移动开发 Jobs

The job has two clear parts that connect directly to revenue: 1. Mobile-site refinement • Polish the current user interface so visitors can move effortlessly from landing page to checkout on any phone size. • Tighten on-page SEO (structure, meta tags, schema, internal links) so Google can surface the site more often on mobile searches. (Overall loading speed is already reasonable, but if you spot quick wins we can roll them in.) 2. Facebook / Instagram campaign build-out • Strategy, creative, audience setup, budget pacing and launch—all centred on one goal: generating leads and sales. • Audiences are already sketched by specific age brackets, geographic focus and interest / behaviour clusters; your task is to translate these parameters i...

I need a clean, corporate-level portfolio built with the latest version of Bootstrap. The overall mood should stay professional, yet I still want it to feel lively by leaning on a bright, vibrant colour palette instead of the usual muted neutrals. This site will host my web-development case studies, so code-friendly presentation matters. Scope The template must include an About Me, Projects, and Contact section, each laid out for clarity on desktop, tablet, and mobile. A fixed, mobile-friendly navigation bar should glide smoothly to each section. Project cards have to be visually striking, quick to scan, and coded for easy duplication as my portfolio grows. Subtle hover effects and light, tasteful animations are welcome so long as they do not compromise load time. Technical expectation...

My static HTML site looks great on desktop but stumbles on phones, and I need it polished for an upcoming user-testing round. The focus is threefold: • Mobile responsiveness – The navigation menu, all image / gallery components, and every form or input field must render and behave flawlessly on common mobile breakpoints. • Code & visual declutter – Strip out unused scripts and styles, remove any duplicate content, and trim excessive page elements so the pages load fast and remain easy to maintain. • Scalable content sections – Re-work the current markup so I can drop in new blog/news items and additional media-gallery entries via simple placeholders, without introducing a full CMS. Everything is plain HTML, CSS and a little vanilla JavaScript right ...

I need help fixing a specific issue in an existing Android app. The project is already built. It was originally created with Lovable AI, but it is now exported as a normal React + Vite project using Capacitor for Android. Backend/auth is Supabase. The app was rejected by Google Play because it still seems to redirect or reference Lovable. I need someone to review the exported source code and Android/Capacitor configuration, remove/fix any Lovable references or redirects, and make sure the app works correctly with Supabase and Google Play. This is not a full app development project. The app already exists. Required experience: - React + Vite - Capacitor Android - Supabase Auth - Android build process - Google Play Console / app rejection fixes What I need: 1. Review the project. 2. Id...

Necesito desarrollar una app de citas que funcione de forma nativa tanto en iOS como en Android. El único módulo imprescindible en esta primera fase es un sistema de emparejamiento que utilice un algoritmo personalizado; no busco incorporar mensajería interna ni perfiles de usuario por ahora, así que el enfoque estará 100 % en la lógica de match. Qué espero recibir • Código fuente limpio y documentado para ambas plataformas • Implementación del algoritmo de emparejamiento, incluyendo variables configurables y registro de métricas básicas (aciertos, rechazos, etc.) • Instrucciones claras para compilar y probar la app en Xcode y Android Studio • Una breve guía técnica don...

I am assembling a small, 14 members WhatsApp group to beta-test an Android application that forms part of a school project. To take part you must have an Android phone and an active Gmail account that can receive any permissions or review prompts Google may send during the test period. Once added to the WhatsApp workspace you will: • Keep a simple testing log, noting findings on user-interface usability, performance and speed, bug or error occurrences, and any additional items Google flags during review. • Respond promptly (within the same day) to questions or tasks I or the team lead post in the chat. • Stay available and engaged for 14 consecutive days max —the window in which Google typically issues feedback. The assignment ends only when Google confirms ...

