CV
Full-Stack / Product Engineer with 5+ years of commercial experience. I specialize in building practical digital systems for business: backend, frontend, API integrations, CRM workflows, automation, Telegram bots, internal dashboards, data scraping, deployment, and production support.
My strength is not just development itself, but the ability to build a system end-to-end and bring it to a real outcome. I work on projects where leads, sales, process automation, stability, and usability for both teams and customers truly matter. I do not think in isolated tasks — I think like an engineer responsible for the final result.
I have experience working in startups and product-focused environments, where I handled the full cycle: architecture, development, integrations, launch, support, and дальнейшее развитие. I can quickly get into existing projects, bring structure to complex logic, and turn disconnected parts into a clear, maintainable system.
Why clients choose me:
— I take responsibility for the result, not just for a “piece of code”
— I am strong in integrations, automation, and backend logic
— I can quickly understand existing projects and bring them to a stable working state
— I build solutions that are genuinely convenient to use and can be developed further
— I focus on quality, stability, and long-term business value
Core areas:
— Full-stack development
— Backend and API integrations
— CRM / webhook / status workflows
— Telegram bots and automation
— Data scraping and processing
— Docker, servers, deployment, production support
