Cross-Platform App Architecture Build
Budget: $3,000 – $5,000 USD
This is a green-field initiative: a single application that must operate seamlessly across web, desktop and mobile. The work begins with a clean sheet of paper and ends with a production-ready release.
Scope
• Shape the high-level architecture—data models, service boundaries, scalability, security and deployment strategy.
• Select and justify the tech stack (e.g., React, Vue, Angular, Flutter, Electron, Node, .NET, Go, or another combination you have proven in production).
• Implement the entire solution: front-end UI, back-end APIs, database schema, automated tests and CI/CD pipeline.
• Deliver code that is clean, documented and ready for hand-over.
Deliverables
1. Architecture blueprint (diagram + written rationale).
2. Source code for web, desktop and mobile builds.
3. Deployment scripts/pipeline configuration.
4. Developer-level documentation.
How to apply
Experience speaks loudest here. Highlight a few past projects where you shipped production-grade software on multiple platforms and outline the key architectural decisions you made.
Acceptance criteria
• Builds run without errors on the agreed platforms.
• Automated test suite passes.
• Documentation allows another engineer to spin up the environment and deploy in one sitting.
If designing and building robust cross-platform systems from scratch is second nature to you, this project is the perfect fit.
