You will get AI Agent & Automation System using FastAPI, OpenAI, RAG, LangChain
Project details
I will develop a production-ready AI Agent or automation system using OpenAI, LangChain, FastAPI, PostgreSQL, and RAG architecture designed for real-world business automation. This service is ideal for companies looking to build AI chatbots, intelligent assistants, document processing systems, workflow automation tools, or knowledge-base AI agents powered by modern LLM technology.
Your solution will include custom AI agent logic, multi-step reasoning workflows, vector databases, embeddings, and Retrieval Augmented Generation (RAG) to enable accurate responses using your own data. The system can integrate with APIs, databases, CRMs, internal tools, SaaS platforms, and external services to automate complex tasks and decision flows.
I build scalable systems with a high-performance Python + FastAPI backend, secure data storage, API endpoints, and admin controls so your AI agent can connect easily to web apps, dashboards, or internal tools.
Perfect for AI chatbots, support automation, document Q&A, lead management, internal knowledge assistants, research agents, and advanced AI workflow automation.
Built to be fast, scalable, secure, and production-ready. 🚀

About Vishwajeet
Web develper and AI solution architect.
Ahmedabad, India - 9:54 pm local time
I specialize in **end-to-end development and browser automation**, from designing APIs and databases to automating complex workflows and data extraction at scale.
### 💡 What I Do Best
* Build **production-ready web apps** using Django, Next.js, React, and Node.js
* Create **robust browser automation & scraping solutions** using **Puppeteer, Selenium, and Scrapy**
* Integrate **AI/LLM solutions** (OpenAI, LangChain, Flowise) into real business workflows
* Develop **high-performance automation pipelines** that reduce manual effort and operational costs
* Deploy and scale applications on **AWS / DigitalOcean with Docker & CI/CD**
### 🚀 Automation & Scraping Expertise
I design **stealthy, reliable automation systems** that handle:
* Login flows & form submissions
* Session handling, cookies, and authentication
* Data scraping from complex, JS-heavy websites
* Scheduled and large-scale data pipelines
I frequently use **Node.js + Puppeteer** when precision browser control is required and **Python-based tools** for data processing and analysis.
### 🧠 AI & Smart Systems
* GPT-powered chatbots and internal tools
* Vector search & knowledge retrieval (FAISS)
* SQL-connected AI agents for real-time business insights
* Workflow automation powered by LLMs
### ✅ Why Clients Choose Me
* Clean, maintainable, and scalable code
* Clear communication & regular updates
* Strong problem-solving mindset
* Proven experience on **Upwork & Fiverr**
