I need someone to ensure the AI tools on my app function correctly and then download the app from atoms.dev and Xcode. The goal is to prepare it for submission to the Apple Store. The ideal candidate will have experience in AI tool integration and app development, particularly with iOS platforms.

Hi, I have spent $243,000 on UpWork and I am easy to work with because I am a consultant myself. Check out how other people rate me on this platform. I have been building a react native app for about a year now and I need an expert react native developer to do a code review. I was thinking you could take 10 hours to do a deep dive on my app and write up all the issues you see so I can fix them. I developed everything myself but I need another set of eyes on this. Backend is supabase.

You are going to be building an iOS trading app that has to be EXCEPTIONALLY high quality (in it's feel), simple in design, and has a UI that has an engaging feel -- like it buzzes upon certain buttons. I need you to submit examples of your work of live trading apps or other sleek apps like Cal AI. You need to have flawless English, be a fast developer (English), Swift-native, etc. Do NOT use AI to respond

I have a working small React Native/Expo app (codebase provided) that needs help getting set up and running. This is NOT a build-from-scratch job — the core app is already written (screens, navigation, UI). I need help with configuration, testing, and deployment. What I need: Set up a Firebase project (Firestore) and connect it to the app Get the app running locally via Expo Go so I can test it on my own phone and a few family members' phones Set up a Firebase Cloud Function that sends an SMS via Twilio when a specific event happens in the app (code for this is already drafted, needs to be deployed and tested) Walk me through the process on a call or via screen-share so I understand what was done and can maintain it going forward (Optional, separate scope) Help prepare and submit the app to the Apple App Store and Google Play Store once I've validated it with my test group What's already done: Full app code (screens, navigation, components) Firebase and Firestore integration code (needs a live Firebase project connected) Cloud Function code for the SMS alert feature (needs Twilio account + deployment) A README with setup steps What I'm looking for in a freelancer: Experience with React Native / Expo and Firebase Comfortable explaining technical steps in plain language — I'm not a developer Budget: Fixed price. Happy to discuss hourly if scope runs longer.

Senior Full-Stack Flutter Developer (AI Platform) We're looking for a Senior Full-Stack Flutter Developer to lead development of a production-grade AI-powered web and mobile application. This is a long-term opportunity for an experienced engineer who can own architecture, development, and deployment. Responsibilities Build Flutter applications for Web, iOS, and Android Design scalable backend services and REST/GraphQL APIs Develop data import, ETL, cleanup, and normalization pipelines Integrate AI/LLMs (OpenAI, Claude, or similar) into production workflows Build analytics dashboards and AI-driven insights Architect PostgreSQL databases and cloud infrastructure (AWS/GCP/Azure) Optimize performance, security, and scalability Deploy and maintain production applications Requirements 7+ years of software development experience Expert in Flutter (Web & Mobile) Strong backend experience (Node.js, Python, Go, or similar) PostgreSQL and API design expertise Experience building ETL/data pipelines Production experience integrating AI/LLMs (OpenAI, Anthropic Claude, etc.) Hands-on experience with Claude Code and Claude Design for AI-assisted development workflows Experience using modern AI coding tools (Claude Code, Cursor, GitHub Copilot, Windsurf, etc.) Cloud deployment experience (GCP, AWS, Azure) Position is available immediately Must be available to work between 8 am - 5:00 pm + M-F

Scope of work (fixed) 1. Firebase setup — create/configure the project under my firm-owned account, enable Authentication and Firestore. 2. Database structure — create the collections per my spec: users (first name, last name, email, phone, consent, A-number, language, created date), a recipients subcollection, and an alerts collection. 3. Security rules — users can read/write only their own data; alerts written via Cloud Function only. Data minimization matters (see note below). 4. Wire the existing registration screen to save name / phone / email to users on submit (consent-based; the screen and consent UI already exist). 5. In-app account deletion — delete the user's Firestore data + Auth record (Apple requires this). 6. SOS engine — a Firebase Cloud Function that sends SMS via Twilio when SOS is pressed: text each saved recipient + notify the firm, include the user's captured GPS location as a map link, and log an alerts record. Wire the app's existing "Alert my people" button to call it and pass location. 7. Leads dashboard — a simple authenticated web page listing registered users (first name, last name, email, phone, sign-up date) with CSV export. List + export only; no CRM features needed. Out of scope: any UI/screen design, navigation, or content — all done. Encounter audio/video recording (v2). Android (later). What I provide • The finished FlutterFlow project (I'll grant access) • A detailed build spec (data model, cloud function outline, permissions, App Store requirements) • All content and branding • My Apple Developer + Firebase accounts (firm-owned)Required experience • Firebase: Firestore, Auth, Cloud Functions, security rules • Cloud Functions calling Twilio for SMS — this is the critical skill • Integrating a backend into an existing FlutterFlow project • Understanding of iOS constraints around messaging (see note) Critical technical note (please address in your proposal) Please confirm you understand that iOS cannot send SMS silently in the background, so the SOS messaging must be dispatched server-side (Cloud Function → Twilio), not from the app directly. Proposals that describe the app texting contacts directly will not be considered. About the users (please read) Users are often undocumented or mixed-status people. Data minimization, encryption, and transparent consent are requirements, not options. No covert or undisclosed data collection. I need someone who takes this seriously. To apply, include 1. Links to 1–2 apps where you integrated Firebase/Twilio (App Store links if possible) 2. A brief description of a Cloud Function you wrote that called an external API (Twilio or similar) 3. Your fixed-price quote and timeline for the scope above 4. Any questions about the spec

