I work on cloud support, identity, troubleshooting, and the occasional practical tool.
I am currently a Support Specialist at NIO, focusing on cloud-related issues for NIO Power.
Previously, at Microsoft Entra ID, I specialized in identity and access management (IAM), including
device registration, Windows Hello for Business (WHfB), multi-factor authentication (MFA), and
single sign-on (SSO). In addition to my core expertise, I have a strong foundation in Active
Directory, Servers, Cloud Computing, Network Administration, and Front-end Web Development. This
diverse technical skill set enables me to effectively handle a wide range of challenges in a
fast-paced IT environment.

I do my best work where support, systems thinking, and documentation meet: understanding messy technical issues, getting them stable quickly, and leaving the system clearer than I found it.
I like building a clear model of how a platform behaves in production, from architecture and dependencies to the user-facing impact when something slips out of place.
I handle cloud and identity issues with a bias toward calm communication, fast triage, and clear ownership until the problem is actually resolved.
I enjoy tracing vague symptoms back to root causes, especially when the fix needs both technical care and a realistic understanding of the operating environment.
I turn repeated pain points into reusable documentation, small tools, and better workflows so the next person can move faster with less guesswork.
#include <stdio.h>
#include <unistd.h> // for sleep()
int main(void)
{
printf("🚀 Initiating warp drive...\\n");
sleep(1);
printf("🌌 Welcome Voyager, to the Ruianverse!\\n");
return 0;
}
Identity, cloud troubleshooting, incident handling, and practical support workflows.
Small tools, lightweight frontends, and automation that reduce repeated manual work.
A short version of the path so far, from engineering school to identity support to global technical operations.

Half-built experiments and notes waiting for a free weekend.
I am usually happiest talking about support work, identity, tooling, and the occasional side project. Non-working hours are best.
