Hi, I'm Sanjay Singh.
I'm the founder and sole developer behind Smart Solution — a one-person freelance practice, not an agency with a sales layer between you and the person actually writing your code.
Shopify, in depth
I've built or worked on 200+ Shopify stores — new store launches, redesigns, theme customization, checkout/payment setup, and performance fixes across niches like fashion, home goods, electronics, and general D2C. Beyond stores, I've built and published Shopify apps myself, so I understand the platform from both the merchant side and the developer/API side.
Real, checkable project work
Rather than a stock-photo portfolio, see specific projects — what was built, for whom (where the client is comfortable being named), and links to live results — on the Portfolio & Case Studies page.
Beyond Shopify
I build custom websites and web apps outside the Shopify ecosystem too — on modern, maintainable stacks, with proper hosting and deployment rather than throwaway code. I've worked across multiple CMS platforms depending on what a client already has, rather than forcing everyone into one tool.
AI chatbots & RAG assistants
My AI work spans retrieval-augmented generation (RAG) assistants, LLM/SLM-based chatbots, and lead-qualification agents. I focus on assistants that are grounded in a business's real content, not ones that confidently make things up.
What you get by hiring one developer instead of an agency
Direct communication
You talk to the person building your project — no account manager relaying messages, no junior dev you've never met.
Fixed, published pricing
Scope and price are agreed before work starts. See the Pricing page for exact numbers.
Real, checkable work
200+ stores shipped, with specific case studies on the Portfolio page — not a portfolio of stock screenshots.
