I have a live mobile app that needs several quick fixes and small feature tweaks: • User notifications already appear correctly, but inside the notification settings screen I need an Add / Delete option so users can manage their own notices. • The Info button is presently inert. It must finally “Do” what it was meant to—react when tapped and complete its intended action rather than sitting idle. • In the admin area an unused “Donut” button slipped in during a previous update. Please remove it cleanly from both UI and code. • I want you to confirm whether a developer-level back door still exists. If any direct access remains, close it and leave only the standard, authorised paths. • Google sign-in is integrated but currently fails....

Only candidates with a Computer Science degree from a UK institution will be considered.

I’m rebuilding a web application whose backend currently mixes legacy PHP with newer modules. The stack centres on PHP (latest stable) and a MySQL database, and I need an experienced backend developer who can confidently step into an evolving codebase while also creating fresh, well-architected components. Here’s what I need tackled: • API development – design and implement RESTful endpoints that plug seamlessly into the existing logic and any new features we add. • Database optimisation – review schema, refactor queries, add indexes, and benchmark improvements so we can see tangible speed gains. • User authentication system – build a secure, token-based solution that fits the current login flow and is flexible enough for future SSO or OAu...

I need every part of my existing React-based CMS rewritten in Laravel so it can live inside – and ultimately be merged with – another application we already run on Laravel. All current CMS features move over, nothing left behind and the CMS project can be viewed at FitByShot.com. Once rebuilt, merge as one single project with the Laravel user-management and e-commerce modules that already exist in the other codebase. All the merged existing project will live behind a Login which is for Administration onlly. Treat those modules as black boxes: minor alteration with their internal logic, just make sure the new CMS calls their Login services cleanly and respects their models and migrations. After the migration, add two essentials: • Two-Factor Authentication for log-in (Lar...

I need a lean, working web application that lets teachers publish courses and students immediately start learning. The priority is speed to a usable MVP rather than polish, so clean, well-structured code and a straightforward interface matter more than pixel-perfect design. Scope of the first release • Authentication: only email + password, securely hashed, with clear separation between teacher and student privileges. • Course workflow: – Teachers create, edit and delete courses, then add lessons that can contain plain text or embedded video. – Students browse the catalogue, enroll, and view each lesson. • Homework loop: teachers post an assignment; enrolled students submit their work; the teacher can review it inside the platform. • Notifi...

I’m building an inquiry-led marketplace where the usual catalogue is flipped around: buyers post what they want to purchase, state their budget, and wait for sellers to pitch offers. The platform has to feel as familiar as any classifieds site yet be protected by a seamless escrow flow that only releases funds once the buyer confirms receipt. Core buyer-side flow • A “New Inquiry” form that captures the request, the buyer’s budget, and supports Image uploads, Category selection, and a Detailed description field. • After publishing, buyers can Edit advertisement, Cancel advertisement, or Share with social media at any time. • When a seller submits an offer the buyer can Confirm accepting offer, and once the good or service is delivered, Confirm re...

I’m launching a full-scale online arcade inspired by the polish and speed of CrazyGames, and I need the entire web platform engineered from the ground up. The focus is on high-quality HTML5 and WebGL titles that load instantly in the browser across desktop and mobile, so every technical choice has to revolve around performance, asset compression, and responsive design. Core experience • Games: Primarily HTML5, with WebGL support for more demanding titles. • Feel: Clean, lightweight interface that still looks like a major gaming brand. Page transitions should be fluid and the site must pass Core Web Vitals on mobile. • Hosting & publishing: I want a workflow where I can drop in new game builds, set metadata, and have the title live—think a small CMS or ...

I'm looking to develop a mobile application that will allow users to rent cars, bicycles, and motorcycles from nearby owners. Mobile application that enables users to rent different types of vehiclesfrom nearby owners.

Key Features: - User reviews and ratings - Real-time vehicle availability - Booking system with calendar view - In-app notifications for booking updates and reminders - Dashboard for hosts showcasing their vehicles, earnings, and ratings - In-app chat functionality Vehicle Discovery:...

