Sobhana Susil
Software Engineer + Healthcare, Ecommerce, Publishing, AI, UI/UX, and Fullstack
About me
I build full-stack products across MERN, AI integrations, workflow automation, and cloud delivery. My work is strongest where product thinking meets practical engineering: clear data models, reliable APIs, fast interfaces, and automation that removes repeated manual effort.
Recently I’ve focused on RAG-based document Q&A, N8n commerce automation, Shopify migration, AWS deployments, and production-ready React experiences.

DocMind — AI-Powered Document Q&A

E-Commerce Migration — Legacy Stack to Shopify
Led end-to-end migration of a client's legacy e-commerce platform to Shopify. Reduced annual infrastructure costs from $20,000 to $8,000 — a 60% saving — with zero downtime cutover and full SEO URL preservation via 301 redirects.
Client Website — Brain Genie
