What I'm looking for

I'm looking to protect systems through hands-on cybersecurity and IT security work, including security assessments, Linux environments, Python automation, networking, and maintainable client-facing solutions.

I built and deployed SentineLab, a cloud-connected biometric identity and access management system that secured personnel records for 106 users and four administrators at Universidad de Guadalajara.

I hardened the Python, PyQt6, MySQL, and Railway Cloud application with bcrypt authentication, parameterized SQL queries, offline synchronization, TCP socket communication, and a fault-tolerant multithreaded architecture. I also reduced security-critical reporting time by 94% by identifying and remediating duplicate and inactive biometric records.

I'm a Software Engineering graduate and TryHackMe Jr Penetration Tester who enjoys protecting systems, documenting security configurations, and delivering maintainable client-facing technical solutions.
