You will get "I will build an AI chatbot or RAG pipeline using LangChain and OpenA
Project details
I build production-ready AI chatbots and RAG pipelines that actually work at scale — not just demos. With 6+ years of full-stack experience and hands-on expertise in LangChain, OpenAI GPT-4, and vector databases (FAISS/ChromaDB), I've built AI systems handling 50,000+ daily requests with 99.5% uptime. My optimized RAG pipelines deliver ~30% better accuracy than baseline implementations. You get clean, documented code, a fully deployed solution, and a developer who understands both AI and the full-stack engineering needed to make it production-ready. From Django REST APIs to React frontends — I handle everything end-to-end so you don't need to coordinate multiple freelancers.

About Neha
AI-Powered Full-Stack Developer | Python, Django, React, Flutter | Gen
Noida, India - 11:45 pm local time
With 6+ years of professional experience, I specialize in Python, Django, and React/Next.js for full-stack web development, and Flutter for cross-platform mobile apps. What sets me apart is my deep expertise in Generative AI and LLM integration — I've built production-grade RAG pipelines, AI chatbots, and ML-powered APIs that handle 50,000+ daily requests with 99.5% uptime.
🔹 What I Bring to Your Project:
→ AI & GenAI Integration
LangChain, RAG architecture, OpenAI GPT-4/Whisper, FAISS/ChromaDB vector databases, embedding pipelines, and LLM orchestration — I turn AI from buzzword into production-ready features.
→ Backend Engineering (Python & Django)
Scalable RESTful APIs, microservices architecture, PostgreSQL/MySQL optimization, Redis caching, Celery task queues, and robust authentication systems — built for performance and reliability.
→ Full-Stack Web Development
Django REST Framework + React/Next.js/TypeScript frontends with responsive UI, real-time features (WebSockets), and end-to-end deployment on AWS/GCP with Docker & CI/CD.
→ Mobile App Development
Cross-platform apps with Flutter (Android & iOS) — published on Google Play Store & Apple App Store. E-commerce, on-demand services, utility apps with Firebase, push notifications, and maps integration.
🔹 Production Highlights:
✅ Improved LLM response accuracy by ~30% through optimized RAG pipelines
✅ Reduced API response times by 25% via database indexing & Redis caching
✅ Built ML serving pipelines achieving 92% ROC-AUC (churn prediction) and 95%+ recall (fraud detection)
✅ Delivered 10+ secure, scalable REST APIs with comprehensive documentation
✅ Published multiple live apps on Google Play Store & Apple App Store
🔹 Full-Service Team Capability:
I work with a skilled mobile development partner, so I can deliver complete end-to-end solutions — backend, web frontend, AND native/cross-platform mobile apps — all under one roof. You get a unified team without the coordination overhead.
🔹 Tech Stack:
Python | Django | Django REST Framework | React | Next.js | TypeScript | Flutter | PostgreSQL | MySQL | Redis | AWS | GCP | Docker | LangChain | OpenAI API | FAISS | Celery | Nginx | Git
Whether you need an AI-powered SaaS platform, a scalable backend system, or a full-stack web + mobile solution — I deliver production-ready, well-documented code on time.
Let's build something exceptional together.
Steps for completing your project
After purchasing the project, send requirements so Neha can start the project.
Delivery time starts when Neha receives requirements from you.
Neha works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Requirements
I'll design the system architecture — API structure, database schema, AI pipeline flow, and frontend wireframes. You'll receive an architecture document for approval before development begins.
Backend Development
I'll build the Django REST API with authentication, database models, and business logic. For AI projects, this includes LangChain pipeline setup, vector database integration, and OpenAI API configuration.
