Working with Oleg and Olearis team has been awesome. We just wrapped up the first milestone, and honestly, everything went super smooth. Super happy with the result so far, and I’m definitely looking forward to coming back soon for the next stage of development with them. Highly recommend!

Mobile App Development for AI Fitness Coach (Flutter / iOS / Android MVP)
Oleg is amazing to work with. I am so happy I found a mobile developer who really cares about the product.He helped me refine the product idea so it is competitive in the market now. We talked a lot and even fixed the Figma design because Oleg during our first meetings noticed details that other designers and consultants missed. I started with a small scope first, and everything was fast, on time, and followed our plan.
I will definitely continue my mobile app development with Oleg and Olearis later. It is rare to find someone so professional who understands flutter app development so deeply. I am very glad such attentive developers exist.

iOS App Verification and App Store Submission Help
Oleg is a lifesaver! I had a legacy Ionic app that faced serious compatibility issues with the current App Store requirements. While most would have given up, Oleg didn't. He found a way to adapt the old codebase, navigated all the technical hurdles, and successfully got the app published. He is incredibly persistent, diligent, and a true expert. If you have a complex technical challenge, Oleg is the person you want in your corner.

I'm Oleg - founder of Olearis (a mobile dev studio) and a hands-on mobile app developer. I help founders, startups, and product teams turn an idea into a Flutter or React Native app that ships on time, keeps users, and moves the business. As a flutter developer and full stack developer, I own the whole path from idea to App Store, so you get one accountable partner instead of five contractors. Mobile App Development, done right, is how a rough idea becomes real traction.
❗️ What that looks like in numbers:
1M+ users and a 4.8⭐️ rating — that's where UpLife landed after we scaled it with Flutter App Development and AI Development.
10M+ users — that's how far Parlor grew as a cross-platform Mobile App Development build.
$2.88M raised and 450K+ users — that's what GoFrendly reached with the right Mobile App Development partner.
🎯 Where I create the most value
▪️ Flutter App Development, done right — As a flutter app developer I ship clean, maintainable code and scalable architecture: smooth 60 FPS UI, role-based access (RBAC), user authentication, push notifications, in-app purchases and subscriptions, chat / messaging, analytics, and full App Store / Google Play launch. Flutter App Development is cross-platform, so you ship once instead of paying to build the same app twice. Across 400+ projects, flutter mobile app development with native depth in Swift (iOS) and Kotlin (Android) delivers production-ready apps, not demos. Whether you need flutter mobile app developer support for a fresh build or a rescue, Flutter App Development scales from a 2-week MVP to a multi-year product.
▪️ AI Development that earns its place — As an ai developer I build AI Development features that bring users back: AI assistants, smart onboarding, personalization, recommendations, image recognition, and context-aware journeys. Practical AI Development also means document processing, chat-based AI (ai chatbot developer work), and job application automation. If you want an ai software developer who ties AI Development to retention and revenue — not a trendy add-on — that's exactly what I do.
▪️ Full-stack support — As a full stack developer I cover Node.js, Python, FastAPI, Firebase, REST APIs and api development, plus cloud functions, admin dashboards, and role-based access. As a web developer I handle the surrounding web design, web-to-mobile conversion, and admin panels. React and react developer work on the front end, react native on mobile — fewer handoffs, faster decisions, and clean code across the stack.
📲 A few products I've shipped as a mobile app developer
✔️ UpLife — mental health app with an AI assistant & therapy recommendations. 1M+ users, 4.8⭐️
✔️ Parlor — social audio platform, 10M+ users
✔️ GoFrendly — social network for women. 450K+ users, $2.88M raised
✔️ Notate — secure productivity app trusted by Bank of America, Citibank & 80+ companies
✔️ Mila Cares — connected HEPA air purifier app. 50K+ users, $1.58M raised
✔️ Fillrr — AI-powered document app, 4.9⭐️
✔️ Photofy — content creation app, 100K+ users, 4.9⭐️

🤝 Why founders keep coming back
I treat your budget like my own and your deadline like a launch I'm personally on the hook for. As a mobile app developer and flutter developer I don't vanish after App Store approval - I stick around for real users, real reviews, real iteration. 90%+ of my work is repeat clients and referrals. If a flutter developer or mobile app developer once handed you a demo and disappeared, Mobile App Development that actually ships is the gap I fill. Need a full stack mobile app developer or a react native mobile app developer for the next build? Send me the details and I'll tell you honestly what it'll take.
If you need Flutter App Development, React Native, full stack developer support, or AI Development from someone with a proven track record of shipping real products at scale, message me. Mobile App Development is what I do every day - let's make yours one of the wins.
