Mostly React Native — it's what I know well and what I actually enjoy working with. I've shipped 42+ products across a lot of different industries: marketplaces, healthcare, fintech, booking platforms, ecommerce, B2B tools. Some of them are still running and growing. I work as a Mobile App Developer, React Native Developer, and AI Developer — and these days those three things often overlap on the same project. The AI Developer side started naturally. Clients started asking for smarter apps — chat features, recommendations, content generation, search that actually works. I learned the tools, integrated the APIs (OpenAI, Claude, LangChain), and also started building full products using AI constructors and platforms where that made more sense than writing everything from scratch. Now it's a real part of what I do, not an add-on. Click Hire or Invite React Native Developer. 📱 TYPES OF MOBILE APPLICATIONS I DEVELOP • Taxi & Transportation Apps • Booking platforms • Fitness & Health Apps • AI-based mobile systems • Security-focused iOS and Android solutions • Social media and streaming platforms — social media app, live streaming app, video streaming ecosystems • Fintech & Payments Apps • E-commerce ecosystems connected with WordPress and Shopify • Business & SaaS applications • Wearables & IoT systems — WatchOS, Apple Watch, WatchKit, smart watch integrations • Delivery and Dating Apps 🫵 WHAT YOU GET ✔️ Mobile App Development for iOS and Android — cross-platform React Native builds that actually perform, not just pass review. ✔️ React Native Developer work done properly — solid architecture, clean navigation, auth, payments, push notifications, Firebase, API integration, App Store and Google Play release. ✔️ AI Developer integration — adding AI features to existing apps, or building AI-first mobile products from scratch using AI tools, constructors, and APIs. ✔️ Mobile App Design — I work in Figma, think about flows, and care about UX. Not a designer, but I know when something feels wrong and I'll say so. ✔️ Honest communication — I'll tell you what's realistic, flag problems early, and keep the project moving without needing to be chased. 🔥 WHAT I'VE ACTUALLY BUILT ✔️ 42+ apps delivered as a Mobile App Developer — from quick MVPs to multi-year product partnerships. ✔️ React Native Developer across healthcare, fintech, logistics, wellness, ecommerce, social, and B2B — most categories covered at this point. ✔️ AI Developer projects: AI integrations, AI-powered Mobile App features, and full AI app builds using modern platforms and tools. ✔️ Products that kept users: better retention, fewer drop-offs, smoother flows — that's what matters after launch. 🚚 WHERE I HELP ✔️ New Mobile App Development — MVP to production as a React Native Developer. ✔️ Existing apps — audit, rebuild, or improve what's already there. ✔️ AI Developer work — integrate AI into your app, add smart features, or build something AI-first from the ground up. ✔️ Anything cross-platform — one React Native codebase, iOS and Android, done right. 🏆 WHAT I'VE WORKED ON ✔️ Marketplace apps — listings, search, chats, bookings, payments, reviews, maps, admin panels. ✔️ Healthcare and wellness — onboarding, profiles, appointment flows, reminders, HIPAA-aware builds. ✔️ AI-powered products — AI Mobile App Development with real features: chat, recommendations, smart search, content generation. ✔️ Ecommerce and subscriptions — In-App Purchases, product catalogs, checkout flows, retention mechanics. ✔️ Business tools — role-based dashboards, approvals, reports, notification systems. ⚒️ HOW I WORK ✔️ React Native is my primary tool as a Mobile App Developer. I know it well, I use it daily, and I don't oversell what it can or can't do. ✔️ As an AI Developer I pick the right approach for the project — sometimes that's an API integration, sometimes it's an AI constructor, sometimes it's a lightweight custom build. ✔️ Firebase, Node.js, REST APIs, User Authentication, In-App Purchases — the backend side is covered. ✔️ I'm involved from discovery to release. I'll ask the questions that matter early so we don't redesign things at the end. ✔️ After launch I'm available — bugs, improvements, new features, whatever comes next. 📩 READY TO START ASAP

She is a genuine pleasure to work with every day." ✅ "Incredibly good freelancer. One of a kind in her skills and in kindness.

Knowledgeable freelancer, clear communication, set right expectations, great input along the way and very respectful of my workstyle. Kudos to her!

A++ !!! is how I want to end my feedback." ✅ "Valentyna is great professional.

She made everything about my vision come to life. Anything that I asked her to do for our designs, she always made it happen!!! She was quick to respond and amazing at communicating! She is such a pleasure to work with and I will definitely be working with her again!" – Adam Kovacsik, Founder & CEO at AlyveRx “I directly observed Julia perform and deliver exceptional, divine-like work... on a routine basis. What separates Julia is her ability to zoom out on complex problems... properly gather all essential and non-essential information... consider and weigh that information to rank all possible courses of action... and then zoom back in with the most ultra-precise and airtight solutions. There's the old saying, "If you want something done right, do it yourself"... but Julia makes this statement false. Let her help you... and the task will get done far better than if you did it yourself." – Richie Gelman, Founder & CEO at Billboards “I had the pleasure of working closely with Julia on the development of the Orovera app, particularly focusing on the iOS and Android financial keyboard feature. As our designer, Julia consistently impressed me with her creativity, attention to detail, and dedication to delivering high-quality work." – Mykola Gavryshchuk, Founder & CEO at Orovera 𝙈𝙔 𝙎𝙆𝙄𝙇𝙇𝙎: UX · UI · Design Leadership · Sketching · UX Research · User Interviews · User flows · Wireframes · Mockups · User testing · Data analysis · A/B Testing · Communicative · Detail oriented · Figma · Adobe Photoshop · Strategic thinking · Design Systems · Style Guides · Cross-functional Collaborations 𝙆𝙀𝙔𝙒𝙊𝙍𝘿𝙎: UI/UX Design · Web Design · UX Design · UI Design · Web & Mobile Design · Responsive Web Design · Website Redesign · Landing Page Design · SaaS Design · Dashboard UI · Mobile App Design · Marketplace Design · Website Wireframing · Website Prototyping · Wireframing · Figma, Adobe XD · Interaction Design · User Flow · Clickable Prototype · Prototyping · UX Research · Usability Testing · Design System · Design Thinking · Visual Design · Mobile Web Design · Frontend UI Design · User Interface Design · Desktop App Design · UX Strategy · Journey Mapping · Competitive Analysis · Creative Web Design
