Core Architecture Pillars

Frontier DevSecOps & Compliance

Securing the software supply chain without causing delivery friction. Hardened mission-critical deployments within highly regulated sectors strictly adhering to SOC2, ISO 27001, and GDPR frameworks.

Cloud Economics & Transformation

Treating infrastructure spending as a pure engineering challenge. Delivered structural savings through deep cross-platform architecture pivots, resource utilization optimizations, and lifecycle governance.

AI-Driven Infrastructure & SRE

Pioneering the intersection of SRE and Generative AI. Engineered specialized Large Language Model observability and RAG-based vulnerability systems to reduce MTTR and automate complex log analysis.

Engineering Milestones

Principal Engineer / Engineering Manager • Digital.ai
Feb 2023 – Present
  • FinOps Strategy: Spearheaded a structural platform consolidation framework that delivered a proven 85% reduction in AWS OpEx by auditing multi-region utilization and aligning infrastructure topology with business unit economics.
  • IaC Standardization: Evangelized and led the departmental adoption of Terraform and Ansible, standardizing immutable infrastructure patterns and modular blueprints that eliminated manual configuration drift across environments.
  • Secure Supply Chain Governance: Architected and launched a strategic **Vulnerability Gateway** initiative utilizing **Lacework** cloud security and **Trivy** image scanners, programmatically enforcing compliance guardrails directly within continuous delivery workflows.
  • Infrastructure Remediation: Directed technical mitigation and remediation operations across enterprise cloud infrastructure, establishing proactive vulnerability handling paths and hardening multi-vendor ecosystems.
  • AI-Driven SRE Innovation: Designed custom LLM-powered observability mechanisms and a RAG-powered automated security triage layout to accelerate root-cause analysis and compress MTTR.
  • Compliance Architecture: Led end-to-end data gathering, engineering control definition, and compliance telemetry mapping to successfully ensure infrastructure audit-readiness for SOC2 and ISO 27001.
Senior SRE / Cloud Engineer • Striim
Feb 2021 – Feb 2023
  • Resiliency & DR Architecture: Built cloud-agnostic automated Disaster Recovery (DR) frameworks across AWS, Azure, and GCP, securing an aggressive <30 minute RTO for business-critical streaming SaaS platforms without active-passive overhead.
  • Vendor Decoupling & GitOps: Standardized continuous delivery workflows by replacing GCP-native CloudBuild pipelines with generic Bitbucket Pipelines, cleanly eliminating vendor lock-in for global multi-cloud SaaS environments.
  • Shift-Left Security: Integrated static application security testing (SAST) hooks directly into core deployment pipelines, neutralizing software security risks prior to staging environments.
Senior Associate / Head of IT Tools • Sella (Banca Sella Group)
Nov 2014 – Feb 2021
  • Strategic Technical Leadership: Served as Head of IT Tools, managing a direct technology advising pathway to the local CEO and Global Group CTO to steer corporate toolchain modernization strategy.
  • Regulatory Pipeline Overhaul: Refactored legacy manual software releases into a fully automated, auditable Release pipeline cluster that achieved 100% compliance with strict European GDPR data privacy laws.
  • Deep Compiler Customization: Upgraded enterprise code engines to Jenkins 2.0 and modernized static analysis frameworks by engineering a custom SonarQube AST extension to enforce corporate Java syntax rules.
Programmer Analyst • Cognizant
Oct 2011 – Nov 2014
  • Direct Stakeholder Management: Selected uniquely post-engineering training to act as a primary technical interface for international clients, driving requirements mapping and engineering high-traffic media invoicing applications.
  • Process Digitization: Designed and deployed a custom internal Time Tracker automation software for the Project Management Office (PMO), successfully eliminating obsolete, error-prone manual timesheet processing.
