Job Description

Fullstack Developer – React & Node.js

Onsite | Dhumbarahi, Kathmandu

Project Overview

We are building a modern web portal that serves as a gaming and user interaction platform. The first version includes user authentication, game upload and playback (ZIP → playable format), configuration settings, and full user activity analytics. The developer will be responsible for building or continuing development on this portal with a strong focus on performance, scalability, and clean code structure.

As the platform evolves, it will expand to support new game formats (e.g. Unity WebGL), multi-language support, payments, advanced filtering, and broader analytics. The ideal candidate must be able to deliver now and scale for the future.

Core Responsibilities

User System & Authentication

Build a secure registration and login system using both email and SMS authentication (OTP, password, or passwordless flows)
Encrypt passwords using best practices (e.g., bcrypt or Argon2)
Manage JWT or secure session-based authentication
Handle user roles and access control (admin, standard user, etc.)
Create a smooth, multi-step registration funnel Game Upload & Playback
Support ZIP-based game uploads via admin interface
Extract and render games in a playable, embeddable format (HTML5/JavaScript games initially)
Implement error handling, preview support, file validation, and safe sandboxing

Dashboard, Logs & Analytics

Track and log all user actions: signups, logins, uploads, gameplay events, config changes
Build backend analytics endpoints to support:
Funnels and drop-off tracking
Game usage metrics
Daily/monthly active users
Engagement heatmaps and filters
Date comparisons and trend analysis
Build frontend dashboards (charts, filters, breakdowns) using charting libraries like Recharts or Chart.js

Filtering & Admin Tools

Implement dynamic filtering (e.g., by date, region, status, game type)
Build server-side paginated endpoints for filtering large datasets
Enable CSV or JSON data exports
Provide an admin panel for managing users, games, and settings Configuration & Messaging
Create a config system for platform-wide messages (e.g., admin pop-ups, alerts)
Enable dynamic updates without code changes

Future Requirements (Scalability-Ready)

Internationalization (multi-language frontend with i18n)
Payments integration (Stripe, in-app wallets, transaction logs)
Expansion to support Unity WebGL and mobile games (future format handling)
Social logins (Google, Apple, Facebook)
2FA, admin impersonation, or audit logs
Advanced analytics export or integration with PostHog, Segment, or custombuilt solutions

Technical Requirements Frontend (React)

Strong experience with React Hooks and modern frontend architecture
Familiar with TailwindCSS, shadcn/ui, or similar modern UI systems
Able to build responsive, component-driven UIs and dashboards
Comfortable handling complex UI states, filters, and real-time data presentation

Backend (Node.js + Express or NestJS)

Experience building REST APIs with scalable folder structures (MVC or servicebased)
Proficient in authentication, middleware, logging, rate limiting, and file handling
Comfortable building complex business logic, backend validation, and logging systems
Able to handle file uploads, zip extraction, background processing (e.g., queues if needed)

Database (PostgreSQL or MongoDB)

Experience designing normalized schemas or document structures
Capable of writing efficient queries (joins, aggregations, filters)
Familiar with indexes, migrations, performance tuning
Comfortable handling analytics queries at scale

DevOps & Hosting

Experience deploying apps using Vercel, Netlify, AWS, DigitalOcean, or similar platforms
Knows how to manage .env variables, SSL, CORS, health checks
Familiar with CI/CD pipelines and basic monitoring/logging setup (e.g., Sentry, self-built dashboards)

Candidate Profile

We are looking for a hands-on fullstack developer who:

Has 4+ years of fullstack experience (React + Node)
Has built real-world portals or platforms (not just landing pages or small apps)
Understands how to build scalable products from the ground up
Writes clean, modular, maintainable code with proper documentation
Communicates clearly and works independently
Can break vague specs into concrete, executable features
Thinks ahead: builds now with tomorrow’s scale in mind

Nice to Have
