Jacek Wieteska

🪶📖 I was born in the 80s and studied law and administration at a university in Warsaw. My IT career began during my studies when I took my first job at a telecommunications company, sparking my passion for technology. In my next role, I specialized in VoIP technology, gaining expertise in data, cybersecurity, networking, and virtualization. Meanwhile, my legal background fueled a strong interest in computer forensics—a field that merges technical and legal knowledge. 📃 I hold **CompTIA Security+ SY0-601** and **Data+ DA0-001** certifications (earned in 2024) and have worked in various IT roles within corporate environments. Recently, I’ve focused on advancing my skills in data science and cybersecurity, authoring books in several series, including the *Cybersecurity Mastery Series*, *Data Mastery Series*, *Digital Forensic Case Stories*, and *Interview Mastery Series*. 📃 My books are aligned with the certifications I hold, using industry-relevant terminology to educate and help readers prepare for certification exams. I aim to bridge theory with practical knowledge, ensuring that my content supports both learning and professional development in IT and cybersecurity. 👉 Disclaimer: These books are independent resources designed to help readers understand technology concepts.
