NoSQL Couch 和 Mongo Jobs

I’m ready to establish a solid digital presence that connects seamlessly with our internal computer system. The public-facing part will be a clean, responsive website that introduces the company and channels visitors toward contact or service pages. Behind the scenes, I need a robust data-management backbone dedicated to secure storage. Here’s what the system must do: • Data management and storage that scales as we grow • Automated backups running on a schedule I can adjust easily • Built-in data analytics tools so I can pull trends and reports without exporting spreadsheets • Granular user-access controls that let me decide who can view, edit, or delete each data set You’re free to suggest the stack, but reliability and maintainability are cr...

My existing n8n automations work, but they feel sluggish and occasionally force me to wait longer than they should. I need an n8n specialist who can improve our current workflows with a clear focus on boosting overall efficiency and speed. You’ll start by reviewing the live flows, profiling each node, and pinpointing where the execution pipeline loses time—whether that’s a poorly-placed wait node, unnecessary loops, or sub-optimal API calls. Once the bottlenecks are clear, I’ll rely on you to refactor the logic, tune concurrency and resource settings, and document the changes so the gains are measurable and repeatable. Deliverables • A brief audit report outlining the key slow points and the optimisation strategy • Updated, fully tested workflow JS...

I’m looking for a full-time front-end engineer based in Gujarat who can own everything we do in React.js and Next.js. You’ll be the point person for new feature work, performance tuning, and day-to-day maintenance of our customer-facing web app. Our backend stack runs on Django with Supabase and Postgres, so you’ll spend most of your time in React/Next but also collaborate closely with the Python team and consume their REST and GraphQL endpoints. Key points • Location: must already be in Gujarat (we meet once a month in Ahmedabad) • Experience: 3+ years building production React applications • Schedule: full-time, 8 hrs a day, Monday–Friday, long-term Your routine will involve: – Shipping well-tested React and Next components &nda...

I’m building a ticket-based travel platform and need an experienced NestJS/Node.js developer to own the entire backend. The core of the job is to design and code a robust booking engine, connect it to external services, and expose clean, well-documented REST/GraphQL endpoints for the web and mobile apps that will sit on top. What has to plug in • Payment gateways, travel service providers, and user authentication services all need first-class, fault-tolerant integrations. I already have partner documentation for each service; your job is to wire them up, handle retries/timeouts, and log everything clearly. Booking workflow The platform must perform Real-time availability check before every purchase, send Booking confirmation notifications (email + optional SMS), and support fu...

I need help getting a Node.js-based web app that also exposes an API up and running in my Azure environment. The code is ready; what’s missing is a clean, repeatable deployment that points to our SQLite database and respects the usual production basics—environment variables, HTTPS, logging, and autoscale settings. You’ll work directly in our Azure subscription, set up any required App Service (or container workflow if that proves simpler), wire up the build/release pipeline, and verify the application is reachable from the web as well as through its REST endpoints. I’ll provide repository access and current config files at kickoff; you make the necessary Azure adjustments, push the app live, and document every step so I can reproduce it later or roll back confident...

My VIBE-built front-end for a student learning and testing platform is already in place; what’s left is a lean, well-structured back-end so the entire MERN stack can go live. I need you to spin up a Node.js/Express service, wire it to MongoDB, and expose the endpoints required by the existing React code. Here’s what the back-end must cover: • User authentication (JWT or comparable session strategy) • Core database models and queries in MongoDB, using Mongoose • RESTful routes that the current UI already expects • Integration points for three APIs: a payment gateway, an external data source, and a notification service (web-push / email) Acceptance criteria • Every front-end call returns the correct payload or error code. • Users can ...

