Dec 2020 - Present • 5 yrs 8 mos
Working as an independent software engineer, I build production-ready mobile applications, web platforms, SaaS products, backend systems, and AI-powered solutions for startups and businesses worldwide. My primary expertise is React Native and Expo development for iOS and Android. I handle mobile architecture, responsive interfaces, API integrations, authentication, payments, subscriptions, push notifications, real-time features, performance optimization, testing, Expo EAS builds, and App Store and Google Play deployment. I also develop Next.js and React web applications, Node.js and NestJS APIs, PostgreSQL databases, admin dashboards, multi-tenant platforms, and AWS cloud infrastructure. My AI experience includes OpenAI, Claude, Gemini, RAG systems, chatbots, virtual assistants, and workflow automation. With 7+ years of professional experience, I have delivered 35+ MVPs and contributed to products used by 57.8M+ users. I manage the full development lifecycle—from product planning and architecture to deployment, communication, and long-term support.
