PROFILE / ABOUT

Building beyond tutorials.

I like projects where different parts of a system actually have to talk to each other.

My work ranges from AI-powered automation workflows and backend APIs to full-stack applications that connect external services, databases, messaging platforms, and AI models.

I enjoy automating repetitive processes, designing clean backend logic, and understanding the whole path from a user action to an API request, database operation, and final result.

n8n, LLM workflows, AI agents, APIs, webhooks, and integrations.

Backend

REST APIs, databases, application logic, CQRS, and clean architecture.
