About Me
Lead DevOps Engineer with 9+ years architecting and running cloud infrastructure at scale — from telecom and IPTV platforms at Orange, to United Nations workloads, to Nokia cloud R&D, and today the platform behind Numero eSIM, a global eSIM and virtual-number service used by 30M+ people across 200+ destinations. I've consistently delivered 99.9%+ uptime while cutting deployment times and cloud spend. My expertise spans multi-cloud environments (AWS, GCP, Alibaba), Kubernetes, infrastructure as code, GitOps delivery, and observability/SLO practice. I care about automation that removes toil, platforms that developers actually enjoy shipping on, and mentoring the engineers around me.
