    I need a reliable Flutter developer to give my existing mobile app a quick visual polish and clear out a few lingering bugs. The priority on the design side is refreshing our graphics: the main app icon as well as several background images need to be replaced with new assets I will supply. Please ensure they render crisply on every common device density and appear correctly in both Android launcher and in-app screens. Alongside the graphic swap, I’d like you to track down and solve the minor issues users have reported (occasional crashes on login and a misaligned toolbar on tablets). No new features are required—just clean, well-commented fixes that keep the current functionality intact. Deliverables • Updated app icon integrated into the build • All specified b...

    I have a RecyclerView driven by a LinearLayoutManager. Card taps are currently picked up through an OnPress handler, and I already keep the underlying data in a ViewModel. The problem is simple: when a user opens a detail screen from any card and then presses the back button, the list always jumps back to the very top instead of revealing the card they originally tapped. I need the list to remember its exact scroll position so that returning feels seamless. You’re free to solve it however you feel is cleanest—saving and restoring the layout manager state, using the Navigation component’s back-stack handling, or any other proven method—as long as: • the previous scroll position is restored every time, • orientation changes don’t break the fi...

    I’m looking for a developer who can build a clean, intuitive application devoted entirely to personal note-taking. My goal is a distraction-free space where I can quickly jot ideas, organise them in a logical structure, and retrieve them just as easily. Platform choice is flexible—desktop, mobile, or a web-based hybrid—so feel free to recommend the stack you think suits a personal workflow best. Key considerations • Speed and simplicity: the interface should load fast and stay out of the way while I write. • Local data ownership: notes must remain private, with any optional cloud element clearly explained and under my control. • Future-proof code: well-commented, modular, and easy for another developer (or me) to extend later.

    I need a clear, actionable strategy for push notifications in my fashion shopping app. The focus is on NEW ARRIVALS alerts that fire the moment a user browses a specific category—no delays, the message must go out immediately. Here’s the flow I want mapped out: • Identify the in-app event when a customer lands on or scrolls through a category page. • Capture the event and trigger a personalised “New Arrivals” notification in real time. • Outline the copy style, ideal character count, imagery guidelines and suggested deep-link destinations so the alert feels helpful, not spammy. • Recommend the technical setup (e.g., Firebase Cloud Messaging, OneSignal, or another SDK you trust) including segmentation tips, rate-limiting safeguards, and an...

    I’m building a loyalty card application that must run natively on both iOS and Android. The core experience is straightforward: users create an account, collect points with every purchase, and exchange those points for rewards they can actually use. Timely push notifications should remind them when they are close to unlocking a benefit or when a special promotion goes live. I already have the screen flows and wireframes sketched out; what I need from you is complete, production-ready code plus basic analytics hooks so I can see how people move through the app. Feel free to choose the most efficient cross-platform stack (React Native, Flutter, or similar) as long as performance remains near-native and the final build passes App Store and Play Store review. Key deliverables: Fully fun...

    The core screens and logic for my iOS app are already written and sitting in a public Replit workspace. What remains is the last-mile engineering work: • Implement phone-number sign-in with Twilio one-time-password (OTP) verification, wired into the existing authentication flow. • Polish and complete any remaining Swift / SwiftUI code so every button, API call, and screen behaves exactly as described in the repo’s README. • Configure production-ready certificates, provisioning profiles, and an App Store listing, then push the final build through TestFlight and on to public release. Everything you need—designs, user stories, current source, and a checklist of edge cases—is already documented in the project wiki. The app targets the latest iOS version, ...

    We are looking for a developer to build or customise a cost-effective, private enterprise communication platform for a small company (20 to 200 users total). It does not need to be an exact clone of WhatsApp—a system inspired by WhatsApp, Discord, or similar messaging platforms works well, provided it covers our core access, permission, and monitoring requirements. Budget & Codebase Requirement: - Budget-Conscious: This is for a small user base (up to 200 users), so we are looking for a lean, affordable solution, not a massive enterprise budget project. - Code Maintenance & Ownership: We are not interested in generic off-the-shelf CodeCanyon templates. We prefer freelancers/agencies who have their own clean, proprietary messaging source code/framework that can be customised ...

    I’m building “A.S Task Earner”, an Android application where users complete light-weight activities—primarily simple clicks, quizzes and other mini games—to collect coins they can later withdraw to a UPI account. Core user flow • Multi-method sign-in via Firebase Authentication (email + password, Google, and phone) • Home dashboard that shows a real-time task list served from Firebase Realtime Database • Coin wallet with live balance, withdrawal request form, and withdrawal history • Profile page plus FCM push notifications for new tasks, approvals, or general updates Admin console A separate web panel (any modern JS or Flutter web stack is fine) must let me: – View, search, and manage every user – Add, edit,...

    Android Roadside App Bug Fixes
    13 ore left
    Verificato

    Our live roadside-assistance suite—one consumer app and one tow-driver app, now topping 40 k installs—needs an experienced React Native engineer to squash the remaining Android-side bugs. Current pain points to resolve: • Driver registration occasionally throws false error messages. • Admin panel (cPanel) cannot reliably create, edit, or delete driver accounts in the database. • Call-matching logic sometimes fails to assign the nearest available driver. • A handful of driver account-setting screens are not saving changes properly. I have staging keys, Play Console access, and a transparent Git history ready for you. Once these fixes are confirmed in production, the role will expand into ongoing ownership of the codebase, including an AI-powered...
