HOW I WORK 1. You tell me what's happening. 2. I reply in writing with what I think is causing it and a fixed price — usually the same day. 3. I fix it, document every change and send you a short report. 4. Two weeks of follow-up support included, so the fix holds. You always know the price before I start, and you can check my feedback from similar jobs on this profile. EDUCATION & CERTIFICATIONS Master's degree in Information Security · Systems Engineer.
