About this gig
I build backend systems and AI/RAG integrations for mobile apps. Whether you already have a UI or are working with a frontend developer, I handle the engine behind it REST/GraphQL APIs, authentication, database design, and role-based access control.
I also specialize in integrating LLM-powered features like AI chatbots, RAG-based smart search, and recommendation engines directly into your existing app, using Node.js, FastAPI, and tools like LangChain, ChromaDB, and Groq/GPT models.
My background includes building multi-tenant SaaS backends, real-time sync systems, and distributed caching layers so whether you need a simple API or a fully scalable AI-powered backend, I can deliver clean, production-ready code with proper documentation.
Let's build something reliable and smart together