I need a clean, well-documented Node.js solution that fetches JSON data from a specified API endpoint and turns it into a professionally formatted PDF made up exclusively of tables. The flow is straightforward: call the API, parse the JSON payload, map the fields to table columns, then render each table so it paginates gracefully and, when necessary, repeats headers across pages. Key points • Source data arrives solely from an API in JSON format—no manual entry or secondary feeds. • The PDF contains tables only; no images or free-form text blocks beyond table headers or footers you may add for clarity. • Any solid, maintained library is fine—pdfkit, Puppeteer, jsPDF, or a comparable Node.js toolset—as long as it supports custom styling (borders, alte...

I would like a clean, corporate-looking website built with a modern, mobile-first layout and a solid MySQL back end. The core structure must include Home, About, Services, Contact (with working form), Login & Register, and—if you can fit it in smoothly—an Admin Panel for easy content management. Design style The whole site should feel professional and trustworthy rather than playful; think orderly grids, plenty of white space, and a restrained colour palette. Key page notes • Services page: please weave in an area for client testimonials so prospects can see social proof at a glance. • Contact page: the form should trigger email notifications in both plain-text and HTML versions so I can route them through different inbox rules if needed. • Extra va...

Quero lançar um portal imobiliário focado na minha região, inspirado no modelo do ZapImóveis, onde proprietários possam anunciar imóveis para venda ou locação e interessados encontrem oportunidades rapidamente. O site precisará: • Duas áreas de usuários bem definidas. Vendedores / locatários poderão publicar imóveis e visualizar os planos disponíveis; compradores / inquilinos terão acesso aos anúncios e filtros de busca. • Modelos de cobrança por assinatura mensal e também pacotes avulsos de anúncios. Todo o fluxo de contratação deve ocorrer dentro da plataforma, com renovação automática e controle de val...

I’m putting together a modern web application and I want it engineered end-to-end with React on the front and Node.js on the back. Real-time updates are central to the experience, so you should be comfortable wiring WebSockets or a layer that keeps every client instantly in sync without page refreshes. Here’s the flow I have in mind: • Design a clean, reusable component architecture in React (hooks, context, or Redux—whichever you know will scale). • Stand up a lightweight Node.js/Express API that pushes and receives real-time events efficiently. • Connect the two, secure the traffic, and deploy to a cloud host so I can test live. I’ll supply wireframes and the basic data model; you translate that into working code, commit to Git regularly, a...

We are building an ad monetization platform similar to Freestar and AdPushup. The platform helps website and app publishers maximize their ad revenue. We are a Google Partner with access to Google Ad Exchange (AdX) demand and have accounts with multiple SSP/Prebid partners. Note: We are not currently an MCM (Multiple Customer Management) partner, so AdX demand is served through our own GAM account. The platform consists of three main parts: • A JavaScript tag that publishers place on their website which handles everything: running Prebid auctions, calling GAM, rendering ads, and reporting data back to us • A backend / admin dashboard where we configure everything per publisher: ad units, bidders, floors, formats, and settings • A publisher-facing dashboard ...

What We Are Building A centralized system where we can: onboard publisher websites and apps deploy monetization automati...

My WordPress site feels snappy on the front-end, yet the server is taking too long to assemble each page. The priority is clear: cut backend processing time so visitors receive content far faster. The work centers on three intertwined areas: • Plugin performance – audit active plugins, remove or replace heavy ones, and refactor any custom code that slows execution. • Database queries – profile slow queries, add or adjust indexes, and fine-tune wp_options or autoloaded data to reduce query count and execution time. • Theme code – streamline template files, eliminate redundant functions, and ensure hooks run only when required. I already handle basic caching and asset minification; the bottleneck lies deeper. Please benchmark before and after (...

I want visitors to enter their date, exact time, and place of birth on my WordPress site and instantly receive a full suite of Vedic astrology results. The module needs to compute and display every divisional chart from D1, D9, D10 through D60, show lucky numbers and lucky colours, and lay out key insights such as planetary positions, house (Bhava) placements, and Nakshatra positions. I do not yet have production-ready code, so please bring or build the complete calculation engine. Whether you adapt an open-source ephemeris (e.g., Swiss Ephemeris) or write fresh PHP/JavaScript routines is up to you, as long as the output is accurate and the front-end embeds cleanly through a shortcode or block. Acceptance will be based on: • Correct rendering of all D1–D60 charts with proper...

