Bolt, Lovable, Cursor, and Claude Code get you 70% of the way there. The last 30% is where I live. I finish and harden AI-built apps, and I build production AI from scratch. If your app demos well but falls apart once live users hit it, saves that don't stick, a data model that buckles at scale, security holes you can't see, that is what I fix. I also build the AI itself: phone and voice agents that book appointments, agentic workflows, and full Supabase and Stripe backends. I know where these tools break because I clean it up for a living. One Lovable app owner described it as "fix one thing and five break." That traces straight to the generated backend, the data model and the save logic, not the features. Solidify that and the cascading bugs stop. Recent work: โ€ข AI phone receptionist for a service business. It answers and texts customers in the owner's voice, books appointments, and writes them straight into their Jobber CRM: client, job, and visit created automatically, nothing re-keyed in the morning. Built on Twilio, a voice agent, and a knowledge base of the owner's own playbook. โ€ข Took a Lovable-built MVP to production: a creator marketplace that generated 150M TikTok views and paid out $15,000 to 200+ creators. Stripe Connect plus PayPal payouts, TikTok API, multi-tenant row-level security. Client: "Andrew got my MVP over the line and helped bring my vision to life." โ€ข Overhauled a production voice agent for a hospitality venue handling live booking calls, then built one source of truth so non-technical staff edit a single page and both the text bot and the voice agent update from it. โ€ข Audited a Supabase app and found 14 significant bugs, including booking records any logged-in user could read and missing security rules. Every finding came with the specific fix and why it matters. โ€ข Stabilized a Lovable carousel app's edit and save flow so edits stick and it holds well past its first users. How I work: โ€ข Fixed price per milestone. You know the cost up front, there is no open meter, and you only move to the next piece once the current one is done and working. โ€ข I use Claude Code and Cursor to ship 2-3x faster, and I verify everything the AI touches. โ€ข Straight about tradeoffs and limits up front, especially on security work. โ€ข I explain technical decisions in plain English. Most of my clients are not developers. Stack: Supabase (Postgres, RLS, Auth, Edge Functions, Vector/RAG), Stripe (Connect, Subscriptions, webhooks), React, Next.js, React Native, TypeScript, Node.js, voice agents (ElevenLabs, Retell), Twilio, OpenAI and Claude APIs, n8n, Vercel. Background: 10 years full-stack across health tech, edtech, and fintech. Taught two web development bootcamps. Top Rated, 100% Job Success, $60K+ earned. If you built something with AI and it is almost there, send me a message. I will tell you straight what it needs, and what it does not.

React Native developer hiring guide

React Native developers build cross-platform mobile apps from a single codebase, helping businesses launch on both iOS and Android without maintaining separate development teams. From startups shipping their first MVP to enterprises scaling internal tools, a skilled React Native developer can accelerate delivery timelines and reduce long-term maintenance costs.

What does a React Native developer do?

React Native developers build cross-platform mobile applications for iOS and Android using a single JavaScript or TypeScript codebase. They create native-feeling interfaces, connect apps to back-end services, and optimize performance across devices, making them a practical choice for businesses that want to reach mobile users on both platforms without doubling development effort.

Common responsibilities for React Native developers include:

  • Building cross-platform mobile apps with one codebase for iOS and Android

  • Optimizing app performance through debugging, testing, and load time improvements

  • Integrating APIs, payment systems, and cloud services like Firebase and AWS

  • Implementing UI/UX designs using reusable native components

  • Preparing apps for deployment on the App Store and Google Play

How to hire a React Native developer on Upwork

Whether you need a full app built from scratch, performance optimization for an existing codebase, or ongoing mobile development support, the process starts with a clear job post and ends with a secure working agreement. These steps walk you through finding and hiring the right developer.

Step 1: Post a job

A strong job post helps React Native developers quickly determine whether their skills, experience, and availability match your project requirements.

