    I’m running a self-hosted MeshCentral server on Ubuntu 24 Linux and I need two equally important improvements added to its web interface. 1) Per-user concurrent-session cap From the UI I want to be able to enter a number that represents the maximum simultaneous device connections or remote sessions a given user can open. Once that threshold is reached, additional connection attempts must be blocked until an existing session ends. The setting must work on a per-user basis without impacting other users or global server limits. 2) Account expiry date control I also need a date picker in the user–edit screen that lets me set an explicit expiry date for an account. When that day arrives the account should become disabled automatically, with no manual cleanup required. An a...

    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...

    My site stores user records in MySQL and already has a username-and-password form, yet anyone who bookmarks the internal page can still open it directly. I need that loophole closed. Your job is to wire the authentication checks correctly so every visit to the protected page is first validated against the existing MySQL session. If the visitor is not signed in, they must be redirected to the login form—no exceptions, no back doors. While doing this, make sure the credentials stay encrypted in transit and the passwords remain securely hashed inside the database. Please refactor or add the minimum necessary code (PHP, Node, or another language is fine as long as you note which one), comment it clearly, and include a short read-me so I can plug it straight into production and test.

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.

    I’m building a new white-label iGaming suite that bundles an online casino and a full-featured sportsbook into a single, scalable platform. The project covers everything from the real-time odds engine to the front-end lobby, and I need a senior full-stack developer who can own the build end-to-end. The back end must be modular—micro-service friendly, containerised, and ready to plug in third-party game providers, odds feeds, KYC tools, and multiple payment gateways. A modern stack such as Node.js or Go for the services, TypeScript/React (or similar) for the client, and a cloud environment like AWS or GCP with Docker/Kubernetes for orchestration is preferred, but I’m open to your proven alternatives if they shorten time-to-market without sacrificing reliability.

    I have already trained and deployed a Logistic Regression model in Streamlit that classifies breast-tumour samples as malignant or benign. What I need now is a polished data-visualization layer so users can quickly grasp how each feature influences the prediction. My immediate focus is on bar-chart visualisations. I want clear, well-labelled bars that compare malignant vs. benign distributions, show feature importances, and surface any other insight you think adds value. The work should plug straight into my current Streamlit app and read from the same Pandas DataFrame I am already passing to the model. Although the main task is visualisation, I am also experimenting with feature selection, so if your code can be structured in a way that makes it easy to toggle feature subsets, that wi...

    I’m building a small web-based tool, code-named “Socmed Evakuator”, that zeroes in on Twitter data and shows how an account’s follower count changes day by day. The goal is clear: connect to the Twitter API, collect the right numbers automatically, and present them in an easy-to-read dashboard so I can spot trends without digging through spreadsheets. Here’s how I picture the workflow: after authenticating through Twitter’s latest OAuth flow, the app should fetch follower totals on a schedule I can tweak (hourly, daily, etc.), store each snapshot in a lightweight database, then visualise the growth curve with a clean chart. I’m flexible on the stack—Python with FastAPI, Node.js with Express, or another modern framework is fine as long as the...

    I’ve built a dynamic web app on Replit that relies on a PostgreSQL database and uses Clerk for user sign-up and login. I now need the whole project running smoothly on Railway. Here’s what I’m looking for: • Move the existing codebase from Replit to a new Railway project • Provision or connect the PostgreSQL instance on Railway and migrate the current data • Update all environment variables (including Clerk keys) so authentication continues to work without any interruption • Adjust build or start scripts if needed so Railway’s deploy pipeline runs cleanly • Verify that sign-up, login, and every database-backed route behave exactly the same in production If you’ve already deployed apps with Clerk and PostgreSQL on Railway, th...

    I want to keep my order tracking lightweight, so I’d like the entire solution built in a spreadsheet environment (Google Sheets or Excel—whichever you’re fastest with). Users will open a clean form-style interface, fill in customer details, product, quantity, price, and hit “Submit.” Those entries should drop into a master table behind the scenes without exposing formulas or letting anyone accidentally overwrite data. From that same file I also need a concise dashboard or pivot-style report that totals sales by day, week, and product so I can spot trends at a glance. Because all data will be typed in manually, the form must include basic validation (no blank mandatory fields, numeric checks on quantity/price, date picker, etc.) to keep everything consistent. ...

    I need a web experience that mirrors the interactive sitemap on The same fluid SVG zooms, building highlights, unit pop-ups, and motion effects must be recreated, but the site must also let me keep everything current without touching code. Technology & stack • The core of the map must be built in HTML5 with SVG so it scales sharply and loads quickly on all devices. • Behind it, I want a lightweight custom CMS—something purpose-built rather than WordPress or Drupal—so I can sign in, search for a unit, and update pricing, status, tool-tip text, or imagery in seconds. User interactions • Click to view full unit details in a slide-in or modal. • Hover (or tap-and-hold on mobile) for an at-a-glance summary. What I need from you 1. A fully func...

    I need a WooCommerce-savvy developer to sort out one very specific issue: the checkout link that Facebook and Instagram generate for my Meta Shop must point to instead of the default WooCommerce endpoint. In practice, when a customer taps the “Checkout” button inside Facebook or Instagram, they should land on that custom page with the exact product they selected already in place, ready for payment. Here is what is already clear on my side: • WordPress and WooCommerce are fully installed and live. • The shop is connected to Meta Commerce Manager and products are feeding correctly. • I simply need the URL redirection logic handled—no changes to payment gateways for now. Your job is to: 1. Configure the correct checkout URL within Facebook/Instagram...
