Budget: 20000 UAH Deadline: 45 days
Hello!
I have reviewed the project description — the requirements are clear, logical, and well-structured. This is a full-fledged digital product marketplace with scaling potential, and I have relevant experience for its implementation.
Relevant experience
Development of SaaS platforms and web services with roles (user / admin / seller)
Implementation of API-first architecture
Working with digital products (files, accesses, automatic issuance)
Integrations of payment systems, file protection, action logging
Scalable backend solutions and clean frontend
Proposed technical approach
Backend: Node.js (NestJS) or Django — depending on the load and business logic
Frontend: Next.js (SEO-friendly, fast rendering)
DB: PostgreSQL
Files: Cloud storage (S3-compatible) with temporary signed URLs
Architecture: API-first, ready for scaling and integrations
Security: isolated access to files, tokens, action logging, protection against re-uploads
In stages
Analysis and architecture
UX/UI prototyping
Development of MVP
Testing
Deployment + documentation
Estimated assessment
Timeline: 45–60 days (MVP)
Budget: I suggest discussing after clarifying the scope of the MVP and payment logic
I can additionally offer
Separation of MVP / Full version for budget optimization
Preparation of architecture for future subscriptions and API partnerships
Automation of payments to sellers
Sales analytics and user behavior
I am ready to discuss the details, propose an optimal MVP, and proceed through a safe process with transparent communication.