  • Specify your target platforms, such as iOS, Android, or both, along with any device-specific requirements

  • Note whether you're building a new application, extending an existing codebase, migrating from another framework, or maintaining a live app

  • Include design assets, wireframes, prototypes, or UI requirements if available

  • Describe required integrations such as APIs, payment processors, authentication systems, analytics tools, push notifications, or cloud services

  • List technologies and libraries relevant to the project, such as TypeScript, Redux, Firebase, GraphQL, Expo, React Navigation, or native modules

  • Share expected user volume, performance requirements, offline functionality, and app store deployment needs if applicable

  • Include your budget, timeline, and preferred collaboration style, whether that's async updates, daily standups, or milestone-based check-ins

  • Draw ideas from this React developer job description as a starting point

Use our Job Post Generator, powered by Umaโ„ข, Upwork's Mindful AI, to speed things up. Describe what you need in a few sentences, and Uma will draft a job post tailored for React Native developers that you can review and customize. 

Step 2: Evaluate candidates

Once proposals start coming in, focus on identifying developers with experience building and maintaining React Native applications similar to yours.

  • Use Uma to conduct instant interviews, generate candidate shortlists, and compare applicants side by side based on your project requirements

  • Review portfolios for published mobile apps, cross-platform projects, and applications with functionality similar to your project

  • Look for experience building and maintaining apps for both iOS and Android environments

  • Evaluate experience with your required technologies, including TypeScript, Redux, Firebase, GraphQL, Expo, push notifications, authentication, and third-party integrations

  • Review examples of app performance optimization, app store deployment, and ongoing maintenance work

  • Check Job Success Scores (JSS), client feedback, and talent badges such as Top Rated, Top Rated Plus, or Expert-Vetted

  • Review client feedback to look for evidence of strong communication, reliable delivery, and successful long-term project support

Step 3: Interview top choices

Interview shortlisted candidates to evaluate their technical expertise, development process, and ability to support your application's requirements.

  • Schedule and conduct interviews through Upwork Messages and review transcripts and summaries afterward to compare candidates efficiently

  • Ask about their approach to application architecture, state management, performance optimization, and cross-platform development

  • Discuss experience handling app store submissions, app store rejections, updates, and release management

  • Explore how they approach debugging, testing, crash monitoring, and maintaining application stability across devices

  • Review experience integrating APIs, payment systems, authentication services, analytics platforms, and cloud infrastructure

  • Ask how they handle native device features such as camera access, geolocation, push notifications, background processing, and offline functionality

  • Consider a small paid assessment, such as implementing a feature or reviewing an existing codebase, to evaluate practical problem-solving skills

  • Use React developer interview questions as a starting point and tailor follow-up questions to your project's technical requirements

Step 4: Agree on scope and begin work

When you've selected a React Native developer, align on technical requirements, deliverables, and project milestones before development begins.

  • Finalize the project scope, deliverables, timeline, budget, and communication expectations in a formal hourly or fixed-price contract

  • Define milestones around major deliverables such as application architecture, core features, testing phases, beta releases, app store submissions, and production deployment

  • Confirm responsibilities for development, testing, bug fixing, deployment, maintenance, and post-launch support

  • Align on coding standards, documentation requirements, source code ownership, and repository access before work begins

  • Share design assets, API documentation, technical specifications, credentials, and project requirements through the contract workroom

  • Use messaging and the contract workroom to manage communication, files, feedback, and progress updates in one place

  • Take advantage of identity verification, Hourly Payment Protection, and milestone funding tools to support a secure engagement

  • Track progress against milestones and review deliverables throughout development to ensure the application stays aligned with project goals and launch requirements

FAQs about React Native developers

Frequently asked questions

Is hiring a React Native developer worth it?

For most businesses building mobile apps, yes, React Native's single-codebase approach means you're maintaining one project instead of two, which can significantly reduce both development time and long-term maintenance costs. Developers and hiring managers in online communities frequently point to faster iteration cycles and simpler updates as key advantages, especially for startups and mid-sized companies shipping their first cross-platform product.

Should I hire a freelance React Native developer or a dedicated team?

A freelance React Native developer is a strong fit for feature builds, bug fixes, and short-term projects where you need to move quickly without long-term overhead. A dedicated team may be a better choice for large-scale, ongoing app development that requires coordinated front-end, back-end, and QA work.
