Hi there đź‘‹

I'm a DevOps Engineer at Exponent, where I architect and operate production infrastructure across 6 cloud providers (AWS, Azure, GCP, Digital Ocean, Infomaniak, Exoscale). With 4+ years of production experience, I currently manage 12+ Kubernetes clusters, 30+ microservices, and 12+ production environments, maintaining 99.9% uptime for systems serving 20k+ daily active users.

I specialize in building automation that scales—I've reduced deployment times from 45 to 8 minutes, cut service onboarding time by 80%, and decreased infrastructure operations by 70% through custom tooling. My work includes engineering a Multi-Cloud K8s Provisioner managing 50+ nodes, architecting a Cloud-Native Database Backup Orchestrator protecting 30+ PostgreSQL instances with 99.99% success rate, and creating reusable infrastructure libraries adopted by 10+ engineering teams. I've also optimized cloud spending, achieving 35% cost reduction through automated lifecycle management.

Key Enterprise Deployments: I've architected and deployed production infrastructure for Africa CDC (Azure-based health information exchange and disease reporting platforms), VITAL WorkLife (GCP-based PHI-compliant case tracking), KGI Fintech (AWS fintech/insurance platform), and Dixence (Swiss managed Kubernetes provider on OpenStack).

Beyond infrastructure automation, I design enterprise observability stacks (Prometheus, Grafana, Loki, Mimir), implement zero-trust security patterns, lead on-call rotations, and build CI/CD pipelines that enforce security best practices. Previously, I developed high-performance APIs as a Backend Developer, giving me a deep understanding of both infrastructure and application layers. I believe the best DevOps engineers are force multipliers—enabling teams to ship faster, fail safer, and sleep better.
