Build MVP SaaS Platform – Secure Document Delivery with Revocable Access

@raphaelokekeze

Building a secure document delivery platform requires a solid grasp of access control and data integrity. Your requirement for revocable access suggests a need for a robust backend architecture that handles user permissions and file lifecycle management effectively. With over 15 years of experience in PHP and MySQL, I have built numerous custom web applications that prioritize security and user-specific access. I am well-versed in creating secure document handling workflows and can ensure the system is both functional and resilient against unauthorized access. I can complete this MVP within your requested timeframe for a total of $434.25. If you are ready to move forward, let me know the specific authentication or file storage requirements you have in mind so we can get started today.

Hi, I propose to build a lean MVP SaaS web application for secure document delivery. Users can upload documents, send secure links, revoke access, and set expiry controls. The platform will have user accounts, file upload system, secure link generation, recipient view page, revoke access feature, expiry controls, sender dashboard, email notifications, and deployment. Let's discuss further. Regards, Sai Bhaskar

Hi There !! After reading your request, I found it to be rather intriguing. I can provide timely, high-quality assistance for your project as a senior full stack engineer. I have 10+ years of experience building SaaS platforms with secure file handling, authentication systems, and scalable cloud architectures. Your MVP is clear and well-scoped, and I can deliver it as a lean, production-ready system focused strictly on secure document sharing with revoke/expiry control. I will build a clean SaaS-style UI (login, dashboard, upload flow, send flow, recipient page) with a secure token-based sharing system. Each document will generate a unique signed URL with expiry and revocation controls enforced at API level. Revoke/expiry will immediately invalidate access. Dashboard will track status (sent/viewed/revoked/expired) with basic analytics. All files will be stored securely in S3 with pre-signed access links only. Let's talk further when we speak over the phone or chat. Awaiting for your positive response. Thanks

Hi, the project to build a secure document delivery MVP with revocable access aligns with core SaaS platform challenges around secure file sharing and access control. The real engineering risk centers on orchestrating immediate and reliable revocation of access tokens and managing secure link expiry without degrading user experience or system performance. I usually design systems by separating ingestion, storage, and access control layers to isolate responsibilities and simplify security enforcement. This approach supports rapid invalidation of tokens and scalable file delivery. My experience on Custom Feature Development & Integration involved enhancing SaaS products with secure, maintainable backend and frontend features, while the AI-Driven Marketing Suite project demonstrates building dashboards and notification flows relevant to your sender dashboard and email needs. I recommend implementing token revocation with cache invalidation patterns and audit logging for traceability, ensuring the system is production-ready yet lean for MVP validation. I can outline the secure link generation and revocation pipeline, map sender dashboard flows, and review file upload and access control strategies to ensure a robust MVP. Thanks, Hercules

Revocable access on delivered documents usually requires signed URLs with short TTLs rather than standard authentication flows. That distinction changes how you structure the storage layer and the delivery pipeline. I've architected SaaS platforms handling sensitive data before, including a video streaming service adopted by AACTA and a fintech platform with strict security requirements. The focus there was ensuring access control lived at the infrastructure level, not just the application layer. For an MVP in this budget range, keeping the stack lean is critical. I typically use Go or Node.js for the backend logic paired with secure S3 bucket policies for the actual document storage. This avoids over-engineering while keeping security tight. Are you planning to handle user authentication separately or do you need that built into this scope as well?

@BarryCrouch

​I have two quick questions to help me get started: ​Since we want the recipient view to look professional for finance and legal users, do you have a specific logo or color scheme you'd like me to incorporate into the design? ​To keep the dashboard simple for you to manage, would you prefer the "view count" to be a simple number, or should we show a small list of when each view happened? I'm ready to kick this off immediately and can provide a detailed timeline once we chat. Are you free for a quick message to discuss the next steps? ​Best regards,

@Lincolnwhiz

One aspect that sets me apart is my focus on not just delivering a functional backend, but also developing clean, modern, and professional frontend interfaces. I believe a good UI/UX implementation is essential to ensure users have a seamless experience while using the platform – across functionalities like login page, dashboard, file upload/send flow screens & recipient view/revoke/expiry controls UIs. Finally, I’m able to work independently towards project goals without relying on constant management guidance and my approach relies on building scalable solutions that grow with your business. So, if you choose to work with me, expect not just a deployment-ready MVP but also clear communication throughout the project, reliable delivery within realistic timelines and a long-term mindset aimed at future-proofing your solution. Let's connect to discuss further how we can turn your vision into reality.

@amjad2

Hello, Could you clarify if you prefer a specific user interface design for the MVP, or should I focus on a clean and modern aesthetic? I can build a secure document delivery platform that allows for uploads, link sharing, and revocation of access—all core functionalities you’ve highlighted. To ensure alignment, I’d like to ask a few questions: 1) Do you have a preferred authentication method (email/password or magic link)? 2) Are there specific file types and size limits you want to enforce? 3) What kind of analytics metrics are essential for the sender dashboard? 4) Any third-party email API preference for notifications? 5) How would you like to handle the expiry settings (after X days or after first view)? The cost and timeline will be placeholders until I discuss these details further. I have extensive experience building SaaS applications and am well-versed in your preferred tech stack. Looking forward to your response! Relevant Portfolio: • https://www.freelancer.com/u/amjad2 Best Regards, Amjad Iqbal
