    I need a seasoned PHP developer to design and build a clean, well-documented API from the ground up. The project centres entirely on backend logic—there is no front-end work—so your focus will be creating efficient endpoints, solid authentication, and clear JSON output. Here’s what I have in mind: • Code in modern PHP (8.x preferred) and follow PSR standards. • Use a framework or micro-framework you’re comfortable with—Laravel, Lumen, Slim, or even plain Composer packages are fine—as long as it stays lean and easy to maintain. • Include token-based authentication, structured error handling, and basic rate limiting. • Provide concise documentation (endpoints, parameters, responses) plus a Postman or Insomnia collection so I can...

    I need a small application that lets me push short project-status messages to three specific business owners on WhatsApp without any fuss. The core idea is speed and reliability: write the update once, hit send, and know it reached the right people. Here is what matters most to me: • A friction-free interface—web, desktop, or mobile, I am open to what you feel will be the most dependable path. • Straightforward contact management for just three recipients, yet flexible enough that I could add or edit contacts later. • A smooth workflow for composing, reviewing, and sending updates; if message templates or scheduling make that smoother, feel free to incorporate them. • Solid delivery—whether you leverage the official WhatsApp Business API, an approve...

    My Node.js-based MLM platform has already gone live, but the July payout module is mis-calculating commissions. The problem sits squarely in the commission calculations: multiple plans feed into fixed-percentage rewards that must respect individual ranks, downlines, legs, and various payout caps. Because one wrong figure ripples through every leg, accuracy is critical. You will receive full access to the existing codebase, database schema, and a sample data dump from July. I need you to: • Trace the current commission logic for all plans and identify where it diverges from the expected fixed-percentage model. • Refactor or rewrite those sections so every user’s rank, leg balance, and cap is honoured. • Add clear unit tests (Jest preferred) that replicate July sce...

    This project involves end-to-end programming work—from pinning down the exact requirements with me, through architecture and coding, all the way to testing, documentation, and deployment. The scope is still flexible: it might turn into a brand-new build, an upgrade of an existing system, or an integration piece that pulls several services together. I’m open on the tech stack; proficiency in Python, JavaScript, or Java would be ideal, but feel free to suggest alternatives if they serve the goal better. Expect to handle version control (Git), write clean, well-commented code, and provide clear hand-off material so future maintenance is straightforward. When you respond, outline: • A brief overview of how you’d approach discovering and refining the requirements ...

    I’m putting together a full-featured Student Management System written in Java and I’d like a developer who can take it from design to a runnable application. At its core the program must handle student enrollment, grade management and attendance tracking, all persisted in an SQLite database. Interface requirements The system should work in two modes: a straightforward CLI for quick admin tasks and a clean, intuitive GUI (Swing or JavaFX—whichever you’re most comfortable with) for everyday use. Switching between the two should not duplicate business logic; the UI layers need to call the same underlying service classes. Key expectations • Robust object-oriented code, well documented • CRUD operations for students, courses, grades and attendance reco...

    I’ve just upgraded the site to WooCommerce 10.4.3 and the new strict session nonce checks broke the cart page in my Imarket theme. The first click on the “Remove” icon still works, but because the theme’s custom AJAX call only refreshes the header fragments and not the cart table itself, a second deletion throws a nonce error until the customer refreshes the page. All I need is a minimal, surgical fix that restores normal, consecutive item deletion on /cart/: • Investigate the current JavaScript / PHP handling the wc_cart_remove_item request inside the Imarket theme. • Bring the process back in line with WooCommerce 10.4.3 nonce requirements or hook into Woo’s native fragment-refresh so the cart table, totals and header fragments all stay in sync...
