Title: T-CPT-10747 Front-End Developer (React) Virtual Assistant
Independent Contractor – T-CPT-10747 Front-End Developer (React) Virtual Assistant/Technical Support/Entry-Advanced Level (Remote).
Overview
20four7VA is seeking offshore independent contractors to deliver remote services to clients worldwide, with a primary focus on developed markets such as the United States, the United Kingdom, Canada, and Australia.
Client is seeking a mid-level Front-End Developer Virtual Assistant with strong React experience to support development of its proprietary permit automation platform. The platform is a feature-rich SaaS application built with React 18, Redux Toolkit, and Material UI, handling complex workflows including permit form processing, real-time updates, payments, and GIS/mapping. The developer will work on improving and expanding the front-end interface to support permit technicians, clients, and internal teams. The candidate will report directly to the lead developer.
Note: This is not a junior-friendly codebase. We are looking for a minimum mid-level candidate who is comfortable working within a large, existing production codebase from day one.
The objective of each engagement is to assist the client in improving business efficiency, enhancing service delivery, or supporting operational functions through high-quality, task-specific services rendered by a qualified contractor.
Scope of Services
Contractors will be required to provide services that align with the following client tasks:
Front-End Development
Develop and maintain front-end features using React 18 (functional components, hooks)
Build and improve UI components using Material UI v6 including MUI X (DataGrid, DatePickers)
Implement new features from clearly defined Linear tickets with acceptance criteria
Work within Redux Toolkit architecture (slices, async thunks, selectors)
Maintain and extend WebSocket-based real-time features
Manage complex routing with React Router v6 (guarded routes, multi-role layouts)
Platform Support & QA
Conduct regression testing on new features before staging deployment
Work closely with the lead developer to understand API contracts and backend responses
Debug and resolve UI performance issues (memoization, render optimization)
Maintain clean, well-documented, readable code
Permit Forms & Product Work
Build and maintain permit form templates within the platform (building permits, electrical permits, NOCs, legal descriptions, and other municipal/legal documents)
Support the forms digitalization pipeline (AI-assisted PDF form processing)
Provide recommendations for improving usability and workflow efficiency
Technical Debt & Migrations (when feature work is quiet)
Assist with incremental migration from JavaScript to TypeScript
Assist with migration from Create React App (CRA) to Vite
These are well-defined tasks that will be assigned via Linear tickets
Each engagement is based on a defined scope of work and is governed by an independent contractor agreement. Services must be performed professionally, with adherence to any timelines, guidelines, and deliverables agreed upon in writing.
