Experience

Enterprise Architecture Manager

Italian Luxury Brand · February 2024 – present

Contributing to the architecture strategy and to the governance of the application portfolio, together with the group's architecture functions; scouting technologies and vendors; acting as the link between business and technical stakeholders, and mentoring teams on architectural principles.

Main work

• Payment provider migration
  Architectural support for moving payments from one provider to another: impact review on order management, reconciliation and anti-fraud reporting. Wrote two Terraform providers in Go, so that the configuration of third-party platforms is versioned as code, and a command-line tool in Rust for a payment platform's management API.
• First Rust service in production
  Rewrote a small production microservice in Rust, replacing the Java version I had written years before: about 5 MB of resident memory, nearly constant, against a 250 MB baseline, in a container built FROM scratch, with no operating system inside. Traffic is low, but the same the Java version handled.
• Demand approval and AI project governance
  Architectural contributor to demand evaluation and tech gate reviews, and architecture governance in the technical reviews and approvals of AI projects.
• Architecture assessments
  Assessment of existing platforms, with alternative architectures proposed.
• Product information enrichment
  Analysis of the process that enriches product information, from a product's conception to its going on sale.
• Request for proposal for DevOps services
  Definition of the technical details and of the architectural part of the request for proposal.
• Load testing
  Load tests with k6 on back-office systems and internal tools, including distributed load generation on Kubernetes, set up and acceptance-tested with the DevOps team. Generating the load is the start: then comes the analysis of the observability data collected and the search for the bottlenecks, sometimes entirely on my own, sometimes leading with others' support, sometimes in support of others.
• Contributions to DevOps
  Integrated deployment pipelines with a secrets manager, and built a proof of concept of dynamic, short-lived database credentials used through an application's connection pool.
