I build production LLM applications and cloud services in Python. Currently a Software Engineer at EPAM Systems; previously at SoftServe, working on AI assistants, RAG pipelines, and cloud integrations.
- LLM systems — AI assistants, RAG pipelines, and agent workflows with LangChain, OpenAI, and Anthropic models.
- Cloud engineering — asynchronous Python APIs, microservices, and integrations across AWS and Google Cloud.
- Reliability & delivery — LLM evaluation, prompt and pipeline optimization, usage analytics, and automated testing.