I’m ready to launch a dedicated chiptuning site where visitors can see what I offer and reserve a slot right away. The core of the project is a clean service-based booking flow: clients choose their vehicle, pick from my predefined tuning packages, then lock in a date and time. Here is exactly what I need built: • Responsive website with a modern automotive look and clear service pages. • Booking module that supports appointment scheduling and lets users select specific service options before checkout. • User accounts should be available but not forced; guests can book, while registered users gain the benefit of tracking past appointments and faster re-booking. • Admin area where I can add or edit tuning packages, adjust time slots, and receive email not...

I have roughly 25 Microsoft Word templates with fixed wording and clearly marked placeholders. In seven days or less I need a working web application that lets a registered user fill a form, upload any required pictures, pay through Stripe, and instantly receive a freshly generated .docx where both the text and the images have been merged into the correct spots. Here is what must be in the finished product: • Secure authentication with two roles only—admin and user. • Stripe integrated so a payment successfully unlocks the generate-document action. • A backend service that stores the templates, injects the incoming text and images, and streams the completed Word file without errors or broken formatting. • An admin screen where I can upload, remove, or edit...

I’ve put together the entire front-end of my React Native app and now I’m ready to connect it to a real backend. During a live Zoom or Microsoft Teams session I want to screen-share and work side-by-side while you guide me through each step. Supabase is the database service I’d like to use (or firebase), though I’m open to brief comparisons with Firebase if a decision point comes up. I have no prior backend experience, so you’ll need to walk me through project structure, environment variables, and deployment best practices. Whether the supporting server logic ends up in Node.js or another lightweight option, keep everything clear and beginner-friendly so I can maintain it afterward. We must cover: • Authentication setup – phone OTP authentication....

I need a developer who knows BigCommerce inside-out to extend the store’s core functionality. The immediate focus is shipping logic: I want new shipping methods added, existing rates adjusted, and clear zone-based rules so customers see the right options every time they check out. Changes must be configured in the control panel rather than hard-coded, so I can edit them later without touching code. Alongside shipping, product pages require more flexible variations. Think custom option sets that handle complex combinations cleanly, keep inventory in sync, and present a smooth selector on Stencil templates. Deliverables • New shipping methods visible at checkout and in the admin panel • Rate tables updated and verified for accuracy across all defined zones • Zone...

I want to create a mobile application inspired by Rapido that lets users book taxis instantly. The flow should feel like a friction-free service-booking platform: pick-up and drop-off locations, see nearby drivers, confirm the ride, then track the car live until arrival. To keep things clear, here is what I expect to be included: • Real-time tracking so riders can follow the driver’s route from acceptance to drop-off. • A driver ratings & reviews system that lets passengers leave feedback and see an average score before they confirm. • Multiple payment options—card, wallet, and cash on arrival at minimum—handled through a secure gateway. iOS and Android releases are both in scope. I will supply brand assets; you will handle UI/UX, backend, driv...

I run a product stack built entirely on Cosmol 5.5 and need an experienced hand to stay on board for the long haul. Day-to-day work ranges from squeezing every bit of performance out of the current setup, through rolling out brand-new modules, to jumping on unexpected bugs before they disrupt users. Because the platform touches both front-end and back-end layers, a solid grasp of user-facing polish, data-processing logic, and third-party system hooks will serve you well. The codebase lives in Git; regular commits, concise pull-request notes, and clear change logs are non-negotiable. Whenever a feature ships, I’ll expect matching inline comments and a quick markdown brief that explains configuration steps or edge-case behaviour so future maintenance stays painless. Communication happ...

I’m forking and need a seasoned TypeScript engineer who is totally at ease working Git-first and can dive straight into a Nostr codebase. The immediate goal is to introduce a suite of non-public features around improved listings and, above all, a powerful personalised content-suggestion layer. Scope • Extend the existing front-end and back-end (TypeScript, React, Node) with the new private listing modules I will outline in Figma and Notion. • Build a recommendation engine grounded in socio-psychology principles rather than the usual collaborative or content-based filters. I will supply the research notes and sample scoring model; you will translate them into production code, unit tests, and API endpoints. • Keep everything behind a feature flag so the public fo...
