Summary
👤
Senior🎓
Top SchoolKrzysztof Gajewski is a Digital Forensics & Incident Response technical lead with eight years of hands-on experience bridging network operations, SIEM engineering, malware analysis and reverse engineering at EY and prior roles with IBM and SOC teams. He pairs deep protocol and host-forensics knowledge with practical skills in Python, Bash and tooling—authoring several forensic repositories (RegRipper plugins, SRUM and timeliner tools) on GitHub and sharing research on his blog. Certified across CCNA/JNCIA, CEH/CHFI and advanced DFIR courses, he regularly leads complex incident investigations, threat hunting and endpoint collection workflows. Comfortable operating across Windows and Linux environments, he also brings penetration testing insight to harden detection and response playbooks. Not obvious from titles: he began in network operations and leverages that low-level troubleshooting experience to trace incidents from packet to persistence.
