Express JS Jobs

My team needs a seasoned full-stack developer to step in as a consultant who can transfer knowledge rather than write code. I’m specifically looking for someone confident across frontend, backend, and database layers who can translate that depth into clear, structured technical training sessions. Your core mission is to design and deliver training that sharpens our developers’ practical skills. Expect to break down real project scenarios, walk through architectural decisions, explain code quality best practices, and answer ad-hoc questions as they come up. We work mostly with JavaScript/TypeScript, React, Node.js, and PostgreSQL, so fluency in these (or closely related stacks) will help you connect quickly with the team. Deliverables • A short training plan outlining top...

I’m searching for production-ready AI agents I can roll out across several verticals—specifically Healthcare, Real Estate, E-commerce, Blockchain, Crypto, and Social Media. Each solution must already be live somewhere so I can see it operating in real time before we move forward. The core requirements are straightforward: the agent needs to run in a browser, accept its own knowledge base or document set for context, and ship with source code plus clear documentation. I’m also expecting help getting the code stood up in a SaaS or on-prem environment. I’m flexible on architecture; whether you built it around OpenAI, Claude, Llama, FastAPI, Node.js, Pinecone, FAISS, or Weaviate doesn’t matter as long as it performs reliably at scale. To keep things simple, here...

We are building a service marketplace mobile application (similar concept to UrbanClap / Ola / Uber for services) where users can book nearby service providers such as plumbers, electricians, cleaners, healthcare attendants, etc. We are looking for an experienced React Native App Developer / Team who can develop the complete mobile app ecosystem along with backend integration. Development of two separate mobile apps: User App Service Provider App With one centralized backend & admin panel. User App Features • User Registration & Login (OTP / Email) • Profile creation & management • Location detection (Auto + Manual) • Nearby service provider listing • Service booking system • Live service tracking (Map based) • In-app chat with provid...

I’m building a browser-based stock management platform and I’d like it developed with the classic MERN-style pairing of React (frontend) and Express with PostgreSQL (backend and database). The system will be accessed externally by both Suppliers and Customers, so clean, responsive UI components and a secure REST API are essential. Core scope The application must let us track inventory in real time, move orders through their full life-cycle, and surface clear reporting and analytics dashboards. Three permission tiers will exist—Admin, Manager, and Viewer—each seeing only the screens and actions appropriate to their role. Tech expectations React 18 with functional components and hooks, Express 4+, PostgreSQL 14+ with well-structured schemas, and JWT-based authen...

This project is a new social networking platform that needs end-to-end development on the MERN stack. The goal is to deliver a scalable, secure web application where users can create accounts, interact in real time and consume dynamic content. Core work spans the full stack: designing MongoDB collections, building an Express/Node.js backend with REST or GraphQL endpoints, and crafting a responsive React front-end. Real-time features (chat or live updates) should leverage or a comparable solution. Clean, well-commented code in a Git repository and deployment to a staging server are essential. Deliverables: • MVP deployed to a test server with sign-up/login and editable user profiles • Documented API plus a concise README for local setup • Two weeks of post-launch...

I need a sharp-eyed Flutter / Node.js troubleshooter to pinpoint and fix an intermittent signup failure in my mobile app. The OTP step completes successfully, yet many users (on both iOS and Android) hit a wall when the form tries to create the account. No explicit error is returned to the UI, but the account never appears in the database. Here is what I can share right away: • Front end: Flutter 3.x, using MSG91 for phone-based OTP. • Back end: Node.js (Express) REST API, MongoDB. • Flow: user enters phone → receives OTP → OTP verified → form posts profile details → failure occurs after the POST. What I need from you is a fast, reproducible diagnosis, a clean code fix (whether in Dart, the REST endpoint, or both), and a short hand-off note so my te...

The goal is to craft a complete web application from the ground up, pairing a React.js front end with a Node.js back end and shipping a functional MVP within a month. I already know I want React for the client interface, so the build should follow best-practice component architecture, modern hooks, and a clean, responsive layout. On the server side, Node.js (Express preferred) will power a RESTful API, handle authentication, and connect to a persistent data store—MongoDB or PostgreSQL, whichever you feel best suits the use case. To keep expectations crystal clear, here are the concrete deliverables: • Git repo initialized with meaningful commits, README, and .env sample • React UI coded, styled, and wired to the API (state management via hooks or Redux) • Node.js...

We need a Node.js Expert from Pakistan or India we need work for Guidance and Help we need work for long term

The core of my project is an API service already running on .NET 5 and paired with an Angular front-end. I need hands-on, task-based support to keep new features moving quickly while maintaining clean, testable code. Here’s the current stack and workflow so you know what you’ll be jumping into: • Backend: ASP.NET Core 5, Entity Framework Core, RESTful endpoints. • Front-end: Angular (latest stable), RxJS, Material. • DevOps: Git, pull-request reviews, CI builds on GitHub Actions. Typical tasks you could pick up include: • Expanding endpoints and DTOs. • Wiring new Angular components to the fresh endpoints. • Adding unit / integration tests where coverage is thin. • Fine-tuning performance or refactoring when technical debt appe...
