Node Microapps Developer for Cloudflare Deployment
Upwork • , US • Remote
Posted on: 11th March, 2025
Employment Type: CONTRACTOR
Job Description
Project Overview
We are seeking a skilled developer to help finalize and deploy a series of specialized microapplications that integrate with our Cirrus File Server (CFS) platform. These microapps are small, single-function applications that are launched from within CFS to perform specific document processing operations and will be deployed on Cloudflare's platform (Pages and Workers).
The core framework and code for these applications is initially created using AI assistance (Claude or GPT), and we need a developer to finalize, refine, and deploy the applications to our Cloudflare sub-account. This is approximately an 80/20 distribution of work, with AI handling 80% of the initial development.
Required Skills & Experience
Strong experience with JavaScript/TypeScript development
Proficient in React.js for frontend development
Experience with Cloudflare Pages and Cloudflare Workers
Familiarity with OAuth 2.0 implementation and token management
Experience with REST API integration and proxy services
Knowledge of serverless architecture and edge computing
Experience with file processing and handling (PDFs, Word documents, etc.)
Strong understanding of security best practices for web applications
Ability to review AI-generated code for security and performance issues
Preferred Skills
Experience with Wrangler CLI and Cloudflare deployment workflows
Knowledge of document processing libraries (PDF.js, mammoth.js, etc.)
Previous work with OAuth server integration
Experience adapting Express.js code to Cloudflare Workers
Experience with AI-assisted development workflows
Understanding of CORS and cookie management in multi-domain environments
Responsibilities
Review and refine AI-generated code for CFS Microapps
Adapt Express-based proxy code to Cloudflare Workers environment
Implement missing functionality and fix any issues
Enhance security, error handling, and edge cases for serverless deployment
Configure proper CORS and authentication flows in a Cloudflare environment
Optimize performance for edge computing
Document code and processes for future maintenance
Deploy applications to our Cloudflare sub-account (credentials will be provided)
Provide expertise on best practices for Cloudflare Workers and Pages
Project Details
Each microapp follows a standardized pattern but is adapted for Cloudflare's serverless architecture:
A Cloudflare Worker that handles authentication with CFS via OAuth and proxies API requests
React-based frontend deployed on Cloudflare Pages
API integration with CFS for document retrieval and storage
Specific document processing functionality unique to each microapp
The first microapp is a Document Anonymizer that processes PDF and Word documents from CFS, anonymizes them, and saves them back to CFS. All microapps will be deployed to a dedicated Cloudflare sub-account with limited permission access.
Required Availability
This is a project-based position with an estimated 20-40 hours per microapp
Regular communication during development (2-3 times per week)
Ability to meet deadlines for each microapp (typically 2-3 weeks per project)
To Apply
Please include:
Your experience with Node.js, React, and OAuth implementation
Examples of similar integration projects you've worked on
Your approach to code review and enhancement of AI-generated code
Your availability during the next 3 months
