PROFESSIONAL SUMMARY

CRM systems, with deep specialisation in 1C-Bitrix, Bitrix24 (on-premise) and WordPress / WooCommerce. Former

performance tuning, security and deployment. Since 2020 I have worked as an independent contractor for clients in
Ukraine and other markets, and I also build Python/Telegram automation tools for my own e-commerce business. I am
known for clear communication with non-technical stakeholders, accurate estimates and reliable long-term support.
