Why Work With Me
Working Professional
Not a full-time consultant detached from real operations. Currently employed as a cybersecurity engineer with hands-on daily experience.

Reports include actionable remediation steps you can actually implement, not 200-page dumps of scanner output.
Real-World MSP Experience
Prior background contributing to 30+ MSP engagements means understanding real budget constraints and compliance pressures.
Direct Communication
Work directly with the person doing the testing. No layers of account managers or project coordinators.
