I build production-ready Flutter and React Native apps for iOS and Android, and I specialize in one thing most developers avoid , cleaning up and scaling AI-generated codebases built with Lovable, Bolt, Cursor, or Claude Code.
If your vibe-coded MVP works but needs a real developer to fix the bugs, restructure the code, and get it live on the App Store and Play Store , this is exactly what I do.
What I regularly build:
Secure authentication & role-based access
Subscriptions, in-app purchases & payments
Real-time features (chat, live updates, WebSockets)
API-driven and data-intensive applications
Clean, scalable architecture for long-term growth
AI-generated MVP cleanup & production scaling
I understand how AI tools generate code, where they cut corners, and how to turn an unstable MVP into a shippable product without rewriting everything from scratch.
What clients can expect:
Clean, maintainable code
Honest timelines & daily/weekly progress updates
Clear communication in plain English
Smooth App Store & Play Store delivery
Tech stack: Flutter, React Native, Firebase, Node.js, Laravel, REST APIs, databases, subscriptions, payments, and real-time systems.

Have an app idea but don't know where to start?
Need to modernize existing software, integrate AI, automate business processes, or build a product that can grow with your business?
You're in the right place.
Building software isn't just about writing code. It's about making the right decisions from the beginning. The wrong technology, poor planning, or rushed development can cost months of time and thousands of dollars later.
That's where I help.
I work with startups, founders, and businesses that need more than someone who can code. They need a trusted technology partner who understands business goals, recommends the right solutions, and builds software that's designed to grow.
Whether you're starting with a rough idea or improving an existing platform, I'll help you move from planning to launch with confidence while avoiding unnecessary complexity and costly mistakes.
You focus on your business. I'll handle the technology.
𝗛𝗼𝘄 𝗜 𝗛𝗲𝗹𝗽
Every project is different, so every solution should be too.
I help businesses:
• Turn ideas into clear product roadmaps
• Validate ideas with MVPs before large investments
• Build SaaS platforms, AI solutions, web applications, and mobile apps
• Modernize legacy systems and improve existing products
• Automate repetitive business processes
• Integrate payment gateways, third-party APIs, and enterprise systems
• Design secure, scalable, and cost-effective cloud solutions
• Continue improving products after launch with long-term support and new features
𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗧𝗵𝗮𝘁 𝗠𝗮𝗸𝗲𝘀 𝗕𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗦𝗲𝗻𝘀𝗲
Technology should help your business, not become another problem to manage.
For example, if you're building an app for both iOS and Android, a cross-platform approach can often reduce development costs and future maintenance while delivering an excellent user experience.
If you're launching a startup, we'll identify the smallest version of your product that delivers real value so you can validate your idea before making a larger investment.
If AI can genuinely improve productivity, reduce manual work, or create a better customer experience, I'll show you where it adds value. If it doesn't, I'll recommend a simpler solution instead.
Every recommendation starts with one simple question:
"What's the smartest investment for your business?"
𝗪𝗵𝘆 𝗖𝗹𝗶𝗲𝗻𝘁𝘀 𝗖𝗵𝗼𝗼𝘀𝗲 𝗠𝗲
Technology is only part of a successful project. Communication, planning, and honest advice matter just as much.
When we work together, you can expect:
• Clear communication without unnecessary technical jargon
• Practical recommendations focused on business outcomes
• Transparent milestones and regular progress updates
• Clean, scalable, and maintainable solutions
• Honest feedback, even when a simpler solution is the better choice
• A long-term partner who stays invested after launch
My goal isn't to build another application.
My goal is to build software that helps your business grow.
𝗣𝗿𝗼𝘃𝗲𝗻 𝗥𝗲𝘀𝘂𝗹𝘁𝘀
I've partnered with startups, growing businesses, and enterprise organizations across Healthcare, FinTech, SaaS, AI, Logistics, E-Commerce, Real Estate, Government, and Enterprise Software.
Highlights include:
• 90+ Successful Projects Delivered
• $200K+ Earned on Upwork
• Products Serving 200,000+ Active Users
• Long-Term Partnerships Across Multiple Industries
𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 & 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀
From MVPs to enterprise platforms, I help clients build reliable, scalable software using modern technologies including React, Angular, Next.js, Flutter, React Native, .NET, Python, Django, Node.js, AWS, Microsoft Azure, Docker, SQL Server, PostgreSQL, Firebase, OpenAI, AI automation, cloud architecture, payment integrations, and enterprise APIs.
I don't recommend technologies because they're popular.
I recommend them because they're the right fit for your product, your budget, and your long-term goals.
𝗟𝗲𝘁'𝘀 𝗕𝘂𝗶𝗹𝗱 𝗦𝗼𝗺𝗲𝘁𝗵𝗶𝗻𝗴 𝗚𝗿𝗲𝗮𝘁
You don't need a detailed specification before reaching out. Some of my most successful projects started with a simple conversation and a rough idea.
Whether you're building your first startup, improving an existing platform, integrating AI, or scaling a growing business, I'd love to hear what you're working on.
Send me a message with your idea, your goals, or the challenge you're trying to solve. Together, we'll identify the best path forward and build a solution that's designed not just to launch, but to grow with your business.

Greetings! I am a Mobile App Developer with more than 11 years of experience building applications for iOS and Android. I specialize in React Native development, Flutter development, and native iOS development using Swift. I work with startups, founders, and companies that need reliable mobile software built for real users and real products.
Over the years I have helped launch and improve many mobile apps, from early MVP products to large production applications used by thousands of users. My focus is building stable, scalable, and maintainable mobile applications that work smoothly on both iOS and Android.
As a React Native developer and Flutter developer, I build cross platform mobile apps that share a strong codebase while still delivering a native user experience. When a project requires deeper platform control, I also develop native iOS apps using Swift, ensuring performance, reliability, and clean architecture.
I often join projects where a company needs an experienced mobile developer to build an app from scratch, improve an existing mobile product, or refactor a growing codebase so it can scale properly.

Redis
I build mobile apps that are stable, scalable, and ready for release.
If you need a React Native developer, Flutter developer, or Swift iOS developer, I can help build or improve your mobile product.
