I'm building Comet Cash's hybrid-cloud platform for high-availability financial workloads, improving Bitcoin transaction efficiency by 23% and strengthening transaction security and operational resilience by 43%.

At Nexi Group and NayaOne, I architected secure AI sandbox environments, multi-agent orchestration with LangChain, LangGraph, and Vertex AI, and cloud-agnostic infrastructure that supported LLM inference across the UK, Saudi Arabia, and the US. I've reduced manual verification checks by 40% through infrastructure automation and improved platform capacity by 47% with reliability guardrails.

I've led platform, SRE, cloud, DevOps, and software engineering work at 1nce, Sticker Mule, Workato, PriceHubble, Perforce, Microsoft, Red Hat, Google, and IBM. My work has improved reliability, accelerated CI/CD, strengthened observability, and supported production systems with demanding availability requirements.

I bring 33 years of hands-on experience in platform engineering, multi-cloud architecture, incident response, release standards, and engineering leadership. I care about secure, resilient systems, clear delivery accountability, and enabling engineers to ship reliable products.
