}About
Python backend developer. At VeloxCode I develop and maintain 13 production Django projects; before that, at the Moscow Region Ministry of Transport, I built a DRF API and asynchronous transport data export. I hold a Master's in Cybersecurity from HSE University, so I pay special attention to code security, and in my postgraduate studies I focus on AI and LLMs: building agents with LangGraph and integrating models via the OpenAI and Anthropic APIs. I'm also growing in Web3 — analysing on-chain data on Solana and EVM networks.
