Davide S.

With nearly 20 years of experience in enterprise IT, I bridge the gap between high-level architectural strategy and the hands-on reality of daily operations. My background isn't just in spinning up servers; it's deeply rooted in mission-critical middleware, financial systems, and global-scale infrastructure for companies like ADP, Adevinta, Luxottica, and Nestlé. If you are looking for a consultant who can drive a project from the initial whiteboard design to the final production deployment (and ensure it stays up at 3 AM), I can help. My Core Value Proposition: I offer end-to-end ownership of your infrastructure. I specialize in taking complex, legacy, or chaotic environments and transforming them into streamlined, automated, and cost-efficient cloud platforms. HOW CAN I HELP YOU ---------------------------- - End-to-End Cloud Modernization: I lead the full lifecycle—assessing legacy monoliths (on-prem/middleware), designing the cloud-native architecture (AWS/Azure), and writing the Terraform code to make it real. - Operational Excellence (SRE): Architecture is useless if it breaks. I implement SRE best practices, observability (Datadog/Grafana), and auto-scaling logic to ensure 99.99% availability for critical workloads. - FinOps & Cost Reduction: leveraging my Master’s in Financial Management, I don't just "cut costs"—I re-architect for financial efficiency. I have a track record of implementing tagging strategies and rightsizing automation that significantly reduce OPEX without sacrificing velocity. - Security First (DevSecOps): I build Zero Trust models and integrate security directly into CI/CD pipelines (SAST/DAST), ensuring compliance with strict regulations like SOX and GDPR. SERVICES ------------- Cloud Architecture & Migration: "Lift and shift" or complete refactoring of legacy applications to AWS, Azure, or GCP. Infrastructure as Code (IaC) Development: Writing modular, reusable Terraform libraries for immutable infrastructure. DevOps & CI/CD Pipelines: Building advanced pipelines (GitHub Actions, TeamCity) to automate testing, security scanning, and deployment. Kubernetes & Container Orchestration: Designing and managing production-grade clusters (EKS, AKS, OpenShift). FinOps Consulting: Cloud cost auditing, budget forecasting, and resource optimization strategy. Middleware & Backend Operations: Deep expertise in IBM WebSphere, MQ, and enterprise message buses. TECHNICAL STACK AND SKILLS ---------------------------------------- Cloud Platforms: - AWS: EC2, Lambda, S3, RDS, VPC, Elastic Beanstalk, Workspaces. - Microsoft Azure: App Service, AKS, Virtual Machines. - Google Cloud Platform (GCP): Integration with TensorFlow/AI workloads. - Private Cloud: OpenStack, IBM Cloud. DevOps & IaC: - Infrastructure as Code: Terraform (HashiCorp Certified), CloudFormation. - Containerization: Kubernetes (CKA Certified), Docker, OpenShift, Rancher, Helm. - CI/CD: GitHub Actions, TeamCity, Jenkins, Rundeck. - Config Management: Ansible, HashiCorp Consul & Vault. Operations & Observability (SRE): - Monitoring: Datadog, Grafana. - OS: Linux (Red Hat Enterprise/CentOS), Solaris SPARC, Windows Server. - Middleware: IBM WebSphere (WAS, MQ), JBoss EAP, Apache Solr. Languages & Scripting: - Python, Bash/Shell, HCL (Terraform). Compliance & Security: - Zero Trust Architecture, SOX/GDPR Compliance, SAST/DAST integration. PORTFOLIO HIGHLIGHTS -------------------------------- Global HCM Platform Governance (ADP) - Challenge: Managing governance and compliance for a massive hybrid cloud environment serving millions of users. - Action: Architected a Zero Trust security model and standardized deployment patterns across AWS and Azure. - Result: Reduced compliance audit times by 40% and achieved 100% SOX/GDPR compliance. Finance Transformation & SAP Integration (Adevinta) - Challenge: Securely connecting internal applications to SAP S/4HANA for a global finance transformation. - Action: Designed a secure AWS middleware layer and implemented a Zero Trust network for BPO partners. - Result: Enabled secure, high-availability access to sensitive financial data with improved incident detection via Datadog SLOs. Supply Chain Infrastructure Modernization (viaPhoton) - Challenge: Slow provisioning times for manufacturing edge-locations and security vulnerabilities. - Action: Engineered modular Terraform libraries and implemented GitHub Actions pipelines with automated security scanning. - Result: Reduced provisioning time from days to hours and secured the software supply chain.
