My enterprise platform is already running on ReactJS in the front-end and Spring Boot in the back-end, yet the programming side of our internal operations still feels heavier than it should. I want to streamline the way new features move from idea to production, tighten the feedback loop between UI and APIs, and remove the little friction points that slow the team down today. You will work across the full stack: shaping clean React components, hardening Spring Boot services, refining our PostgreSQL queries, and wiring everything together with well-structured REST endpoints. Expect to touch build pipelines (Maven, Webpack), unit and integration tests, containerisation (Docker), and CI/CD scripts while you’re here—anything that helps us ship faster and with fewer surprises. Del...
I have purchased the “Shortie” CodeCanyon package, which ships with a Flutter mobile app (Android + iOS) and a Node.js + MongoDB backend. I already own a fresh VPS and the necessary source files; what I need now is an end-to-end deployment and polish so the platform is production-ready. Scope of work • Spin up the Node.js server, connect it to MongoDB, and deploy everything on my VPS (domain and SSL are already in place). • Compile and configure the Flutter apps, ensuring both Android and iOS builds run smoothly with Firebase and Apple/Google sign-in. • Enable the built-in “PK Battle” and “Gifting” modules and verify their real-time performance. • Refresh the UI/UX to match my brand guidelines, implement several small feature...

I need a seasoned MERN developer who can drop straight into a well-documented codebase, grasp the architecture quickly, and get critical production blockers out of the way without hand-holding. The immediate pain points are twofold: stubborn API failures that are breaking key user journeys and a cluster of UI bugs eroding the front-end experience. Alongside those fixes, I also need two high-impact features shipped fast—robust user authentication (JWT-based, social log-ins a plus) and real-time notifications pushed to the client via WebSockets or an equally reliable solution. You’ll be working with MongoDB, , React, and Node.js, so deep knowledge of that entire stack—as well as sharp debugging instincts, clean Git practices, and a knack for performance tuning—a...

I need an end-to-end solution that gives me real-time visibility over our public-facing assets and any related dark-web exposure. The work is split into two equally critical parts, so please scope your approach with that in mind: 1. ASM (Attack-Surface Management) module • Discover sub-domains and other Internet-facing assets automatically • Scan and track open ports / running services, flagging changes over time • Store historical data so trends and newly exposed services are obvious • Expose clean REST endpoints for each function (FastAPI or similar in Python preferred) 2. Dark-Web monitoring module • Crawl and scrape TOR “.onion” sites for brand, email or credential mentions • Correlate findings with the asset list from the ASM mod...

This is a college-level project: an end-to-end encrypted chat application built in Android Studio with a MongoDB back-end. All user accounts should authenticate strictly through email-and-password flow; no phone or social logins are needed. Core experience • One-to-one and group chats must be fully encrypted on the client before any data leaves the device, then stored in MongoDB in ciphertext. • Group chat creation, member invites, and message history sync are required. • Chats should support file sharing (images, documents, etc.), voice messages, and simple user-profile customisation such as avatar and status text. UI/UX Keep the interface clean and fast: a sign-in/sign-up screen, chat list, message view with attachments, and a lightweight profile edit screen. Mat...
I already have a complete React-based portfolio site that connects to a MongoDB back end, and the design is fully finalized. What I now need is a smooth deployment to my Hostinger hosting account. Please handle: • Full deployment of the codebase to Hostinger • MongoDB database setup and connection testing • Final checks to ensure the site is live and publicly accessible Feel free to work with any standard deployment tools or CI scripts you prefer, as long as everything runs reliably on Hostinger’s environment. Once it is live, I’ll verify that every portfolio page renders correctly, all API routes return expected data, and the SSL certificate issued by Hostinger shows the padlock icon. If you have recent experience pushing React/MongoDB projects to Hos...
I’m ready to roll out Anthropic’s Claude across the company so it can shoulder two core responsibilities—data analysis and project management. To do that, the agent must read (and potentially write) directly against our in-house NoSQL database. Think Mongo-style collections rather than traditional SQL tables; all the information that drives our operations lives there, so smooth, secure connectivity is non-negotiable. Here’s what success looks like to me: • Claude can accept natural-language questions, translate them into NoSQL queries, and return clean, easy-to-read insights or visual summaries. • The same agent can create, modify, and track tasks in our existing project-tracking tool through an API/webhook, keeping teams updated automatically. •...

This project, Navigator360, is designed as an "AI-Powered Strategic Growth Platform." It functions as a comprehensive tool to help businesses generate strategic analyses, market trends, and growth plans. The project is structured into two main parts: a Frontend application and a Backend API server. 1. Frontend (Navigator360) The frontend is a modern, single-page web application built to offer users an interactive dashboard and platform experience. Tech Stack: Built using React and bundled with Vite. Styling & UI: It uses Tailwind CSS for responsive design and lucide-react for iconography.

My FastAPI + MongoDB project already runs smoothly on the back-end, but the User profile page on the React 19 front-end is misbehaving. I built the interface with React Router and shadcn/ui components; somewhere in that stack the page is rendering inconsistently and occasionally throws console errors that break navigation back to the dashboard. Here’s what I need from you: • Pinpoint the root cause of the User profile page issues (layout glitches, state not persisting, any runtime errors). • Deliver clean, well-commented fixes in a pull request or patch, keeping to the existing code style. • Verify the solution across modern browsers and confirm the route still works seamlessly with React Router. You’ll have access to the Git repo, a brief tour of the com...
I’m putting together a public showcase of my full-stack React + Node.js + MongoDB work and need each project running online so visitors can play with it in real time. The emphasis is on data-visualisation: every demo should open to an interactive dashboard that lets users explore charts and drill down into the data. Here’s what I expect from you: • Spin up (or migrate) each project so the React front-end, Node/Express API, and MongoDB Atlas cluster are all deployed and talking to one another. • Host the front-end on a service such as Netlify or Vercel and the API on Render, Railway, or similar—whatever gives a fast, no-sleep free tier is fine. • Surface the dashboard immediately after loading; no authentication flow is required for these demos. &bul...
The goal is to build a modern, fully responsive web application with React on the front-end and a Node.js back-end. Every screen should adapt smoothly from desktop to mobile while maintaining a clean, intuitive UI. All code must be modular, clearly commented, and organised into logical folders so future contributors can jump in without a learning curve. Authentication Users need to sign up and sign in with both traditional email/password credentials and social media providers such as Google and Facebook. If we can architect it so two-factor authentication could be layered on later, even better. Dashboard scope After login, each user lands on a personalised dashboard that includes: • User profile management (edit avatar, bio, contact info, change password) • Analytics an...

I’m working on a full-scale college web application and need someone who can take ownership of the entire MERN stack from start to finish. That means shaping a responsive React.js front-end, wiring it to a robust Node.js + back-end, and modelling the data layer in MongoDB so everything talks to each other seamlessly. The core of the work sits in Node and Express. Because this is a college-level build, the APIs, server-side logic, and database hooks all have to be clean, well-documented, and easy for reviewers to follow. If you’re used to designing RESTful endpoints, handling authentication, and tightening security middleware, you’ll feel right at home here. On the front end I’ll count on you for component structure, state management, and smooth routing. Think Rea...
