About this gig

Hi, I'm Sanjna a full-stack MERN developer with 3+ years of experience building production web apps, Shopify apps, and AI-powered features.


What I can help with:

- Full-stack web apps : React/Next.js front ends wired to Node.js/Express APIs, with MongoDB or PostgreSQL, secure auth (JWT/OAuth), and real-time features via WebSockets.

- Shopify development : custom apps (Remix, Prisma, Polaris), checkout UI extensions, and discount/pricing logic built as Shopify Functions.

- AI integration : adding AI-powered features (chat, content generation, adaptive logic) into new or existing products using the Claude API or other LLM providers.


I care about clean architecture, secure-by-default APIs, and code that's built to last not just demoed. Message me with your requirements before ordering if you're not sure which package fits, and I'll point you in the right direction.
