Senior Flutter & React Native Developer 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.

❗️ UpLife hit 1M+ users and a 4.8⭐️ rating after we took it from idea to scale with Flutter App Development and AI Development. Parlor scaled to 10M+ users. GoFrendly raised $2.88M. This is what the right Mobile App Development partner converts into - real traction, real revenue, real users.

👋 I'm Oleg - founder of Olearis (mobile dev studio) and a hands-on Mobile App Developer. I build apps that actually ship, get used, and survive after launch - Flutter and React Native, usually with AI agents inside.
I'm a founder and mobile product engineer, not just a coder for hire. I've launched my own apps, so I understand the founder side: budget pressure, unclear scope, investor expectations, App Store deadlines. I'll tell you when something is a bad idea before it burns your budget.

🎯 Where I create the most value:
▪️ Flutter App Development, done right — As a Flutter developer and Flutter app developer I ship clean architecture, smooth 60 FPS UI, native integrations, payments, push, analytics, and full App Store / Google Play launch support. Cross-platform Mobile App Development means you ship once instead of paying to build the same app twice. When a product needs native depth, I also work in Swift (iOS) and Kotlin (Android).
▪️ AI Development that earns its place — AI assistants, smart onboarding, personalization, recommendations, image recognition, and context-aware journeys. I build practical AI Development features like document processing and job application automation. A good AI agent is often the reason users come back — not just a trendy add-on.
▪️ Full-stack support — as a full stack developer I cover Node.js, Python, FastAPI, Firebase, REST APIs, and API development, plus cloud functions and admin dashboards. As a web developer I also handle the surrounding web design and panels, so there are fewer handoffs and faster decisions.


🧠 Industries where I go deep: Mental health & wellness apps, where trust, privacy, and calm UX matter as much as code and productivity apps with habit loops, reminders, streaks, and smart automations.

📲 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 scaled to 12M+ 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⭐️

Whether it's a two-week MVP or a long-term Mobile App Development build, I care about shipping the right thing - not just more things. ⚡️ I respond in under 10 minutes during working hours.

If you need Flutter App Development, React Native, full stack developer support, or AI Development from someone who has shipped real products at scale - send me the details and I'll tell you honestly what it'll take.

🤝 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 disappear after the App Store approval - I stick around for the messy part: real users, real reviews, real iteration. Most of my work is repeat clients and referrals, because shipping once is easy and shipping something that keeps working is the hard part. If you've been burned by a flutter developer or mobile app developer who delivered a demo and vanished, that's exactly the gap I fill.

🌍 I work with founders, startups, and product teams worldwide - from a first MVP to scaling an app past 1M users. Clear communication, fast replies, honest scope estimates, and no surprises on the invoice. Whether you're validating an idea or rescuing a stalled build, I'll bring the same product-first thinking that took UpLife, Parlor, and GoFrendly to scale.
