Need a Flutter app that scales to millions of users? I build cross-platform mobile products: iOS, Android, FinTech wallets, AI-powered tools that ship fast and grow revenue. FxPro: 15M+ users, multiple international awards.
What sets me apart is the rare combination of Flutter depth and full-stack reach. I've architected apps from a 3-month FinTech MVP (Grineo, launched 50% faster than average) to a 15M-download trading platform (FxPro). I work across Flutter, KMP, Swift, Kotlin, React, and Python — so I can own the entire product, not just one layer.
Here's what I deliver:
📱 Cross-platform mobile apps - Flutter, KMP (Kotlin Multiplatform), Swift, Kotlin
🌐 Scalable web - React, Next.js, Node.js, .NET Core
🤖 AI & Computer Vision - Python, PyTorch, YOLO, real-time video analysis
☁️ Cloud & security - AWS, Docker, PCI-DSS compliance, PassKey encryption
Whether you need an MVP in 90 days or a production system built for 10M+ users, I map out the architecture first so you never rebuild from scratch.
📌 FxPro - architected native mobile apps and high-load backend for a 15M+ download trading platform. Won multiple international awards.
📌 Grineo FinTech Wallet - launched secure MVP in 3 months, 50% faster than industry average, with PassKey encryption.
📌 Volga Surf Camp KMP App - increased service usage 2-4x, reduced admin workload by 3x.
📌 PPE Detection System - real-time AI safety monitoring on construction sites using YOLO and PyTorch.
⭐ 5.0 rating | Top Rated on Upwork | Certified: Flutter Development (Udemy), Full-Stack Web & Mobile (Coursera)
I take on a maximum of 3 active clients at a time to give every project focused attention. Send me a message with a brief description of your project and I'll respond within a few hours with a clear next step!

One of my clients grew revenue 500% after I rebuilt their core algorithm. Another called a $500K research platform I led the "gold standard" in their industry. That's the bar I work to on every project.
I build AI-powered web and mobile apps from idea to production. For startups and scale-ups in healthcare, fintech, SaaS, and eCommerce.
What makes me different from most full stack developers: I own the entire AI layer too. Not just connecting an API and calling it done, but designing RAG pipelines, LLM chatbots, OpenAI-backed features, and AI automation workflows that solve real business problems all inside production-grade React Native, React, and FastAPI apps.
What I build for clients:
→ AI chatbots and assistants (OpenAI, LangChain, RAG, Pinecone)
→ AI-powered mobile apps (React Native, Flutter, iOS, Android)
→ SaaS platforms, MVPs, and full stack web apps
→ RAG systems: chat with documents, internal knowledge bases
→ REST APIs, microservices, and scalable backend architecture
→ Payment integrations (Stripe, Twilio) and cloud deployment (AWS, Docker)
Industries I know deeply: healthcare, fintech, eCommerce, SaaS, edtech, logistics.
