I'm an ML/AI Engineer & Fullstack Developer with hands-on experience in building production-grade AI systems, analytics platforms, and Aftersales solutions.
I combine data science, AI, and backend engineering to transform complex business data into scalable applications, automated pipelines and measurable business outcomes.
My key areas:
- 🤖 Development, validation, and fine-tuning of ML models (classical ML, LLMs, GANs, CNNs) for real-world use cases
- 🧠 Design and implementation of RAG systems, AI agents, and MCP-based architectures (LangChain, LangGraph, FastMCP)
- 🛠 High-load backend engineering (FastAPI / DRF) with focus on performance, reliability, and scalability
- 🔌 API design and integration of AI platforms into production environments
- 📈 Delivery of measurable business value: forecasting, optimization, and decision-support systems in Aftersales
