DANYLO KHOMYSHYN
ML ENGINEER

PROFILE
ML Engineering student at Lviv Polytechnic National University (Artificial
Intelligence Systems). I build backend systems and AI pipelines — from RAG and
LLM integrations to REST APIs and vector databases. I focus on writing clean,
production-ready code and want to grow inside a strong engineering team.

▸ Designed and built a production-ready backend using Python, FastAPI, PostgreSQL, Redis,
telegram.org/khomyshyn13 and Weaviate.
▸ Developed an end-to-end RAG pipeline for PDF, DOCX, PPTX, and TXT documents:
parsing, chunking, embeddings, semantic retrieval, and LLM response generation.
SKILLS ▸ Implemented asynchronous document indexing with Redis queues, retries, worker
heartbeats, and configurable per-model quotas.
▸ Integrated local and cloud LLMs through Ollama and OpenAI-compatible APIs.

C E R T I F I CAT E S EDUCATION
Participation on Data
Lviv Academic Gymnasium 2016-2023
Science Bootcamp
Since I studied at a gymnasium with a math focus, I really liked math
Linux basics from and participated in math olympiads, which helped me pass the NMT
Prometheus with the best score.
B2 First (Cambridge
IT-Step Academy 2016-2021
Assessment English)
I studied various areas of IT such as web programming,
computer application development, games, robotics. I have
taught Python, C++, Java, HTML, CSS, JavaScript.