I’m looking for an experienced full-stack developer to help improve an existing React Native mobile app and build a modern web platform for the same product. The mobile app is already live on the App Store, and I’m looking to modernize the UI/UX, improve the overall user experience, and add new features over time. Alongside the app, I need a responsive website where users can learn about the platform, create accounts, subscribe, and manage their information through a secure dashboard. The platform is focused on amateur basketball leagues and will continue to grow, so I’m looking for someone who can build with scalability and maintainability in mind rather than simply delivering a one-time project. I’m looking for a developer who: * Has strong experience with React Native and modern web development * Is comfortable working with Firebase and subscription-based applications * Writes clean, scalable, well-documented code * Uses modern AI development tools (such as Cursor, Claude, GitHub Copilot, etc.) to work efficiently * Can communicate clearly and contribute to technical decisions This has the potential to become a long-term working relationship as the platform continues to expand. My goal is to find someone who can initially build the next phase of the product and potentially continue as the technical lead as we grow.

We’re looking for a talented and reliable UI designer to become our go-to designer for several upcoming projects and future product work. This is UI-focused work — we are not looking for UX research, user flows, or product strategy. We will provide the requirements, functionality, and direction. Your job is to turn that into clean, polished, professional interfaces. We have multiple projects coming down the pipeline across web applications and mobile apps, and we’d like to build a long-term relationship with one designer who can learn our visual style and work with us consistently. The workload will be part-time and project-based, but responsiveness and reliability are very important to us. What You'll Work On - UI design for web applications - Mobile app UI for iOS and Android - New screens and features for existing products - High-fidelity designs based on provided requirements - Responsive desktop and mobile layouts - Reusable components and consistent design systems - Improving and modernizing existing interfaces - Developer-ready Figma files and handoff - Occasional landing pages and other product-related designs What We're Looking For The ideal person: - Has a strong portfolio of modern web app, SaaS, and mobile UI - Is highly proficient in Figma - Has excellent visual design skills, including typography, spacing, hierarchy, layout, and consistency - Can take requirements, rough sketches, or existing screens and turn them into polished UI - Designs with development and implementation in mind - Creates clean, organized Figma files and reusable components - Can follow an existing visual style while also improving it when needed - Communicates clearly and is responsive - Can work independently and turn around revisions efficiently - Has availability for ongoing part-time work - Is interested in becoming our long-term UI designer - Experience designing B2B & B2C SaaS, dashboards, operational software, or data-heavy applications is a strong plus. How We Work We will generally provide the functionality, requirements, and direction for each project. We need someone who can take that information and translate it into a professional, modern, and highly polished UI. Some weeks may have more work than others, so this isn't necessarily a fixed number of hours every week. We're looking for someone who can work with us consistently as projects arise and be responsive when we need new designs or revisions. There is potential for significant ongoing work for the right person. To Apply Please include: - Your portfolio, with a focus on web application and mobile app UI. - 2–3 examples that best demonstrate the quality of your UI work. - Your general weekly availability. - Your typical response and turnaround time. - Your hourly rate. - Whether you personally complete the design work or work as part of an agency/team. Please start your proposal with the word “FIGMA” so we know you read the full posting. We are looking for one dependable designer we can continue working with across multiple projects, not someone for a single one-off project.

I am creating an app that I need a great coder that understands GUI, in app purchasing, and basic puzzle game elements. It has a format similar to duolingo, with an avatar creator and some chatgpt integration. I have a base mock up on replit but need it reprogrammed to be able to end up on the app store.
