About this gig

I build AI-powered chatbots and intelligent systems using LLMs, RAG, and modern backend technologies.


With 6+ years in software engineering and hands-on experience in AI development, I create solutions that go beyond simple chatbots delivering real automation for support, sales, and business operations.


What I can build for you:


- AI chatbots using LLM (GPT-like models)

- RAG systems with data ingestion and embeddings

- API integrations (WhatsApp, Telegram, external systems)

- Automation workflows powered by AI

- FastAPI backends and scalable architectures

- Custom AI solutions tailored to your business


I have real experience developing production-ready AI systems, including a chatbot used by support teams, sales teams, and end users, with voice interaction and avatar integration.


Why work with me?


- Real-world AI experience (not just API usage)

- Strong backend engineering background

- Focus on performance, scalability and clean architecture

- Clear communication and fast delivery


If you need an AI solution that actually works in production, feel free to contact me before ordering.


Let's build something powerful.
