Professional Experience
Since March 2012, I have worked as a Digital Forensics Examiner, handling a wide range of investigations, including:
- Copyright infringement
- Data breaches
- Hacking incidents (defacement, credential‑stealing malware, bitcoin‑stealing malware, cryptomalware)
- Theft of sensitive data (e.g., banking credentials)
- Tax evasion
- Money laundering
- Web fraud and financial fraud
I have extensive experience with commercial forensic tools such as:
- FTK
- X‑Ways Forensics
- Nuix Workstation
- Magnet AXIOM
- Oxygen Forensics
- Cellebrite UFED Physical Analyzer
I also develop custom forensic tools when commercial solutions are insufficient.
I have deep expertise in:
- Recovering RAID arrays without prior configuration information
- Analyzing DVR file systems (often proprietary or undocumented)
- Processing large‑scale log datasets containing millions of records
- Understanding Microsoft SQL Server storage internals, gained through extensive tax‑evasion casework
Education
I hold a degree in Electrical and Computer Engineering from the Democritus University of Thrace, Greece.
My master’s thesis focused on:
- Statistical properties of popular internet applications
- Stress‑testing network interface cards and saturated network links
- Identifying traffic patterns using Fourier‑based analysis
Software Development & Automation
I develop tools capable of parsing documented and undocumented data structures directly from raw sources, including direct disk access.
I also developed many forensic tools related to the file systems NTFS and BTRFS in golang.
I use Python to automate repetitive tasks and to support electronic‑fraud investigations through:
- Email header analysis
- OSINT data collection
- Visualization of communication patterns
Web, GUI, and Backend Development
I work with:
- Flask for backend web development
- PyQt and GTK+ 3 for desktop GUI applications
I have also developed tools for:
- XML transformation
- PDF report generation using XSL
Backend technologies I have used include:
- MySQL
- Microsoft SQL Server
- Redis
I follow established software engineering practices:
- Writing idiomatic, maintainable code
- Unit testing
- DRY
