I provide Full Stack Developer work that outlives the launch - a Full Stack Developer who carries the Front End Developer and Backend Developer load on the same project, no vendor handoffs.
My Full Stack Developer focus is CRM, ERP, admin systems and B2B platforms - Full Stack Developer builds with RBAC, audit trails and Stripe billing. Clients come to a Full Stack Developer instead of splitting a project between a Front End Developer shop and a Backend Developer contractor, so QA and deployment stay inside one Full Stack Developer workflow. The Full Stack Developer stack is React, Next.js, Vue, PHP, Node.js, MySQL and Redis, on AWS, GCP and Heroku infrastructure sized for peak loads up to 100K users per second. Adjacent Full Stack Developer tracks: Full Stack Web Developer rebuilds, Python Full Stack Developer pairings for data work, Full Stack Developer AI on a codebase already in production, and Full Stack Developer React funnels.
My Front End Developer track is where a product stops looking like an internal tool - dashboards, admin panels, multi-tenant SaaS consoles and marketing funnels, with pages rendering in under 2 seconds. A Front End Developer React build is the default in a Full Stack Developer engagement: React with Next.js, Tailwind and Redux, plus Front End Developer Next.js server rendering when SEO carries the traffic. My Front End Developer also ships Vue 3 with Pinia when a project already runs a PHP backend. Clients searching for a Front End Web Developer or a React Developer want one Front End Developer who owns component architecture, state and API contracts. Front End Developer AI work grows every quarter: streaming responses, chat surfaces and agent panels in an app that already has users.
My Backend Developer work carries the load underneath - REST and GraphQL APIs, queues, background jobs, reporting and integrations. A Node.js Backend Developer service is the usual answer when real-time traffic or webhook throughput matters, and a Backend Developer Nest.js structure keeps a growing API navigable. On the PHP side the same Backend Developer covers Laravel and custom PHP with MySQL, Redis and OpenSearch. Where a client wants a JavaScript backend end to end, backend NodeJS services sit behind the same Next.js frontend, and a Python Developer joins for data work and AI. My Backend Developer also inherits legacy systems: a WordPress Developer migration out of Gutenberg into a custom platform, an API that keeps answering while it gets replaced.
Clients search by role, and the same engineers field all of them - a Full Stack Developer, a Backend Developer or a Software Developer on the server side, a Front End Developer, React Developer or Vue.js Developer on the client side, and PHP Developer, CRM Developer or ERP Developer profiles. When a build needs a Mobile App Developer alongside the web product, my engineers ship the app on the same Full Stack Developer API.
As COO I oversee every Full Stack Developer engagement - the discovery, matching the right Full Stack Developer engineers, the commercial side. My Front End Developer and Backend Developer engineers own the code, and they say I am full stack developer with more than 12 years of experience - my main skill is full stack development.
Clients hire me for Full Stack Developer work when they need:
- a Full Stack Developer who owns frontend, backend, infrastructure and deployment
- a Front End Developer for a dashboard, console or funnel that has to feel fast
- a Backend Developer for APIs, integrations and reporting that stay predictable under load
Recent Full Stack Developer work I shipped:
- Built a Full Stack Developer identity-verification SaaS on a PHP API with Node.js real-time on MySQL and Redis - 4K+ DAU, 1M+ checks through a public Developer API.
- Scaled a multi-currency voting SaaS to 2M+ users across 10 countries with vote locking and Stripe payouts, $2.5M+ revenue.
- Grew a B2B luxury asset marketplace with 15 engineers - React, Next.js, PostgreSQL, OpenSearch, Stripe - to 26K MAU, 75% MoM growth, 25% engagement.
- Delivered a Full Stack Developer medical-center ERP with registration, cashier, doctor and lab modules for 60 staff and 500 patients a day.
Need a Full Stack Developer who covers the Front End Developer and Backend Developer sides and stays long-term - let's talk.

If you're looking for someone who can build a feature, there are thousands of developers on Upwork.
If you're looking for someone who can understand your product, solve technical problems, and help you make the right engineering decisions, that's where I can help.
I'm a Top Rated Plus Full-Stack Product Engineer with 100% Job Success, $100K+ earned, and 65+ completed projects on Upwork. I also work with the University of Hawaiʻi, building and maintaining research portals, dashboards, and data-driven applications.
Most of the projects I work on are already being used by real customers or internal teams. My job is to understand the existing system, improve it, build new features, integrate third-party services, and make sure the application stays reliable as it grows.
Over the years, I've worked on:
• Enterprise SaaS platforms
• AI-powered applications and automation
• Admin dashboards and internal business tools
• Healthcare and patient portals
• CRM and ERP systems
• Marketplaces and multi-user platforms
• Client portals and reporting systems
• API integrations and payment systems
My primary stack includes Next.js, React, Node.js, TypeScript, Supabase, PostgreSQL, MongoDB, Firebase, Tailwind CSS, REST APIs, Vercel, AWS, and OpenAI integrations.
I care about writing code that's easy to maintain, easy to extend, and easy for the next developer to understand. I don't like quick fixes that create bigger problems later.
Whether I'm joining an existing project or helping build something new, I try to understand the business first. Better software usually comes from understanding the people using it—not just the technology behind it.
If your project needs someone who can take ownership, communicate clearly, and build production-ready software, I'd be happy to help.

