Backend engineer.

“I design reliable, observable and secure systems: from service architectures to products integrating AI.”

Areas of expertise

My work spans backend engineering, production AI systems and offensive security.

01 · Foundation

I design modular, observable and resilient architectures that can evolve without losing clarity or control.

02 · Systems

I build reliable, traceable and controllable production components, designed both for the teams operating them and the customers using them.

03 · Offensive security

I find weaknesses before they become incidents, from code to architecture choices, then help prioritize concrete fixes.

I conduct this work under the CyberVanguard name.

A software development career built since 2018 and now focused on backend engineering, preceded by roles in systems, networks and digital support.
