What I'm looking for

I seek backend or full-stack roles where I can build scalable APIs, integrate AI services, optimize databases, and work in cross-functional teams focused on performance and reliable production systems.

I am a backend developer with over three years of experience building scalable web applications and APIs using Node.js, Express.js, and Nest.js. I specialize in REST API development, database optimization across MySQL, PostgreSQL and MongoDB, asynchronous programming, and integrating AI solutions to automate message processing and improve user workflows.

In recent roles I built a high-load Telegram sales automation platform with RabbitMQ-delayed messaging, MTProto and Bot API integrations, session/proxy management, and OpenAI-powered agents, and I developed a movie and actor analytics backend with complex schemas, third-party API integrations, and optimized SQL queries for performance and security.
