What I'm looking for

I'm looking to build LLM applications, RAG systems, and ML services where I can apply rigorous evaluation, testing, reproducible experiments, and Python API development.

I've built a Consular Services RAG Copilot that retrieves from public official sources, provides cited answers, refuses unsupported requests, and escalates complex queries to a human.

I evaluated cross-encoder reranking on 24 local test queries, reaching Hit@1 of 0.833 and MRR of 0.894. My projects also include a QLoRA reasoning experiment that improved validation strict Pass@1 to 55.0% versus 10.5% for answer-only training.

I build Python ML services with FastAPI, MLflow, Evidently, Docker, automated testing, and reproducible evaluation. Alongside my MSc in Computer Science and Technology, I bring consular-services experience communicating in Kazakh, Russian, Chinese, and English.
