The business model is straightforward: DLD provides a complete online booking system to Schools of Motoring for a recurring monthly fee.

The system needs to support Schools of Motoring with: One or multiple instructors Instructors qualifie...

I need a complete social media application built for both iOS and Android that lets users create standalone accounts, share photos or short videos every day, and chat instantly with one another. Core scope Users sign up with email or phone, set up a profile, and immediately start posting to a scrolling feed. Each post can contain an image or video, a caption, and basic engagement options (like, comment, delete / report). Real-time one-to-one and group messaging must be available inside the same app with push notifications. No external log-ins are required; accounts stay completely independent of Facebook, Instagram, or Twitter. Live streaming is not part of this phase, but the architecture should leave room to bolt it on later. Technical notes A shared codebase—React Native, ...

I need a single software tool built for Windows that brings together modules written in C#, Java, JavaScript (with Node.js), and Python. Each language already plays a specific role in my current workflow, but everything now lives in separate scripts. The goal of this project is to consolidate that functionality under one cohesive interface so the user experience feels like a unified application, even though different runtimes sit behind the scenes. Here is what I have in mind: • C# and Java components handle performance-critical routines and existing libraries I can’t easily replace. • Node.js and browser-side JavaScript power a lightweight GUI/dashboard. • Python remains in charge of data preparation and quick scripting tasks. Your job is to architect the g...

I need an online registration form that visitors can fill out on my existing site. It has to look clean, match my current branding, and work smoothly on mobile as well as desktop. When someone submits the form, the data should be stored in a downloadable file (CSV is fine) and an email confirmation should go both to the registrant and to me. Basic anti-spam protection such as Google reCAPTCHA is important so we keep bots away. I’m open to the underlying tech—plain HTML/PHP, a lightweight JavaScript solution, or a WordPress plugin—whatever you’re most comfortable with, as long as you can hand it over ready to embed and easy for me to tweak later. Deliverables: • Fully tested, responsive form page with back-end processing • Automatic email confirmation pl...

I already have a single-page site online and need two additional, fully-styled pages added to it. 1. Contact Us • Form fields: Name, Email, Message • On submission the data simply needs to reach me (email handling or a lightweight back-end script—whichever you are most comfortable with). • Keep the look and feel consistent with the existing one-pager. 2. Join the Waitlist • Form fields: Name, Email, Phone • Same handling requirements as above; no verification or CAPTCHA is necessary. Both pages must be responsive and slot neatly into the current codebase without breaking anything already live. Once they are in place and the submissions arrive successfully, the job is complete.

I’m creating a platform where users can browse, book, and safely interact with “rental boyfriends” for virtual companionship. The core flow is straightforward: discover profiles, check availability, reserve time slots, and chat before and during the booking. Here’s what I need built from scratch: • A clean front end—responsive enough to run smoothly in any browser today and easy to port into a mobile app later. • A secure back end that stores profile data, reviews, schedules, and completed sessions while keeping personal details private. • Real-time chat and video hooks so clients can connect instantly once a booking is confirmed. • A simple, scalable authentication layer; I’m open to email/password, phone verification, so...

I have an existing site that was originally assembled with the help of Claude, and while it functions, it no longer meets my standards for reliability, security, or professional appearance. I’d like an experienced web developer / designer to take the current build, tighten up its back-end, and present a polished front-end that instills confidence in visitors. Scope of work • Reliability: Analyse the current codebase and hosting setup, then resolve anything that could slow pages down, cause intermittent downtime, or throw avoidable errors. • Security: I need best-practice hardening throughout—think SSL/TLS implementation, firewall configuration, and any additional measures you feel are necessary after a quick audit. • Design refresh: Update the layout, na...

I’m building a commercial SaaS platform whose primary mission is to guide field technicians through every stage of an industrial Wi-Fi deployment. The solution must ship as three tightly-integrated components: • A cross-platform mobile app (iOS and Android) that walks technicians step-by-step through installation, records signal-strength, interference and latency measurements, captures photo evidence, and drives the full project-acceptance workflow. • A cloud-hosted, scalable backend with secure data storage, role-based access control and an API powering both the app and the web. • A browser-based administration panel for project setup, live progress monitoring, workflow updates and automatic PDF acceptance-report generation. My top priority is an MVP that pr...

A web-based application designed for online meetings and collaboration was developed over a few years, but due to a restructure of the current developer company, they cannot continue to develop. The technology used includes node.js, javascript, html, css, and fabric. I was told that the new developer needs to have skills and experience in node.js, javascript, html, css & fabric. The task involves fixing specific issues that I will provide in a detailed list. Developers must: 1. Fix the identified issues without altering the existing format. 2. Confirm with me after each fix for testing before proceeding further. Further development beyond these fixes will be discussed separately and paid for accordingly.

