Backend developer with over 2 years of commercial freelance experience building web services, automation systems, Telegram applications, AI-powered products, and microservice architectures.
My primary languages are Kotlin, Java, and Python. I specialize in designing reliable backend systems, REST APIs, integrations with third-party services, business process automation, and AI-assisted workflows.
I have experience developing both standalone applications and distributed systems involving message brokers, background processing, cloud infrastructure, and containerized deployments.
Recent projects include AI agents, Telegram platforms, marketplace automation systems, subscription management services, recommendation systems, financial simulators, and custom integrations with external APIs.
I focus on writing maintainable code, designing scalable architectures, and delivering solutions that solve real business problems rather than simply implementing technical requirements.
