I build modern web and mobile applications with AI capabilities that improve user experience, automate workflows, and solve real business challenges. My main work is around React, Next.js, Laravel, Node.js, React Native, Flutter, Android, iOS, OpenAI, Claude, Gemini, Firebase, Supabase, REST APIs, WebRTC, authentication, cloud services, and third-party integrations. I enjoy building SaaS platforms, AI-powered applications, business systems, marketplaces, dashboards, and cross-platform mobile apps. I can help with building products from scratch, integrating AI chatbots and assistants, developing secure APIs, implementing authentication, real-time features, payment gateways, cloud infrastructure, and deploying scalable web and mobile applications. I focus on clean architecture, maintainable code, and practical AI solutions that deliver real business value. For me, great development is about understanding the product first, choosing the right technical approach, and delivering reliable applications that are fast, scalable, and built for long-term success.

He has done it again – Superman of rescuing projects. I knew that I shouldn't have been surprise but he over-delivery beyond my expectation. Andrii came to our rescue and delivery a fantastic Android App. He will definitely be developing the iOS version of the app next.

Andrii is extremely professional. If he says that he can complete a project then you better believe that he can. I will definitely rehire him for future projects which will be in the next few days. There isn't any need for me to post a job because from now on, I'll be going to him first. Andrii, thanks for completing this project.
