จาก 56,922 รีวิว ลูกค้าให้คะแนน Mobile Developers 4.9 จาก 5 ดาวProject Brief: Universal Vehicle Emergency & Assistance Platform (Android + iOS + Admin Panel) Project Overview I am looking for an experienced Flutter development team to build a professional, scalable, and production-ready mobile application called Vehicle SOS. The vision is to create a 24/7 on-demand roadside assistance platform where any vehicle owner can instantly request emergency help anywhere in the country. This is not just a mechanic booking app. It is a complete vehicle assistance ecosystem that connects users with verified mechanics, fuel providers, towing operators, battery services, tire shops, locksmiths, and emergency roadside support through a single platform. The application must be designed with scalability in mind so it can expand internationally in the future....
I’m ready to turn my concept “Sardar Ji” into a full-featured social gaming experience for both Android and iOS. The core is a 4-player Ludo table, and I want players to choose between Classic, Quick, and Tournament modes while chatting in real time through in-game voice. Authentication must feel effortless, so please wire it to Mobile-number OTP and Google Sign-In only. Once inside, every player creates a profile, adds friends, and climbs a global leaderboard fed by a daily-coin bonus, streak rewards, and other retention hooks managed in Firebase. Visual identity is Punjabi at heart: bright Orange, Blue, and Gold accents, with avatar items such as turbans, kurtas, sunglasses, and matching frames. The entire UI should switch cleanly between Punjabi and English. Push...
iOS App Development Brief: Revaliday 1. Project Objective We are looking for an iOS developer (Swift/SwiftUI) to build the native mobile client for Revaliday, a real-time multiplayer medical quiz game. Current Project State: The platform is completely functional. We already have a fully operational HTML/web client, and the backend ecosystem—powered by a custom Java WebSocket signaling server—is 100% finished. The AI matchmaking, round management, and game logic are handled entirely server-side. Your Role: Your task is solely to build the native iOS interface and connect it to our existing WebSocket (WS) server. You will not need to write any game logic. The app acts as a lightweight client that sends user interactions and updates the UI based on incoming JSON payloads. 2. Co...
I’m looking for a developer who can deliver a polished Android application focused on Forex trading. The core features I need are: • User onboarding: simple sign-up and login screens backed by secure authentication. • Wallet functions: deposit and withdrawal flows integrated with Airtel Money, plus a clear display of current account balance. • Trading module: ability for users to place and manage basic Forex trades (no live price feed required at this stage). • Clean, intuitive interface that feels familiar to anyone who has used a mainstream finance app. • Solid security practices—encrypted data in transit and at rest, input validation, and protection against common mobile threats. You’re free to choose the tech stack, as long as it fol...
We are developing an enterprise-grade SaaS platform called ID Mitra, an ID Card and Attendance Management solution used by schools, colleges, universities, corporate organizations, and government institutions.

We are looking for an experienced developer who has worked with Computer Vision, AI inference, image processing, and Flutter performance optimization. Project Objective Develop a high-performance Android module that automatically captures, validates, enhance...
I’m building a small prototype in Unity 6000.4.0f1 and need a fully physics-based locomotion system that relies solely on the player’s hands. The experience is being tuned first for Oculus Quest, so everything has to feel light, responsive and run smoothly on mobile hardware, yet remain engine-agnostic enough to drop into other PC-VR projects later. Core requirements • Hand-driven movement only – no thumb-stick or artificial slide. • Natural climbing and mantling: the player should pull, swing or shimmy exactly where their hands move with zero bounce or jitter. • Full-hand grabbing for tools, weapons and any other interactive props. When a hand is inside the radius of an optional grab point it should snap cleanly; otherwise it must grip wherever it l...

My LG G8X has been stuck on the lock screen since May 2023 after I forgot the password during exam season. I need a reliable way to regain full access without losing any of the photos, notes, contacts, or apps stored on the handset.

I’m building a straightforward voice-only calling app dedicated to Android. The core requirement is rock-solid one-to-one voice communication, so there’s no video feed or chat module to worry about—just clean, low-latency audio calls.

Think of an experience as seamless as a standard dialer but inside its own sandboxed app. What I need from you: • Full Android Studio project (Kotlin or Java) with well-commented source code • Functional APK for testing on Android 10+ devices Acceptance: • Phone verification must complete within two steps and fail gracefully on bad codes • Voice connection ...

I need an Android application built specifically for my chartered accountancy firm so that we can manage clients more efficiently. The single, non-negotiable feature for this first release is secure document sharing. Each client should be able to log in, upload or download files (PDF, Excel, images, etc.), and receive a push notification when new documents are available. On my side, I want a simple dashboard to assign files to individual client profiles and track whether they have been viewed. Security and ease of use are my top priorities, so please incorporate best-practice encryption for data in transit and at rest, along with fingerprint or face unlock support if the device allows it.

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 want to turn every visit on a phone or tablet into a smooth, fast, and frustration-free experience. Desktop already works well; the gap is squarely on mobile responsiveness. Layouts occasionally break, tap targets drift, and first interaction feels a beat too slow. The goal is to tighten those areas so overall user experience noticeably improves. Scope of work • Audit the current mobile view with tools such as Lighthouse or PageSpeed to pinpoint layout shifts, blocking assets, and sluggish elements. • Refactor styles, scripts, and images so each page scales cleanly from the smallest screens upward—modern media queries, flexbox/grid, and lightweight assets only. • Supply a short before-and-after report that shows measurable gains in mobile Core Web Vitals (LCP,...
