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.
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.

Projects and case studies.
Every project opens a full case study: the context, what I did, the decisions I made and the result.
Alerting and SLOs for five national platforms
Alert policies, SLOs and error budgets for five production platforms: web, USSD, payments, integration hub and AI API.
Partner outage impact attribution
When an external partner fails, responders now see exactly which citizen services are affected and by how much, in one view.
ICT risk assessment at Irembo
Assessing ICT operations against ISO 27001 and NIST, and turning the gaps into corrective action plans.
ARIA: automated root-cause analysis for incidents
A self-hosted AIOps platform that correlates metrics, logs and traces to identify which service caused an incident and shorten time to resolution, with no telemetry leaving the country.
Zero trust identity and access for Husk Power
Designed and implemented a zero trust identity and access setup for Husk Power's operations in India and Nigeria.
Uptime methodology review
Reviewed how platform uptime was calculated and proposed a method that measures availability the way users experience it.
Product analytics tracking audit
Tested event tracking across six SaaS products in production to find where analytics events were lost and why.
Playwright regression suite
An automated test suite for six products, where known bugs are written as expected failures so the team finds out as soon as one is fixed.
Operation Green: platform readiness
Led a two-phase readiness initiative across three national platforms: web, USSD and payments.
Ortho-Promed CBC website
Website and content management for an orthopedic social enterprise, with secure sign-in and properly authenticated email.
Music distribution platform for East Africa
Business case and architecture for a service that puts independent East African artists on streaming platforms and pays them through mobile money.
Savings group (ikimina) app
A mobile app to help Rwandan savings groups track contributions and payouts transparently.
From the first alert to the last fix.
What I do when production breaks, and the projects where I built each part.
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 projectKnow 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 projectFind the real cause.
Many dashboards turn red at once. ARIA correlates metrics, logs and traces to rank the service that actually failed.
See the projectMake 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.

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.

Milestones · delivered work, details in the projects
ARIA feasibility shown in simulation
Simulations of the diagnosis pipeline show the approach is feasible. Accuracy validation and operator dashboards come next.
Delivered production tracking audit and regression suite
A tracking audit across six products with 17 root-cause issues, a data-loss analysis and a 38-test Playwright regression suite.
Partner outage impact attribution released to production
Responders can now see every citizen service affected by a partner outage in one dashboard.
Zero trust identity and access implementation delivered
Azure Active Directory with MFA, conditional access and role-based access control, documented for audit.
What I work on.
Each area links to a project where you can see it in practice.
