple applications makes it especially important to establish strong technical foundations from the beginning, with scalability and AI integration in mind. I would be glad to learn more about your current projects and discuss how we can build a productive long-term partnership. Thanks.

Hi, I can develop a comprehensive SaaS application that seamlessly functions on both desktop browsers and mobile devices. The mobile part will initially run on Android, requiring an APK file and Google Play configuration. I aim for ongoing collaboration to create multiple applications. Key MVP modules include secure login management, payment integration, push notifications for Android and web, and additional AI-driven automation suggestions we'll discuss together. I have experience with frameworks like Flutter, React Native, and Electron to efficiently handle both platforms from a single codebase. I prioritize clear architecture, readable Git repository, and concise deployment documentation for easy self-updating. I address the challenge of integrating AI models seamlessly within a modern server stack (e.g., Node.js, Python + FastAPI, Go) with potential microservices or serverless integration. I will deliver a full cycle: UX/UI design, development, testing, publishing preparation, and initial deployment support. Let's discuss the details via chat. Regards,
