Odesa, Ukraine - 5:32 am local time
Specialized in Full Stack Development and Mobile App Development with a strong focus on React Native, Flutter, Python, and SaaS Development architecture. As an experienced Full Stack Developer and Mobile App Developer focused on cross-platform iOS and Android apps and SaaS platforms, I work across the entire stack - from React Native and Flutter mobile apps to Python, Node.js, and Laravel backends. With a strong background in SaaS Development, backend API design, and mobile-connected platforms, I bring a backend-first mindset and deep attention to scalability and long-term maintainability. Proficient in React Native, Flutter, Python, Node.js, AWS, and Microsoft Azure as a Software Developer and Senior Web Developer.
Core Specializations
Full Stack Mobile App Development
As a Full Stack Mobile App Developer and React Native Developer, I deliver cross-platform iOS and Android applications that perform like native products. As a Flutter Developer and Flutter Mobile App Development specialist, I build unified experiences where a shared codebase does not mean compromising quality. As a Mobile App Developer covering mobile app design, mobile app development, and full deployment lifecycle, I treat performance and reliability as non-negotiable from day one - not afterthoughts.
Full Stack Web & React Development
As a React Developer and Full Stack Developer, I build end-to-end web solutions using React, Vue, Next.js, and TypeScript on the frontend. As a Web Developer handling both Web Design and component architecture, I create scalable, maintainable interfaces backed by Python (FastAPI, Django, Flask), Node.js, and Laravel. As a Full Stack Developer with React and Node.js expertise, I own delivery from database schema to deployed product - clean API contracts, proper state management, and optimized data flow across every layer.
SaaS Development & Backend Architecture
As a SaaS Developer, I design and build SaaS Development platforms from MVP to mature multi-tenant products - including subscription logic, role-based access, and SaaS business development-ready architecture. As a Python Full Stack Developer and Backend Developer, I build robust APIs with Node.js and Python for high concurrency workloads. As a Full Stack Developer PHP specialist, I support Laravel and PHP-based ecosystems when projects require it. As a DevOps-minded engineer and React Native Developer, I manage infrastructure as code across AWS and Microsoft Azure environments.
AI Integration & Cloud Infrastructure
As a Full Stack Developer focused on AI Integration, I connect web and mobile frontends to AI-powered backends - implementing smart search, real-time suggestions, and LLM-driven features using OpenAI API and LangChain. As an AWS Architect with expertise in AWS (Lambda, S3, DynamoDB), Microsoft Azure, and Azure DevOps, I ensure data handling is high-speed, cost-effective, and secure across Web, iOS, and Android platforms. As a React Web Development and API Integration specialist, I build the connective layer that makes AI functionality feel responsive and production-ready.
