I'm a Full-Stack Developer & SaaS MVP Architect with 5+ years building production apps for international clients. I focus on Next.js/React, MERN Stack, SaaS platforms, AI-powered products (LLM integrations, agentic workflows, RAG pipelines), and Shopify Hydrogen storefronts.
I've shipped AI trading dashboards, fintech integrations, and headless e-commerce builds from idea to launch, not just prototypes. I care about clean architecture, fast delivery, and code that still holds up after the MVP stage.
Need a technical partner who can turn a rough idea into a working product? Let's build it.
