    Our occupational-health booking system is already live and about 99 % feature-complete, yet every time code is touched new problems appear.

    I need a complete Matka gaming solution built from scratch—a responsive web site plus a dedicated Android app. The core of both platforms is a smooth betting interface where players can pick numbers, place bids, and instantly see odds.

    I need a small, browser-based application that lets me open the device camera, snap a customer photo, and instantly save the image with an automatically generated sequential number (001, 002, 003 …). As soon as the picture is stored, a form should appear so I can record the customer’s full, detailed profile—name, address, contact numbers, email, and any extra fields specific to my business. Because the database will grow quickly, I also want to reach information fast and move it elsewhere when needed. To make that possible, the build must include: • Search functionality, including a multi-criteria search that can filter by any field or the photo number • Customer data export in a common format (CSV or Excel) • User authentication and login so only au...

    I’m building a clean, modern, and minimalist informational site and need a UI/UX partner who can take the whole front-end from concept to functional pages. The single most important factor is effortless, user-friendly navigation; every section should feel obvious and intuitive on desktop, tablet, and mobile alike. Here’s how I picture the flow: • Start with low-fidelity wireframes that map out a simple, well-labeled structure. • Progress to high-fidelity mock-ups that capture a minimalist aesthetic—ample whitespace, restrained color palette, crisp typography. • Hand off fully responsive HTML, CSS, and vanilla JavaScript files ready to drop into my hosting environment, along with brief implementation notes. I’ll supply the core content and brand...

    I run a growing interior design studio and need a fast, modern-looking website built with Next.js. The look and feel should be clean, modern and minimalist, mirroring my aesthetic and letting photographs of past projects take centre stage. Scope I want a full website, meaning at minimum a polished Home page, a visually driven Portfolio/Gallery, and an easy-to-find Contact page. Feel free to suggest an About or Services section if it improves the flow. All pages must load instantly, so please lean on features such as image optimisation, static generation, and smart code-splitting. Visual direction Think white space, restrained colour palettes, balanced typography, and generous hero imagery. Subtle micro-interactions are welcome as long as they do not compromise performance. Core req...

    I need a lightweight chat application where students can simply talk to one another while they study.

    I need a web developer who can create a modern, minimalist site that becomes the central hub for our college program’s upcoming events. The key objective is to showcase event details clearly and allow visitors to register through an intuitive online form that feeds directly into our internal spreadsheet or database. The site must look and behave flawlessly on phones, tablets, and desktops, so solid experience with responsive design principles (CSS Grid/Flexbox, media queries, or a proven framework such as Bootstrap or Tailwind) is important. I want clean, lightweight code, fast load times, and accessibility best practices baked in from the start. Design-wise, think plenty of white space, balanced typography, and a restrained color palette that aligns with our program’s brandi...

    Please read carefully before bidding. Project Goal: I need a custom Tampermonkey userscript built specifically for the sign-in page of the IVAC portal (). The goal of the script is to capture the client-side encrypted payload token (the "c" parameter) and output it cleanly to the browser console on demand, WITHOUT actually submitting or reloading the form. The Technical Challenge: - The target login page utilizes Cloudflare Turnstile. - However, generating a standard Turnstile token is not enough. The frontend JavaScript on this portal intercepts the form data and applies custom client-side encryption/signing, outputting it as a parameter named "c" inside the final payload. - You will need to reverse-engineer the minified/obfuscated JavaScript files of the website to ...

    I’m a full-stack developer trainee who learns best by rolling up my sleeves and coding, so I’m looking for a tutor who can guide me through the complete web stack and accelerate my progress. The sessions must cover all three pillars—front-end, back-end, and database management—because I want to understand how every layer connects when building a real-world application. Front-end work will revolve around modern JavaScript/TypeScript frameworks (React, Vue, or Angular are all fine), component architecture, state management, testing, and performance tuning. For the back-end, I’d like to get comfortable with Node/Express or comparable frameworks, dive into RESTful API design, authentication, deployment, and containerisation basics. On the data side, we’ll ...
