@firasbenahmed
Operational cybersecurity master's student and CompTIA Security+ certified telecommunications engineer.
I am a telecommunications engineer pursuing a Professional Master (M2) in Operational Cybersecurity with CompTIA Security+ certification, combining strong networking foundations with growing offensive and defensive security skills.
I have hands-on experience in telecommunications and radio network optimization, having worked as a BSS Support Expert and Radio Network Optimization Engineer where I managed incidents, KPI monitoring, site rehoming and parameter audits across 2G/3G/4G technologies.
I also have software development experience building real-time financial back-office solutions and monitoring interfaces using languages such as Java, C/C++, Python and SQL, and earlier academic research in wireless sensor networks focusing on compressed sensing and clustering.
I seek to apply my cross-disciplinary background in networking, system security and cyber intelligence to an end-of-study internship or early-career role that emphasizes practical security operations, incident response, and continuous learning.
