I'm a Computer Science student from Ukraine focused on AI automation, backend development, and practical software engineering.

I build systems that connect AI models, APIs, databases, messaging platforms, and external services — with a focus on workflows that solve real problems rather than isolated demos.

Currently looking for Junior / Internship opportunities in:

• AI Automation
• Workflow Automation
• AI/API Integrations
• Backend Development
• Software Development

AI-powered customer support workflow built with n8n, OpenAI, and PostgreSQL.

Receives support tickets through an authenticated webhook, validates and stores them, generates AI-powered tags and priority, creates concise summaries, and updates ticket processing state.

Highlights

• Authenticated webhook intake
• PostgreSQL persistence
• AI-generated tags
• Dynamic priority classification
• Structured LLM output
• Automated ticket summaries
• Error handling and deterministic workflow logic

Stack: n8n · OpenAI · PostgreSQL · REST API · Webhooks · Structured Output

Alongside my projects, I'm building a public Discord knowledge base where I document what I learn while working with automation, APIs, backend systems, and AI.

Instead of publishing only finished projects, I also document the process behind them:

• Workflow architecture and component breakdowns
• API, HTTP, webhook, and backend concepts
• n8n configuration examples and screenshots
• Validation and data-processing patterns
• Mistakes, debugging, and troubleshooting
• Practical notes from building each project
• Structured learning guides and quick navigation

The knowledge base grows together with my projects — from simple API and automation workflows to more advanced AI systems, agents, RAG, databases, and production-oriented integrations.

Language: The Discord server and learning notes are primarily in Russian.
