Shopify stores, websites, and AI assistants — built by one developer who's shipped 200+ of them.
Smart Solution is Sanjay Singh's freelance development practice. No account managers, no outsourced dev — you work directly with the person who writes the code, from Shopify builds to custom AI chatbots and RAG assistants.
Four ways I can help your business
Pick one, or combine them — most clients start with a Shopify store or a custom site, then add an AI assistant once the core site is live.
Shopify Development
New store builds, redesigns, theme customization, and custom app development on Shopify.
Custom Websites & Web Apps
Marketing sites, internal tools, and web apps built with modern, maintainable code.
AI Chatbot & RAG Assistants
Support and sales assistants trained on your own docs/products, embedded in your site or store.
Lead-Capture Agents
Conversational agents that qualify visitors and hand you sales-ready leads, not raw form spam.
Live, verifiable work
Instead of a stock-photo portfolio, here's what's actually shipped and publicly checkable today.
200+ Shopify stores
Built new stores and redesigned/fixed existing ones across niches — fashion, home goods, electronics, and general D2C — handling theme setup, app configuration, checkout/payment setup, and store performance fixes.
