Senior Full Stack Mobile & AI Developer | Flutter, React Native, SwiftUI, Kotlin | SaaS, AI Agents, Scalable Systems
Overview / About Me
I help startups and businesses build scalable mobile apps, SaaS platforms, and AI-powered systems designed for real users, real scale, and real revenue.
With 7+ years of experience and 80+ production apps delivered, I specialize in building full product ecosystems from UI UX and system architecture to backend APIs, cloud infrastructure, and AI integrations.
My core expertise lies in combining mobile engineering with modern AI systems including RAG pipelines, AI agents, automation workflows, and LLM based applications using OpenAI, Claude, Llama, Whisper, and LangChain.
I work across Flutter, React Native, SwiftUI, and Kotlin for mobile apps, and Node.js, Python, FastAPI, and Django for backend systems. All solutions are deployed on AWS with scalable DevOps practices using Docker, CI CD, and Kubernetes where needed.