I’m ready to move my existing mobile app to the next stage by introducing two key capabilities: secure email-and-password sign-up/login and a fully functioning in-app purchase flow. The current build is stable but still lacks these revenue-driving and user-management features, so I’d like to fold them in without disrupting what already works. Scope • Implement robust user authentication based strictly on email and password, complete with validation, forgotten-password flow, and token-based session handling. • Integrate in-app purchases (consumables and/or subscriptions, depending on what the store guidelines permit) so that purchases are processed, verified, and recorded on the backend. • Refactor or patch any surrounding code that these features touch to ...

I need a web-based dashboard, powered by the DhanHQ API, that continuously scans NSE and BSE option chains and fires in-app alerts whenever unusual activity appears. All the core metrics—RVOL, GEX, VEX, Gamma-Regime, Vex-Regime, Charm, CE & PE walls, Gamma-flip level, Dealer-Flow Score, and IV Rank/Percentile—must be user-configurable from the interface so I can tweak thresholds on the fly without touching code. The workflow I have in mind is simple: the backend fetches live data, applies my chosen parameter settings, calculates the signals, and streams results to a responsive web UI. When any metric crosses the threshold, the system should display a notification inside the application immediately and log the event for later review. Real-time charts, heat-maps, and summary...

I run a typing center and I want visitors to fill out a small set of application forms directly on my site instead of handing me paper copies. The forms include both Government and Educational applications, and each one must stay fully editable so I can update fields or wording whenever regulations change. What I need you to build is a lightweight software layer—whether it ends up as a WordPress plugin, an embeddable HTML widget, or another clean solution—that drops into my existing site and keeps everything in the same look-and-feel. The must-have feature is Auto-save so customers never lose their progress if they pause or lose connection.

This project entails building a clean, well-structured portfolio website from scratch with Flask and Python as the core stack. The finished site should showcase a handful of project pages, an about section, and a contact form that sends email via a simple backend route. Beyond the visible pages, I place strong emphasis on organised, readable code: follow PEP 8, group related logic in blueprints, and include docstrings and a concise README so that I (or any future maintainer) can extend the site easily.

I already have an unfinished application that needs attention in four intertwined areas: Frontend UI/UX, Backend server logic, AI model enhancement, and the overall move toward a reliable SaaS offering. The existing code base is functional but fragmented; the original developer left limited documentation and I’m not completely sure which tech stack was finally chosen. You’ll start with a brief audit of the repository to identify the frameworks and libraries in place, then recommend whether we keep, refactor, or replace any layer. Frontend • Polish the current interface, improve component structure, and ensure responsive behaviour across desktop and mobile. • I’m aiming for a friendly, modern look—feel free to leverage React, Angular or Vue once you co...

I’m building a web platform where clients can reserve a “rental boyfriend” through a dedicated request-based booking flow. The core of the project is the booking engine itself—no instant confirmations, chats, or public profiles for now—just a clean, secure way for someone to submit a booking request and wait for approval. Here’s what I need developed: • Request Booking Workflow – Calendar to pick a date and time – Form field for “Preferred activities” so the client can outline how they’d like to spend the session – Automatic email/SMS notifications to both sides when a request is placed, accepted, or declined • Admin Dashboard – Simple queue showing all incoming requests with accept /...

I already have an IoT mobile app with its backend up and running; however, the user experience suffers from noticeable latency. My goal is to polish the codebase, trim anything that consumes resources unnecessarily, and move the entire stack from Google Firebase to a VPS that uses MQTT for real-time messaging. What I need you to tackle • Profile both the mobile client and the existing Node/JavaScript backend, pinpointing functions, background tasks, or logging that slow the app down, then refactor or remove them without breaking current functionality. • Reduce round-trip time for screen loads, device data sync, and control commands to well under a second on a normal 2G connection. • Stand up a secure VPS (Ubuntu preferred), install and configure an MQTT broker such as...

I’m developing a professional-networking platform exclusively for Android and need the full application coded and ready for launch on Google Play. The core experience centres on meaningful professional connections, so fluid in-app messaging is essential. Users must be able to start one-to-one or group chats instantly and exchange photos or short videos without noticeable delay or quality loss. All accounts will be created and secured through phone-number verification; no email or third-party social logins are planned, so the onboarding flow has to handle SMS code delivery, validation, and graceful error handling. Once inside, users can update a quick profile, search or receive suggestions, start a chat, and share media directly from the camera or gallery. Backend architecture, da...