My browser-based 3D maze () works smoothly on desktop, yet mobile browsers choke. I need an experienced web-game optimiser to: • Diagnose the bottlenecks in the current Web build (likely WebGL asset size, compression, streaming, or shader setup). • Apply best-practice fixes so the game opens quickly and runs fluidly on standard Android and iOS browsers without breaking the existing desktop experience. • Provide a reproducible build process and a brief change log so I can maintain it going forward. Acceptance criteria – Game loads in under 5 seconds on a typical 4G connection using Chrome’s network throttling. – Sustains ~30 fps on a mid-range Android (Pixel 4a class) and iPhone SE. – No new functional regressions on desktop. Deliverables...

I want to setup the mobile app

We have an Android app (TC58) that prints ShipStation shipping labels (4x6 PDF) to a Zebra mobile printer over Bluetooth. We need a definitive fix for unreliable PDF Direct printing and a robust default path that works across power cycles and app sessions. Current setup Device: Zebra TC58 (Android handheld) Printer: Zebra mobile thermal printer (Link‑OS 6.x) over BLE Labels: ShipStation 4" x 6" PDFs (~63 KB) SDK: Zebra Link‑OS Android SDK (Bluetooth + FileUtil/sendFileContents) What we’ve tried and observed We toggle (PDF Direct) per print: set to pdf before print, none after. This is wrong per Zebra docs; only applies after a printer restart. After the first successful label, subsequent prints often fail silently (no label) or “corrupt” printer state ...

I need a straightforward Android application that lets a user record daily expenses and keep an eye on their spending habits over time. Core workflow is simple: the user adds an expense, assigns one of five fixed categories (Food, Transport, Shopping, Bills, Other), and can later update or remove that record whenever needed. Every entry is stored locally with Room/SQLite so everything works offline. The interface can stick with the default Android UI components; polished visuals are welcome, but I do not require a full-blown Material makeover. What matters is a clean layout, dark-mode support, and snappy navigation between the main screens: • Dashboard – an overview that totals weekly and monthly spend, plus a running balance. • Detail list – searchable and filter...

I’m planning a new utility-style Android application and want to team up with a developer who can turn the concept into a polished product. The goal is a single code-base that runs smoothly on smartphones, tablets, and popular wearable devices. Scope • Shape the core feature set with me from early wireframes through a functional MVP. • Build clean, maintainable Kotlin/Java code that follows current Android best practices, Material Design, and responsive-layout guidelines. • Handle Play Store preparation—package signing, versioning, and listing assets. • Set up a lightweight CI/CD flow (GitHub Actions or similar) so future iterations ship quickly. • Provide basic analytics hooks and crash reporting for post-launch insight. What I’ll suppl...

Make Our MVP flatshare Marketplace Feel Premium About us We're a pre-launch real-estate/flat-share marketplace. The MVP is built and the backend is fully working and integrated.

We are Heartland Promotional Products, an established promotional products company serving business clients in Ohio. We are looking for an experienced mobile app developer to build Version 1 of a new client relationship application called Hit-Up Heartland. This is not an e-commerce app. It is not a product catalog. It is not a CRM. It is intentionally simple. Our existing clients often think of a project, question, or promotional idea while they are in meetings, traveling, or working. Instead of expecting them to remember to call later, this app gives them a simple way to notify our team in seconds. The attached PDF contains the complete project specification. Please read it before bidding. ⸻ Version 1 Features * iPhone and Android * Flutter preferred * Customer registration (on...

## Fix Two Mobile Shopify Issues — Kalles Theme / Avada Conflict Investigation **Website:** []() **Shopify theme:** Kalles **Relevant apps:** Avada and other third-party apps may be involved This project covers **two separate mobile issues**, each with its own milestone. ### Milestone 1 — £60 ## Fix Shopify Inbox on Mobile The Shopify Inbox chat icon works correctly on desktop. However, on my **iPhone 13 Pro Max**, the Inbox icon is visible and appears clickable, but the chat window does not open in either: * Safari * Chrome Other developers have sometimes been able to open it on their own devices, which suggests the issue may be intermittent or dependent on device, browser, script timing, caching or app-loading conditions. Shopify Support suggested that the pro...

