SaaS Enterprise Dev: Web Platform & iPhone App

Experienced Developer/Team Wanted — Web Platform + iPhone App (Saudi B2B Project)
I’m looking for a skilled developer or development team to build an enterprise-grade B2B SaaS platform targeting the Saudi market, consisting of a full web platform and an iPhone application.
About the project (high level):
A digital platform connecting businesses with specialized service providers, featuring multi-role dashboards, secure document management, and intelligent data processing. Full details will be shared only after signing an NDA.
General technical requirements:
• Full-stack web development with responsive design supporting Arabic & English (RTL/LTR)
• High-quality native or hybrid iOS application
• Multi-level user registration and role-based access control with SMS OTP verification
• Secure, encrypted document upload and management
• Experience integrating AI APIs is a strong plus
• Hosting within Saudi Arabia and compliance with local data protection standards (PDPL)
What to include in your proposal:
1. A brief on your experience and similar projects you’ve delivered (portfolio links)
2. The tech stack you recommend and why
3. A rough timeline estimate and your delivery approach (milestones)
4. Whether you work solo or with a team
Notes:
• Priority given to those with SaaS or multi-sided platform experience
• An NDA will be signed before any project details are shared
• The project is phased; we’ll start with an MVP
