2020 – Present

Teaching Technology with Clarity, Practical Experience, and Real-World Impact

Teaching technology and cybersecurity Erika Hernandez began her teaching journey in 2020 working with K–6 students, introducing foundational computer concepts through Code.org and beginner-friendly Python activities. What started as an opportunity to teach technology quickly became a passion for helping others build confidence in technical skills through clear communication and hands-on learning.

Since then, Erika has expanded that passion into higher education, developing and teaching courses focused on computer fundamentals, cybersecurity, networking, and industry certification preparation. Her instructional experience includes teaching:



• Basic Computer Skills (BCS)
• CompTIA A+
• CompTIA Network+
• CompTIA Security+
• Cybersecurity Foundations
• Linux & Infrastructure Concepts
• Protocol Analysis & Wireshark Fundamentals

Erika’s teaching philosophy centers on making technology approachable, practical, and relevant to real-world careers. She is known for breaking down complex technical concepts into clear, understandable explanations that connect with students from diverse backgrounds and experience levels. Her classroom approach combines:

• Hands-on technical labs
• Real-world IT and cybersecurity scenarios
• Interactive learning and discussion
• Certification-focused preparation
• Practical troubleshooting and problem-solving

Beyond technical instruction, Erika focuses on helping students build confidence, communication skills, and professional readiness for the IT and cybersecurity industry. Her ability to connect with both technical and non-technical audiences has become one of her strongest leadership qualities — whether teaching students, mentoring teams, or collaborating with executive leadership.

Teaching has strengthened Erika’s ability to lead with patience, adaptability, and clarity while helping others navigate complex technology with confidence.

Interactive Cybersecurity Learning Demos

These interactive activities reflect the way I approach teaching technology and cybersecurity concepts: practical, hands-on, and easy to understand. Rather than focusing only on theory, I believe students learn best when they can actively engage with real-world security concepts and see how they apply in modern IT environments.

The activities below introduce foundational cybersecurity topics including password security, phishing awareness, and multi-factor authentication (MFA) through simple interactive demonstrations designed to make learning more approachable and engaging.

Password Strength Checker

This activity demonstrates how password complexity affects account security. It introduces learners to password best practices including length, uppercase letters, numbers, and stronger authentication habits.

Enter a password to test its strength.

Phishing Email Awareness Demo

This activity helps learners identify common phishing indicators such as suspicious sender domains, urgent language, and attempts to collect sensitive information.
