• Drove org-wide FinOps optimization across a 3,000-person company: cost-governance policies, compute right-sizing to cheaper SKUs, and storage audits with cold-tier migration, saving ~€500K in the first 3 months.

• Operate a fleet of OpenShift clusters across Azure and on-prem hardware serving 13M users, including cluster configuration and GitOps rollouts via ArgoCD. Workloads include multi-container web stacks, RabbitMQ, Kafka, Graylog, Redis Cluster, and ingestion pipelines behind layered Nginx + Cloudflare ingress.

• Own Azure landing zones aligned with Microsoft CAF — subscription topology, networking, managed SQL backups, and policy/security baselines.

• Build and secure Databricks infrastructure: provisioning patterns, access controls, and network isolation for the data platform.

• Run Cloudflare at company scale — Logpush, edge routing, and ingress fronting OpenShift services (Kaizen handles ~12.5B Cloudflare requests/day org-wide). Debug cross-layer network issues spanning Azure VNets, Cloudflare, and OpenShift SDN.

• Built folder-scoped GitLab CI with dynamic child pipelines, plan→approve→apply gating, and destructive-change guardrails. Lead incident response and root-cause analysis across CDN, observability, and Redis Cluster on OpenShift.

• Designed and built automated deployment infrastructure for maritime vessels, achieving zero-downtime deployments over unreliable at-sea links.

• Automated the deployment of a Laravel application across multiple remote custom Virtual Machines, configured and set up Linux servers, and ran Docker containers with self-healing solutions to address limited connectivity and bandwidth constraints.

• Removed 100% of manual configuration by orchestrating remote vessel provisioning with Ansible, and designed the VPN and proxy infrastructure keeping vessels reachable at sea.

• Configured an Ansible server for automated deployment, secure communication with VPN tunneling, and system monitoring using Grafana, Loki Prometheus, and cAdvisor.

• Managed containerized services (Laravel, MySQL, Redis, Fluentd) with health checks, logging to Papertrail and Grafana, and integrated advanced log management with Loki and auditd.

• Developed and maintained e-commerce web applications using PHP, Laravel, Python and managed databases with MariaDB, ClickhouseDB, Redis.

• Utilized Terraform, Ansible, Jenkins and Docker to craft diverse server setups tailored for distinct environments, including development, staging, and production on AWS infrastructure.

Built Laravel + ML applications, configured Linux/Docker infra, and shipped an MQTT bridge securing comms with 800 remote Arduinos.

Built IVR systems for corporate clients; rewrote the local testing harness (mock data, bash pipelines, service mirroring) for ~3× faster test cycles.
