DevOps Engineer | Python Developer | AI Infrastructure
●​ 1.5+ years of combined experience in building software and managing its lifecycle.
●​ Deep expertise in Python, LangChain, and LLM integration, combined with DevOps best
practices (Docker, Terraform).
●​ I specialize in automating the "routine" to let developers focus on features. Experienced in
building fault-tolerant infrastructures from scratch, ensuring 24/7 availability for critical services.

I don't just "configure tools" — I build resilient, automated infrastructures that understand the code they
run. I have an understanding of bridging the gap between development and operation with IaC
(Terraform), CI/CD optimization, and AI-powered automation. My exceptional advantage is the
implementation of solutions based on LLM and GPU-accelerated environments to expand modern
technology stacks. My goal is to transform infrastructure from a cost center to a competitive advantage.
