About

Looking for an AI chatbot developer based in Europe? I am Kirill Strelnikov, a freelance developer in Barcelona specializing in custom AI chatbot development. I build intelligent chatbots that handle customer support, drive sales, and automate business workflows using OpenAI, LangChain, and Django. All solutions are GDPR-compliant with European hosting. I work with clients across Spain, Germany, France, the UK, and beyond.

What I Build

  • Customer support chatbots (70% ticket reduction)
  • AI sales assistants with product recommendations
  • WhatsApp and Telegram bots for business
  • RAG-based knowledge retrieval systems
  • Multi-channel chatbot platforms
  • CRM-integrated lead qualification bots
  • Internal automation tools with AI

My tech stack: Python, Django, Django REST Framework, PostgreSQL, Redis, Celery, Docker, OpenAI API, LangChain, Telegram Bot API, Stripe, FastAPI, Nginx, Git, Linux.

How I Work

1. Use-case workshop — We map your customer journey, identify the top repetitive inquiries, and define what the chatbot should handle vs. escalate to humans.

2. Prototype in 1 week — I build a working chatbot prototype connected to your real data so you can test actual conversations before committing.

3. Training & refinement — I fine-tune prompts, add guardrails, and integrate with your CRM or helpdesk. You review accuracy metrics at each stage.

4. Go-live & monitoring — Deployment on your domain with analytics dashboard. I monitor for edge cases and retrain as needed during the first month.
