ABOUT ME
[open contact info](look above in the "contact info" section) I’m a Python AI Engineer focused on LLM features and RAG for

chat assistants. I build backend services and RAG pipelines
(document ingestion, chunking, embeddings, relevant context
[open contact info](look above in the "contact info" section) retrieval) and integrate the OpenAI API. I’ve worked in a small team
arseniy-serikov-0912ba3a1/ on projects and prototypes, delivering key AI and backend modules
from requirements to a working MVP. I also developed Telegram
bots and Telegram sales bots (product catalog, orders, basic
SKILLS automation). I use FastAPI and PostgreSQL; I’m familiar with
Docker and Git and have used them for local environments and
Python version control.