I’m looking for a skilled Android developer to transform my concept, “1000askia,” into a fully functional mobile app. The first release focuses on a clean, stable build with in-app purchases implemented through Google Play Billing. Here’s what I need: • A native Android application written in Kotlin or Java, compatible with the current Android SDK. • Seamless in-app purchase flow (subscriptions or one-time unlocks, depending on what you recommend for best user experience). • A lightweight dashboard or admin configuration so I can add or adjust purchasable content without digging into code. • Polished UI that matches material design guidelines; wireframes or a quick prototype are available on request. • Source code, build instruc...

I need a straightforward way to silence every caller and texter on my iPhone except one specific contact whenever I’m in a meeting. Calls and texts from that chosen person (my wife) must still ring through; everyone else should be muted until I turn the filter off. Here’s what matters: • It must cover both calls and texts, not just one or the other. • I’m fine with either a clever use of built-in Focus / Do Not Disturb settings, a Shortcut, or a third-party app—whichever reliably delivers the result. • Extra conveniences such as quick on/off toggles, schedule presets, or small automations are welcome if they make the workflow smoother, but the core requirement is the selective blocking itself. Deliverable 1. A clear, repeatable setup (writte...

I’m assembling a real-time dashboard solution that must run smoothly on both web browsers and mobile devices. The front end will be built with modern HTML, CSS and vanilla JavaScript where appropriate, but React will drive the component logic and state management. On the back end I already have a FastAPI service in place; your task is to consume those endpoints, handle authentication with Firebase, and persist light local data through SQLite when the connection drops. The application needs to feel product-ready from day one: fast initial load, fluid charts that update live as new data streams in, and a UI that scales cleanly as we add new metrics. Efficiency and long-term maintainability matter more to me than quick hacks, so clear component structure and thoughtful API integratio...

The project revolves around building an educational Android application that acts as a “Personal Teacher” for users who want to learn Android-app concepts step by step. Think bite-sized lessons, short challenges, and quick feedback loops that make the phone feel like a private tutor. Core scope • Design and code a clean, modern Android native app (Kotlin or Java) that opens with a simple onboarding flow, then serves structured lessons on Android development fundamentals. • Integrate quizzes or mini-tests so learners can check understanding after each topic. • Track user progress locally and sync it to the cloud so they can pick up where they left off. Why location matters Face-to-face sessions will speed up architecture decisions, UI reviews, and peri...

Ich benötige kurzfristig Unterstützung, um ein Update meiner bestehenden iOS-App in den App Store zu bringen. Der Schwerpunkt liegt ausschließlich auf Release und Deployment – es sind keine neuen Features, Design-Änderungen oder Performance-Optimierungen geplant.

I’m putting together a Civil Engineering Quality-Control “Smart Ready Reckoner” and need a Flutter specialist who is physically based in Bhopal so we can meet in person when required. The entire solution will run as a mobile application and must feel completely native on both Android and iOS. Core functions I need built into the app • Material quality assessment – quick look-ups, acceptance criteria and on-site data capture. • Site inspection checklist – guided, tap-through inspections that time-stamp photos and notes. • Compliance tracking – dashboard that flags non-conformities and stores evidence for later audit. I’ll supply the civil engineering standards and the specific formulas the reckoner should reference; you conver...

On my WordPress site, built with a premium theme, the footer behaves oddly on phones held in portrait mode. When I reach the very bottom and begin to scroll up, the view suddenly snaps up to the “Our Services” <h3> heading instead of moving smoothly. I haven’t knowingly added any footer-specific custom code or plugins, so I need someone to: • trace the exact cause—whether it’s theme JS, a plugin, or rogue CSS overflow rules • correct the issue so scrolling in the footer is smooth in mobile "media portrait orientation".
