Backend Developer | AI Integration

I am a backend developer with over 2 years of experience in developing server-side services. I have worked with real users and production-level loads, ensuring reliability and scalability of the systems I build. My expertise lies in automating processes, which has allowed me to reduce manual operations by 90%. I have successfully integrated OpenAI API to handle user requests, enhancing the efficiency and responsiveness of services.

I developed and launched a cloud VPN service managed through a Telegram bot, which currently supports over 300 active users and more than 1000 created VPN keys. The system handles 3,000 to 5,000 API requests daily, including bot operations, authorization, and access management. I designed the backend architecture using Node.js with REST API, implemented middleware for authorization and data validation, and structured PostgreSQL databases for scalability.

My work also includes integrating various APIs such as WireGuard and Telegram Bot API, as well as payment systems. I am experienced in setting up Docker, Linux, Nginx, and deploying services to production environments. I implemented logging and basic monitoring systems to ensure service stability and security, including secure storage of sensitive data and protected interactions with external APIs.

In the AI and automation domain, I integrated ChatGPT API to automate user request processing. I developed prompt logic to handle different user scenarios, which significantly reduced the load on manual support by automating responses through large language models. I optimized context formation and reduced request processing time to improve user experience.

I am seeking a position where I can further develop my skills in backend development and AI integration. I am open to remote work and ready for relocation or business trips. I am fluent in Russian and have working knowledge of English. I am motivated to contribute to innovative projects and continue growing professionally in the field of backend and AI technologies.
