01Professional experience

Three applications. One complete lifecycle.

At Crédit Coopératif, I contributed to scoping, development, gates, delivery and RUN follow-up.

2024—2026BPCE Group

Objects to explore · 3Click an object in the scene or in the list.

NVD watch Professional contribution · Crédit Coopératif
Designed an NIST/NVD watch application, matched versions to vulnerabilities, added tests and a Jenkins pipeline. A focused report that made risks visible and helped prioritise checks.
QR cards Professional contribution · Crédit Coopératif
Business scoping, web service development, validation, tests, documentation and release preparation. A flow enabling employees to generate a personalised QR code.
Modernised HRIS Professional contribution · Crédit Coopératif
Legacy analysis, functional migration, Java/Angular implementation, tests, documentation and post-release follow-up. A more maintainable and traceable web foundation for HR teams.

02Global interaction

Follow my change.

Run the mission or inspect each gate. Every step explains work I actually performed — not a generic tool definition.

Scope Professional contribution · Crédit Coopératif
Requirements, business rules, tasks, dependencies and change documentation. An explicit scope before building.
Jenkins Professional contribution · Crédit Coopératif
Built and evolved Jenkins CI/CD pipelines with automated tests. A repeatable and visible process before release.
Gates Professional contribution · Crédit Coopératif
Integrated and followed SonarQube and Checkmarx gates. Defects become visible before promotion.
Artifact Professional contribution · Crédit Coopératif
Managed pipeline artifacts in Artifactory. A traceable version from build to deployment.
Deploy Professional contribution · Crédit Coopératif
Prepared releases, coordinated stages and deployed with XL Deploy. A documented change shared with the relevant teams.
RUN Professional contribution · Crédit Coopératif
Followed feedback, reproduced defects, performed first diagnostics and coordinated users/IT/production. Verify the service and return signals to nominal.

03SIRIUS project · team of 3

From Jenkins to Argo CD.

Over three years, SIRIUS evolved from a JavaFX monolith to Kubernetes microservices. We moved delivery from Jenkins to GitHub Actions and Argo CD with GitOps: Image Updater, Argo Rollouts, Blue-Green and Canary strategies.

3 yearsof evolution

Objects to explore · 4Click an object in the scene or in the list.

GitHub Actions Engineering project · team of 3
Evolved the Jenkins chain to GitHub Actions for ING3 services. CI adapted to a multi-service architecture.
Argo CD Engineering project · team of 3
Moved from Jenkins to Argo CD with GitOps: per-environment configuration versioned with Kustomize, images tracked by Image Updater, automatic sync in dev and manual sync in staging and production. Git becomes the reference: drift is visible and a rollback is just a commit.
Rollouts Engineering project · team of 3
Implemented Blue-Green and Canary strategies with Argo Rollouts. Controlled promotion and easier rollback.
Observe Engineering project · team of 3
Instrumented Prometheus/Loki/Grafana, probes and health checks. Correlatable metrics, logs and service health.

04Individual thesis

Do not guess. Prove.

I designed a reproducible protocol to inject ten Kubernetes incidents, collect evidence, diagnose and restore nominal state.

900trials, failures retained

S2 · BFF Individual work
Collect Kubernetes objects, events, logs and rollout state before concluding. Blue-Green protects the active version until promotion is validated.
Signals Individual work
Correlated Kubernetes, Prometheus metrics, Loki logs, snapshots and runbooks. Verifiable hypotheses and controlled recovery.
AI benchmark Individual work
10 incidents × 15 repetitions × 2 models × 3 architectures. 865 usable answers and 35 failures retained in the analysis.
Decision Individual work
Evaluated quality, evidence, stability, latency, tokens and hallucinations. Stable RAG by default; agent reserved for complex cases.

05Beyond the stack

Anticipate. Explain. Unite.

Reliability is also about communication, method and knowledge transfer.

Teach Individual work
Adapt explanations to each student’s level, blockers and pace. Eight students supported and sustained teaching practice.
Anticipate Individual work
Organise, facilitate and hand over responsibilities after graduation. Chess shapes how I anticipate risk and prepare a recovery plan.
Connect Professional contribution · Crédit Coopératif
Document decisions, make progress understandable and share risks. A dual BUILD/RUN culture and a common language across stakeholders.

06Next mission

Let’s build a service we can ship — and recover.

I am primarily seeking a DevOps / Production or Cloud role. This is the DevOps journey; its résumé contains only relevant evidence.
