Full Stack Developer (React / Node.js) (Project True) Contract 11 Months

JobDescription

• Frontend: building responsive web applications with React — UI components, state management,

routing, and business logic, including web-based mini apps that run inside the super app's

WebView

• Backend: designing and building Node.js services — REST APIs, authentication/session

handling, database schema design, and integration with the platform's core services (points,

payments, user profile)

• Database work: schema design, query optimization, and migrations (PostgreSQL or similar)

• Writing and maintaining tests across the stack — unit, component, and API/integration tests

• Debugging issues across the full stack — browser/WebView rendering, API performance, and

database bottlenecks

Qualifications

• 3+ years of professional JavaScript/TypeScript development experience across frontend and

backend

• Strong React experience — component lifecycle, hooks, and modern patterns (feature-based

folder structures, separation of concerns), plus solid HTML/CSS fundamentals and responsive

design

• Experience with a state management solution such as Redux Toolkit, Zustand, or React

Query/TanStack Query

• Strong Node.js backend experience (Express or NestJS) — REST API design, authentication

flows (JWT, OAuth), middleware, and error handling

• Working knowledge of relational databases (PostgreSQL/MySQL): schema design, indexing, and

writing efficient queries

• Comfortable writing tests as part of normal development

• Strong debugging skills — able to work through build issues, API failures, and

cross-browser/WebView quirks independently across the stack
