About the role

We’re looking for a curious, hands-on Junior Full-Stack Developer to help us build features end-to-end in a modern JavaScript/TypeScript stack. This is a part-time, fully remote role—ideal if you’re looking to grow your skills while contributing to production work.

What you’ll do

Implement user interfaces with React and Next.js (SSR/SSG, routing, forms, state management).
Build and maintain backend endpoints in Node.js / Next.js API routes.
Design and query MongoDB databases; model data with Mongoose (schemas, validation, indexing).
Contribute to server architecture and database architecture decisions for reliability, performance, and security.
Integrate third-party REST/GraphQL APIs (auth, rate limits, pagination, error handling).
Work with AI model APIs (e.g., Claude “Sonnet” 4.5 or similar) for tasks like summarization, classification, and agent-style workflows.
Write clear, maintainable code with TypeScript types; add tests and documentation.
Collaborate via GitHub (PRs, reviews, issues) and communicate progress in short async updates.

Must-have qualifications

1+ year of experience (commercial or strong personal projects) with React and Next.js.
Solid TypeScript and JavaScript fundamentals.
Practical experience with MongoDB and Mongoose (schema design, relationships, indexes).
Understanding of server fundamentals (HTTP, auth, caching) and basic DB architecture concepts (normalization vs. denormalization, query optimization).
Experience consuming and integrating external APIs; familiarity with OAuth/JWT.
Comfortable working remotely and part-time, managing your own time and communicating clearly.

Nice to have

Node.js performance profiling and observability (logs, metrics).
Testing frameworks (Jest, Vitest, Playwright) and API testing with Postman/Insomnia.
Basic DevOps: env management, Docker, CI/CD.
Experience with additional AI providers (e.g., OpenAI, Google, etc.) and prompt/response design.
UI polish: accessibility, responsive layouts, component libraries.

Tools we use

Next.js, React, TypeScript, Node.js
MongoDB, Mongoose
REST/GraphQL, Webhooks
Git/GitHub, issue tracking, lightweight documentation

Working arrangement

Part-time only (hours flexible; agree on a weekly target).
Fully remote with async communication; occasional real-time check-ins as needed.
Deliver in small, testable increments; proactive status updates.

How to apply

Send your CV, a short note about your availability (weekly hours), and 2–3 project links (GitHub or live demos) showcasing relevant work in Next.js/React/TypeScript and MongoDB/Mongoose. If you’ve integrated any AI model APIs, include a brief description of what you built.
