Rising Talent
Project details
Need an AI search assistant that helps users find the right option faster?
I can help you build an AI agent for marketplaces, booking platforms, real estate products, directories, or service search systems. The assistant can understand natural language requests, support multiple user-input languages, search by location, landmark, neighborhood, filters, preferences, and then guide users toward the most relevant results.
With experience as a python ai developer, I can create RAG-based chatbot logic that connects your internal data, external APIs, and LLM reasoning into one smooth user flow. As a python full stack developer, I can also support database schema, backend logic, REST API integration, deployment, and lead collection.
If your platform needs a scalable backend, I can work with python fastapi to build reliable API services. My full stack python background helps connect AI features with real business workflows, while open ai developer experience allows me to design smart, contextual conversations that improve search accuracy and user engagement.
Send me a direct message, and let’s discuss how an AI search assistant can support your platform.

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

Suceava, Romania - 6:05 am local time
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 pipelines and analytics
⚡My work combines python full stack engineering, python fastapi backends, LLM architecture and business-focused delivery 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, Node.js, React, TypeScript, PostgreSQL, MongoDB, Supabase, AWS, Azure, Vercel, REST APIs, WebSockets, Tailwind CSS, and Material UI.
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.

📌 LLM-Powered Applications
→ Custom AI chatbots with RAG (Retrieval-Augmented Generation)
→ Multi-agent systems using LangChain & LangGraph
→ Context-aware conversational AI that maintains conversation flow
→ Integration with GPT-4, Claude, LLaMA models
📌 Intelligent Automation & Agents
→ ReAct systems (Reasoning + Acting) for complex workflows
→ Document parsing and knowledge extraction (LlamaIndex)
→ AI agents trained on internal documentation and enterprise data
→ Multi-language support with automatic language detection
📌 Smart Recommendations & Analysis
→ AI-powered recommendation engines
→ Image analysis and classification systems
→ Custom ML models for specific business use cases
→ Performance optimization for production environments
📌 Full-Stack Integration

→ Cloud deployment (AWS, Azure, Vercel)
💡 Recent AI Projects & Real Results
Recent work includes an AI skincare recommendation system that analyzes customer inputs and recommends products, a corporate LMS AI assistant for 100+ branches, a real estate rental assistant using landmarks and neighborhoods instead of only addresses, and a full-stack SaaS AI chatbot platform with multi-agent logic and RAG capabilities.
🛠️ Technical Stack
My experience covers both product engineering and AI development. On the engineering side, I build SaaS platforms, dashboards, APIs, admin panels and automation systems as a python full stack developer ( backend python developer ) backend developer and web developer. On the AI side, I work as a Python AI developer and AI Developer, supporting chatbots, RAG systems, llm integration, OpenAI workflows, benchmarking, machine learning and data science tasks for real business use cases.
⚡My approach is simple: clarify the business problem, design cost-conscious architecture, build clean and maintainable code, show progress through regular demos, and transfer knowledge so your team can use and maintain the system confidently.
Additional relevant experience: I have worked around startup products and teams involving laravel, wordpress, sharepoint, moodle lti, flutter, material ui, html front end, payment gateway, back end development, full stack developer react, full stack java, marketing saas, mls, mls idx, real estate photo, ai video, crypto bot, trading python, dask, pandas, data entry, oxwall, qa analyst, ux designer, product manager, it consultant, seo specialist, journalist content workflows, technical resume writing, python full stack, python fastapi, python ai, llm integration, openai, and custom business automation.
🤝If you need a reliable python full stack developer who can own the full product workflow, or a python ai developer who can build practical AI systems with python fastapi, python ai, llm integration, openai, and scalable architecture, send me a message and let’s discuss your project.
