Profile

Linux & Virtualization Engineer with automation-first execution.

I design and operate enterprise Linux platforms, standardize delivery through Ansible and Git, and bridge infrastructure operations with practical Generative AI implementations.

TL;DR for Recruiters

My core profile is Linux platform engineering and virtualization, with a strong automation focus. Alongside that, I work on applied AI use cases in Azure and build local-AI projects around llama.cpp, benchmarking, and edge inference. I am comfortable moving between operations, implementation, and technical communication.

Operating Principles

Codify repeatable operations

Every recurring action should move from ad-hoc command execution into tested automation.

State the problem before the tool

Technology choices are justified by incident patterns, constraints, and measurable operational outcomes.

Keep portfolio content safe

Write with practical depth while avoiding confidential architecture, identities, or customer-sensitive data.
