02About

Backend & DevOps engineer at the intersection of clean architecture and applied AI.

I build and operate production systems and developer-facing products end-to-end. On the software side: C#, .NET, Node.js, REST APIs, databases and Docker — including multi-tenant and real-time applications. On the infrastructure side: Linux, bare-metal servers, virtualization, networking and container deployments.

I run my own production hosting (OVH bare metal, SolusVM, Coolify, cPanel/WHM) with an isolated backup environment — owning the full stack from provisioning and SSL/TLS to capacity and day-to-day operations.

I treat AI as production infrastructure: MCP servers, LLM APIs (OpenAI, Gemini, Claude), local models (Ollama/Llama) and automation with n8n are part of my everyday workflow. Currently completing a B.Sc. in Computer Science at HIT.

Core belief

AI velocity doesn't excuse architectural sloppiness.

I write clean, organized code — because shortcuts compound into tech debt that no model can undo later.