🏆 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀 | 💯 𝟭𝟬𝟬% 𝗝𝗦𝗦 | ⭐️ 𝟭𝟭,𝟬𝟬𝟬+ 𝗛𝗼𝘂𝗿𝘀 | 📲 𝟰𝟬𝟬+ 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀 | 🚀 𝟭𝟰𝗠+ 𝗗𝗼𝘄𝗻𝗹𝗼𝗮𝗱𝘀 | 👥 𝟵𝟬𝟬𝗞+ 𝗠𝗔𝗨 | 4.8⭐️ Avg Rating | 💰 $𝟱𝗠+ 𝗥𝗮𝗶𝘀𝗲𝗱 𝗯𝘆 𝗖𝗹𝗶𝗲𝗻𝘁 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝘀
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⭐️
⚡️ I respond in under 10 minutes during working hours.
🤝 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.

I lead a team specializing in web development, mobile development, and SaaS development, with deep hands-on experience building scalable, high-performance products for startups and growing businesses. Our team includes dedicated frontend developers in React, backend developers in Node.js, and UI/UX designers - together we take full ownership of the product lifecycle, from idea validation and MVP delivery to stable production releases.
🚀 MVP & Startup Product Development
We help founders move fast without sacrificing quality through agile web development and mobile development workflows. Our focus is on:
Turning ideas into working MVPs
Building investor-ready demos
Launching beta products quickly
Our team delivers:
Rapid MVP development (UI/UX design - Frontend - Backend)
UX flows and prototyping in Figma
Production-ready code with React, Node.js, React Native, and Swift
Secure third-party integrations (Stripe, Firebase, Auth0, Twilio, Google Maps)
Clean, scalable architecture designed for long-term growth and SaaS development
💻 Web Development
Our React frontend development team and backend developers work together on Node.js to build modern web applications that are fast, maintainable, and scalable.
Front-End (Frontend developers React focus):
React.js, Next.js
TypeScript, JavaScript (ES6+)
HTML5, CSS3, Tailwind
Back-End (Backend developers/development with Node.js):
Node.js, NestJS, Express.js
REST & GraphQL APIs
PostgreSQL, MongoDB, MySQL
CMS & Headless Solutions:
Sanity, Contentful, Strapi
Every project combines React frontend development and Node.js backend development to support performance, scalability, and clean code practices - a foundation that's especially critical for SaaS development.
📱 Mobile App Development
Our mobile development specialists create mobile applications optimized for real-world usage:
React Native for fast cross-platform delivery
Swift & SwiftUI for native iOS apps
Firebase, push notifications, analytics
App Store deployment and optimization
Offline mode, multi-language support, battery efficiency
Our backend developers use Node.js to handle server-side logic, ensuring smooth communication between mobile apps and backend systems.
☁️ Cloud, DevOps & System Architecture
Our backend development team designs and maintains reliable, production-ready infrastructure:
AWS: Lambda, EC2, S3, CloudFront, RDS
Docker, Kubernetes, Terraform
CI/CD pipelines (GitHub Actions, GitLab CI)
Monitoring & logging (Sentry, Prometheus, Grafana)
The goal: stable deployments, predictable scaling, and minimal downtime - essential for any serious SaaS development effort.
🎨 UI/UX Design & Development
We work with strong UI/UX design awareness baked into every stage, not just code execution:
Product discovery & user flows
Design systems & UI kits
Accessibility (WCAG)
Responsive, conversion-focused layouts
This helps ensure the product is not only functional, but usable and intuitive - whether it's a web development project, a mobile development project, or a full SaaS development build.
🤝 How We Work
Direct communication with our frontend developers, React, backend developers, Node.js, and UI/UX design team (no middle layers)
Transparent progress and clear estimates
Agile mindset and iterative delivery
Clean, documented, maintainable code
Result: reliable products built by a team that understands both business goals and technical execution across web development, mobile development, and SaaS development.
