I keep critical systems online, secure and well understood.

Network Operations Engineer and TechOps Risk Champion at Irembo · MS in IT (cybersecurity and networking), Carnegie Mellon University Africa

I work where operations, security and data meet. At Irembo I run alerting and SLOs, monitoring and incident analysis for the platforms behind Rwanda's e-government services, used by millions of citizens. I also turn what systems show into dashboards, audits and reports people can act on, and I'm building ARIA, a self-hosted system that identifies which service caused an outage.

Quick answers
What do you do?

I'm a Network Operations Engineer and TechOps Risk Champion at Irembo, the platform behind Rwanda's e-government services. I monitor and maintain the availability of production platforms, run alerting and SLOs across five of them, and lead incident management, including incidents caused by external partners.

How I work

From the first alert to the last fix.

What I do when production breaks, and the projects where I built each part.

01 · Detect

Notice it first.

Alerting and service-level objectives across five production platforms, so a problem shows up on a dashboard before citizens report it.

See the project
02 · Scope

Know who is affected.

When an external partner fails, responders see which citizen services are hit and how badly, in one view, instead of guessing.

See the project
03 · Diagnose

Find the real cause.

Many dashboards turn red at once. ARIA correlates metrics, logs and traces to rank the service that actually failed.

See the project
04 · Prevent

Make sure it doesn't happen twice.

The fix becomes an alert, a documented procedure or readiness work like Operation Green, so it is the way things are done next time.

About

Hi, I'm Pacifique.

I started in IT in January 2020 as a volunteer at Ruhengeri Referral Hospital, moved into writing production software at BScholarz, and went on to lead Rhythm Box Associations as CEO and lead developer. Today I work in production operations at Irembo, where the platforms behind Rwanda's e-government services depend on monitoring, alerting and fast, clear incident analysis. In 2026 I finished an MS in IT at Carnegie Mellon University Africa, focused on cybersecurity and networking.

My focus is where security, reliability and reporting meet: finding what is wrong, proving it, and leaving behind an alert, a dashboard or a test so it's easier next time.
