Job Title: Senior Full-Stack App Developer for Debugging, UX Fixes, and Stability Improvements Job Description: I’m looking for an experienced full-stack developer to review and refine an existing mobile/web application that is already built and functional but needs polishing and technical corrections. The goal is to identify and resolve smaller issues that affect user experience, logic flow, and overall stability. This is not a project from scratch. The application is operational, but it requires a developer who can carefully audit the system, locate inconsistencies, and implement clean fixes. Responsibilities include: Reviewing existing frontend and backend logic Fixing UI/UX inconsistencies and interaction bugs Ensuring user actions trigger the correct outcomes across the pl...

I need native smartphone users currently located in Belgium, Taiwan, Colombia, Argentina, France, Mexico, Chile, or Spain to run a round of functional tests on our dual-service mobile application. The job is straightforward: First, install the latest build on both iOS and Android devices you own. Create a new account so I can verify that user registration works smoothly in each market. Next, move on to the two core journeys—booking a ride and ordering food. Complete each flow from start to finish, including payment (we provide promo codes so you will not be out of pocket) and cancellation where relevant. While testing, note every screen, button, message, and edge case that behaves unexpectedly or feels confusing, capture screen recordings or screenshots, and collect basic device lo...

My mobile application for the general public is already coded for both iOS and Android, but it still needs a final push before launch. I’m looking for someone who can take full ownership of the finishing phase: hunt down and fix every bug, wire up eight payment gateways alongside two payout methods, connect the existing P2P + SFU server, move the backend to its new hosting environment, document the whole process, and finally publish stable builds to the App Store and Google Play. Deliverables • End-to-end functional and regression testing with issue resolution • Seamless integration of 8 payment gateways and 2 payout flows already selected in the codebase • Configuration of P2P and SFU services inside the app so real-time features perform smoothly under load &...

I’m ready to turn a fresh social-networking idea into a polished iOS app focused squarely on entertainment. The first release needs just one mission-critical feature: a real-time messaging system that feels as fluid as Apple’s own Messages. Everything else—profiles, content sharing, and any flashy extras—can wait for later iterations, so your attention can stay on building a rock-solid chat experience. Here’s what I have in mind: • Swift or SwiftUI codebase that compiles cleanly in the latest Xcode • Secure user authentication (Apple ID preferred, but I’m open to Firebase/Auth0 if you have a strong argument) • 1-to-1 and group messaging with push notifications that actually land • A lightweight, modern interface that looks at ...

I need an Xposed module that tightens security by controlling app permissions automatically, based on user-defined conditions rather than simple allow/deny prompts. The idea is to intercept any permission request at runtime, check it against a rule set (time, network, app state, or other triggers we agree on), and then grant, deny, or prompt accordingly— all without touching the original ROM. Scope – Develop the full module in Java/Kotlin for the current Xposed/EdXposed framework. – Build a compact UI for adding, editing, and importing rule profiles so users can craft conditions such as “Block camera when screen is casting” or “Allow location only on trusted Wi-Fi.” – Ensure rules apply instantly after creation and survive reboots. &nd...

You MUST be in the USA for this because these are US telco/banking etc. apps. There are 4 apps/websites you already have. I’d like you to install each one, work through the main user flows, and tell me where the experience shines and where it falls short. Your focus should stay on this area: • Functional testing – does every feature behave as expected, and are there any crashes, glitches, or confusing steps? I’m especially interested in just yes/no on the functions and comments for these 26 quick points of observation. If you have an Android/iOS phone and can dedicate a few focused hours to real-world use, I’d love to hear your insights.

I'm looking for immediate support to resolve the "Error 3 - Code Already Used" I receive when attempting to upload an AAB package to the Google Play Console. Current Situation • The app compiles and launches successfully locally. • When uploading the AAB release, the console blocks the publication, reporting Error 3 with the message "Code Already Used." What I Need 1. Quick analysis of the Gradle project to identify the cause (versionCode/versionName, signature, automatic increments, any pending artifacts). 2. Correction of the offending parameters and generation of a new signed AAB. 3. Successful upload of the release to the Google Play Console with my confirmation. I will accept the job when: • The corrected AAB is accepted without errors by the...

J’ai déjà construit mon application avec la plateforme et créé les projets correspondants dans Google Cloud Console. Il me reste à boucler les points suivants : • Configurer Google Auth côté Google Cloud Console et dans afin que la connexion utilisateur fonctionne de bout en bout (création de l’OAuth-client, SHA-1, redirections, tests réels). • Ajouter AdMob en version bannières et interstitielles, avec les IDs de placements que je fournirai (sur explication de comment les trouver), puis vérifier l’affichage sans enfreindre les politiques Google. • Exécuter une série de tests (connexion, déconnexion, flux hors-connexion, affichage publicitaire, performance ...

I need a complete mobile solution that brings every aspect of my pharmaceutical field-sales operation into one place. The app must be built end-to-end (backend, APIs and two native-feel front-ends for iOS and Android) and released to the stores under my developer accounts.

I run a U.S. service-provider account on Wayfair’s Pro app and need an extra set of fast fingers to scoop up new assembly and delivery jobs the instant they appear. The market is crowded—offers disappear in seconds—so the work is simply keeping the app open, reacting faster than the push notification queue, and tapping “claim” before anyone else does. Jobs can pop up at any hour because they’re triggered whenever a customer places an order, so I’ll schedule you in blocks that cover the busiest stretches of the day and night. While you’re on shift you stay inside the Wayfair provider app, claim everything you see for my territory, then confirm the grab by dropping a quick in-app note so I get the automatic notification on my end. No separate ...

My production Flutter app runs on both iOS and Android. Two elusive issues have slipped through testing and I need them eliminated: • On a completely fresh install the very first launch can stall on a blank screen intermittently. It never recovers until the user force-closes or restarts the app. • After the user completes OTP verification, the final signup submission sometimes fails and the flow hangs. The problem is random and difficult to reproduce on demand. Deliverables • Verified fixes for both issues on iOS and Android builds • Brief technical report summarising root cause, code changes, and test steps • Clean pull request ready for merge and release Once your patch survives my TestFlight and internal QA rounds, the job is done.

I need a seasoned ethical hacker to probe the security of my production-ready Android application. The task covers everything from installing the APK on a range of devices and emulators to hunting for flaws in authentication, data storage, network calls, and component exposure. Please treat the engagement as a comprehensive black-box review: assume no source code, no prior credentials, and simulate a real-world attacker’s mindset while remaining fully within legal and agreed-upon bounds. I expect manual exploitation to complement automated scans so that business-logic weaknesses and misconfigurations do not slip through the cracks. You are free to use tools such as MobSF, Burp Suite, Frida, JADX, or any specialised mobile framework you normally rely on, provided the findings are rep...

I’m opening a short, closed test cycle for HaazriBanao (the main attendance app) and its HB Employee companion. I need 15 reliable Android users who will commit to a full-on, 14-day trial and report back on what really matters: day-to-day usability. What you’ll actually do • Install both apps, pair them, and use them as a normal employee–manager combo would. • Pay close attention to the user interface and design, overall navigation flow, and general performance or speed hiccups. • Keep your eyes peeled for any rough edges that stop the two apps from talking to each other smoothly. • Log concise notes as you go, then submit a structured feedback sheet I’ll provide at the end of week 1 and week 2.
