Build Specific Backend & Frontend Module
Budget: $250 – $750 USD
ImmigrateSmart is an existing immigration-tech platform designed to deliver structured, attorney-built immigration tools and workflows.
This engagement is not a greenfield build and not a long-term role.
You will be responsible for implementing clearly defined modules within an existing architecture, delivering working code, documentation, and handoff—then exiting cleanly.
Scope of Work (What you WILL do)
You will implement specific, pre-defined components, which may include some or all of the following (exact tasks will be milestone-scoped before start):
Backend (FastAPI / Python)
Build or extend API endpoints
Implement request/response schemas (Pydantic)
Integrate with third-party services (e.g. Stripe, email, calendar, webhooks)
Ensure modular, clean, readable architecture
Write basic validation and error handling
Frontend (React or Next.js)
Implement UI screens based on provided wireframes or descriptions
Connect frontend components to existing APIs
Ensure responsive, professional UX
No experimental UI frameworks unless approved
System Expectations
Code must be production-ready
No hardcoded credentials
Clear separation of concerns
No bloated dependencies
No “magic” logic without comments
What you will NOT do (Important)
You will NOT redesign the platform architecture
You will NOT act as product manager
You will NOT make unilateral tech stack changes
You will NOT control deployment environments
You will NOT remain on the project after final handoff unless a new contract is issued
Deliverables (Non-Negotiable)
Each milestone must include all of the following to be considered complete:
Working Source Code
Code must be delivered via the designated source-code repository (GitHub or GitLab).
Code must run locally or in a standard development environment as documented.
No hard-coded credentials, secrets, or environment-specific assumptions.
Repository-Based Delivery Only
The freelancer will be provided access only to the source-code repository.
No access will be granted to AWS, cloud consoles, production environments, or infrastructure credentials.
Deployment, hosting, and infrastructure configuration are handled internally.
Clear Documentation
A concise README or documentation file explaining:
what was built
how it works
how to run or test it locally
how it can be extended or modified
Documentation must be sufficient for another developer to continue without assistance.
Validation & Testing Confirmation
Basic validation that the feature works as intended (manual test steps or automated tests, as appropriate).
Any assumptions or limitations must be explicitly documented.
Clean Handoff
Code must be readable, commented where necessary, and organized logically.
No unfinished stubs, hidden dependencies, or undocumented behavior.
A milestone is not complete until the handoff is clean and documented.
