Developer Needed to Build a Multi-App Aggregator Platform Using Official APIs (Only Pakistani)

We are looking for an experienced developer, preferably based in Pakistan, to develop an application that connects with multiple existing apps and services through their official APIs. The goal is to build a centralized aggregator platform where users can securely log in, connect their accounts from supported third-party applications, and access relevant information from those services in one place. # Key Features & Requirements - Third-Party App Integrations: Connect multiple existing applications and services using their official APIs. - Secure Account Login: Allow users to authenticate and connect their accounts using supported OAuth 2.0 or other official authentication methods. - **Data Aggregation: Fetch, organize, and display information from different connected apps within one unified dashboard. - API Integration: Work with REST APIs, GraphQL APIs, webhooks, and other supported integration methods. - User Dashboard: Provide a clean interface for viewing and managing connected apps, retrieved information, and account settings. - Secure Data Handling: Implement secure token storage, access permissions, encryption where appropriate, and proper authentication practices. - Error Handling: Handle API rate limits, expired tokens, failed connections, and unavailable services gracefully. - Scalable Architecture: Design the application so additional third-party integrations can be added in the future. # Required Experience The ideal developer should have practical experience with: - Building web applications or mobile applications. - Integrating multiple third-party APIs. - OAuth 2.0, API authentication, and authorization. - Backend development using Node.js, Python, PHP, or a comparable technology. - Database design and secure user-data management. - Frontend development and dashboard interfaces. - API documentation, testing, and debugging. # Project Scope The initial phase will focus on developing an MVP with a defined set of third-party integrations. The exact applications, data fields, and features will be discussed with the selected developer before implementation. All integrations must use legitimate, authorized access methods. The developer should identify available APIs, authentication requirements, access limitations, and any required platform approvals before starting each integration. We do not want unauthorized access, password collection for third-party accounts, or unapproved scraping as a substitute for official APIs. ### What to Include in Your Proposal Please share: 1. Relevant projects involving API integrations or aggregator platforms. 2. Your preferred technology stack and proposed architecture. 3. Examples of third-party services you have integrated. 4. An estimated timeline and budget for the MVP. 5. Any technical limitations or API access requirements you anticipate. We are looking for a developer who can help us build a secure, reliable, and extensible platform, with the possibility of ongoing development work after the MVP. Note: Please apply only if you have hands-on experience integrating multiple third-party services through their APIs.
