MongoDB Jobs

I’m launching a medium-scale online store that serves customers exclusively within my city. The site will sell physical goods only, so the buying journey must feel fast and friction-free from browsing to doorstep delivery. Core functionality I need you to put in place for this MVP: secure user registration/login, full product catalogue and cart flow, a checkout that accepts credit/debit cards, popular digital wallets, UPI, and a fallback Cash-on-Delivery option, plus separate dashboards for Administrators, Vendors, and Customers. I’m flexible on the tech stack—Laravel, Django, or a modern JavaScript framework such as React with Node/Mongo are all fine so long as the code is clean, well-documented, and scalable for future city-wide growth (think flash-sale traffic sp...

You will join our product team full-time to design, build, and maintain a real-time web application powered by Node.js and React. On the backend you’ll craft well-structured JavaScript services, optimise algorithms and data structures for speed, and handle event-driven flows with sockets, Redis, and WebRTC. On the frontend you’ll ship responsive React interfaces that consume those services smoothly. Our data layer runs on MongoDB, so you’ll model documents, tune queries, and manage indexing for performance and scale. Day to day you’ll touch every layer of the stack—from server-side architecture and deployment scripts to pixel-perfect components—so broad curiosity and independent problem-solving are essential. Core expectations • Deep JavaScript ...

I have a MERN social media app with a Quill-based rich-text editor. Images take over 1 minute to appear inside the Quill editor on the FIRST upload, but all uploads after that appear instantly. I need a React/MERN expert to fix this behavior — or replace Quill with a better editor without breaking any existing UI or functionality. What I Need Option A: Fix Quill and Google Sign-in Functionality & Delays First image upload must appear instantly (≤1 sec). Subsequent uploads already work — don’t break them. Google Sign-in must load fast and log users in successfully blazingly fast. OR Option B: Replace Quill Google Sign-in must load fast and log users in successfully blazingly fast. Use TipTap / Lexical / TinyMCE / Slate only if: Looks and behaves the same or...

My MongoDB Atlas cluster connects instantly through Compass, yet the same connection string refuses to cooperate inside my React project. The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

I am building Meet-sphere, a browser-based video calling platform geared toward friends and family. You can preview the current proof-of-concept here: The core is already in place—ReactJS on the front end, an Express/NodeJS API backed by MongoDB, and peer connections over WebRTC managed through with token-based authentication. I now want to move from demo to production quality by adding: • Screen sharing that works smoothly on Chrome, Firefox, and Safari • Multi-user conferences (3–6 participants in a room without noticeable lag) • An integrated text chat pane, delivered over the existing socket layer and persisted to MongoDB for reloads The codebase is modern React (hooks, Context, Vite), and the server runs on Express with JWT auth. You’ll have...

Hi, I’m looking for an expert who can help me replace my current Firebase backend with MongoDB on my server. The migration involves about 2 GB of data and there are around 10 collections such as products, categories, pages, etc. I need to keep a similar structure so it continues to work with the existing project. The website is currently working perfectly and I want it to continue working the same way after the replacement without breaking anything. Thank you.

I want to give my Discord community a full-blown cricket experience: members draft their own teams, play head-to-head fixtures, and climb seasonal leaderboards while earning an in-game currency they can spend on transfers or upgrades. Here’s the gameplay scope I have in mind. The bot must let users create and manage squads, then simulate matches in T20, ODI (One Day) and Test formats. At launch I need three game modes—PvP challenges, knockout tournaments and long-form leagues—with the architecture left open so we can bolt on extra modes later. Each fixture should run ball-by-ball logic, generate realistic scorecards, update individual player statistics automatically, and broadcast concise commentary to match channels. An in-server economy underpins everything: every...

I maintain several large, structured datasets spread across MySQL, PostgreSQL and SQL Server instances. Only portions of the existing schemas are documented, so the very first step will be to inspect each system, reverse-engineer any missing metadata and confirm table relationships. Once the landscape is clear I need all records extracted, cleaned, normalised and deduplicated, then merged into a single, well-organised MongoDB database. Your work should include a carefully planned document model that supports growth, fast look-ups and straightforward analytics. Proper indexing, sharding strategy (where appropriate) and query optimisation are critical because future workloads will be heavy and latency-sensitive. Please deliver: • An optimised MongoDB schema and architecture diag...

My container is deployed on Cloud Run and attached to a VPC via a Serverless VPC Access connector that in turn goes through Cloud NAT with a public IP. A custom domain is mapped as well. Despite the setup, the service cannot reach the public internet—most visibly the MongoDB Atlas cluster. I have already reviewed firewall rules, confirmed the NAT configuration, and inspected container logs, yet outbound traffic still fails (other external endpoints time-out too). What I need from you • Pinpoint the exact root cause of the egress blockage—routing, connector, IAM, or anything else—so I understand why it broke. • Apply the fix live during a screen-sharing session; no code transfer will be necessary. • Prove success by showing my backend log line that ...
