Tech Lead & Offensive Security
I am a **Tech Lead and Backend Developer** operating under the alias **BitSentry**. My focus is security-by-design, building high-scale systems that remain resilient against modern threats.
At Councilbox, I own the **product security posture**, bridging core backend engineering with internal offensive audits and pentesting. My goal is to ensure security isn't a patch, but a native part of the software lifecycle.
"Galicia Skills Gold Medalist and Spain Skills finalist. Independent security researcher and offensive lab enthusiast, focused on delivering technical value from the very first bit."
