Project details
Want to launch an AI chatbot SaaS or add smart automation to your existing platform?
I can help you design and build an AI-powered SaaS solution with chatbot workflows, RAG search, multi-agent logic, backend architecture, and a clean user-facing experience. This service is useful if you need an assistant that can answer user questions, process internal knowledge, guide customers, automate support, or connect with external APIs.
With experience as a python ai developer, I can build contextual AI flows using LangChain, LangGraph, LlamaIndex, and GPT-based models. As a python full stack developer, I can support both the AI layer and the product logic behind it, including database structure, APIs, deployment, and integration with your existing tools.
For scalable backend services, I can work with python fastapi and connect the AI system to a modern SaaS frontend. My broader ai developer experience helps turn business requirements into practical AI features, while open ai developer expertise allows me to create reliable chatbot behavior, RAG pipelines, and structured user interactions.
Send me a direct message, and let’s discuss how AI automation can strengthen your SaaS product.

Python Full Stack & AI Developer
Excellent python full stack developer. He is a true professional, highly collaborative and reliable. He did a great job with our Software Development, using python fastapi, flask and MySQL for the backend. As a python ai developer, he perfectly integrated AI features and handled HTML, CSS, and Node.js flawlessly. Highly recommended

I'm Roman, a Python Full stack Developer and Python AI developer with 5+ years in scalable web development and 2+ years in AI/ML. I have built AI systems for skincare, corporate LMS, real estate and SaaS, including a multilingual assistant for a company with 100+ branches and an AI SaaS chatbot platform built over 11 months.
What I can help with:
✓ AI chatbot development with RAG, memory and business logic
✓ OpenAI / Claude / LLaMA integrations for SaaS, CRM, support, and internal tools
✓ AI agents trained on company documentation, knowledge bases, and enterprise data
✓ python fastapi API development for scalable AI backends
✓ React / Next.js dashboards connected to Python AI systems
✓ Database architecture, API integration, cloud deployment, and performance optimization
✓ Custom machine learning workflows, benchmarking, Data Scraping, data pipelines and analytics
⚡My work combines python full stack engineering, python fastapi backends, LLM architecture and business-focused Software Development that reduces manual work and improves user experience. As a python full stack developer, I build full-cycle products from database design and API architecture to React / Next.js interfaces, deployment and long-term optimization. My core stack includes python full stack, Python Fastapi, Flask, Django, Node.js, React, JavaScript, TypeScript, PostgreSQL, SQL, MongoDB, Supabase, AWS, Azure, Vercel, REST APIs, WebSockets, Docker, Tailwind CSS, Material UI, and Git.
As a Python AI Developer, I create AI chatbots, RAG systems, AI agents, document intelligence tools, recommendation engines, and automation workflows. I work with OpenAI, Claude, LLaMA, LangChain, LangGraph, LlamaIndex, vector databases, prompt engineering, ReAct agents, and llm integration for real business use cases.