I need a developer who can build a mobile-first, browser-based application that lets users organise their schedules, log tasks, and track work vs. break time from a clean, intuitive interface. The core of the tool is a calendar that supports simple colour-coded events; beyond that, I want a straightforward task list, a running timer for each task, and automatic push notifications so users never miss an upcoming block of work or a scheduled pause. Because the app must feel seamless on mobile browsers, responsive design and lightweight front-end performance are essential. I’m happy for you to choose the stack—React, Vue, Svelte, or something comparable—as long as it remains maintainable and easy to extend. A modest back end (Node, Firebase, Supabase, etc.) can store user d...

I already have the front-end of an e-commerce site in place; what I’m missing is a robust, well-structured backend written in Node.js with Express and MongoDB. The API must cover three core areas: • User authentication – Secure sign-up / login endpoints, JWT session handling, password hashing, and role-based access control strictly for Admin and Customer accounts. • Product management – Endpoints to add, edit, delete products, assign categories, and adjust inventory quantities automatically after each purchase. Data should be modelled cleanly in MongoDB with appropriate indexes to keep queries fast, especially on category and stock-level fields. • Order processing – Create, read, update order flows that tie into inventory deductions, re...

I’m building a personal web & mobile application and now need a skilled graphic designer to shape its entire visual identity. Although the coding is handled elsewhere, the app still lacks polished, platform-ready artwork. Here’s what I’m after: cohesive UI visuals, icons, splash screens, and any other graphic elements the app requires to look first-class on both iOS and Android devices. Because the same core design will serve two platforms, assets must respect each store’s sizing, resolution, and safe-area guidelines while maintaining a single recognisable style. You’ll receive wireframes and a short mood-board as creative direction. From there, I expect layered source files (Figma, Sketch, or Adobe XD), plus exported PNG/SVG sets ready for Xcode and A...

A new AI–powered web application is underway and the immediate priority is a robust, well-architected backend. I already have high-level product requirements and some early frontend prototypes; what’s missing is the server-side logic that will tie everything together, expose clean REST/GraphQL APIs, and host the machine-learning models that drive the core features. Your role centres on backend development. I’m flexible on language and framework—Node.js, Django/Flask, or Spring Boot are all on the table—so long as the final stack is scalable, well-tested, and easy for other engineers to extend. Cloud deployment (AWS or GCP), containerisation (Docker), CI/CD and security best practices should feel second nature to you. Deliverables • Design and implemen...

I have a complete UI/UX for both a web app and its companion mobile build in React Native. What I’m missing is the working engine behind the screens. Here’s where I am: • Front-end screens and flows are finished and ready for data. • No backend currently exists and there’s no database yet—everything will need to be architected from scratch. • I’m flexible on database technology and service architecture, so please suggest what you believe will scale well and keep the codebase clean. What I’d like you to deliver: 1. Design and implement a secure, well-documented backend (Node.js, Express, Django, or equivalent—open to your recommendation). 2. Create the database schema, migrations, and seed data, then connect it to the API laye...

I’m building Curacare, a full-stack web app that lets people handle medical emergencies without scrambling for information. The heart of the platform is a seamless doctor-consultation flow, so the appointment-scheduling module has to feel effortless on both mobile and desktop. Alongside that core feature, users must be able to reach hospitals instantly through a dedicated “Contact Hospital” pathway—click-to-call, email, or any direct channel you suggest—surfaced within one tap from the dashboard. Speed and reliability matter more than bells and whistles: every interaction should load in under a second, and every piece of patient data must be encrypted at rest and in transit. Tech-stack choices are open, though I’m leaning toward a React front-end, ...

I’m expanding our engineering capacity and need a hands-on Sr. Full-Stack Developer who can own technical delivery end-to-end with Node.js on the server and React.js on the client. You’ll be writing production code every day while steering architecture, guiding estimates with our Project Manager, and mentoring two to four mid-level engineers. Most of our roadmap centres on customer-facing web applications with companion mobile builds, so you should feel equally comfortable shaping REST/GraphQL back-ends, crafting responsive React components, and reviewing pull requests for performance, security, and scalability. Continuous deployment lives in GitHub Actions; infrastructure runs on AWS, so practical experience there is a plus. This is a full-time, individual-contributor po...
