About Me

John Harvey Requioma

John Harvey Requioma

Security Analyst | SOC Analyst | Data Analyst

Hi! I'm John Harvey Requioma. I graduated on June 2026 from La Salle University - Ozamiz. I'm moving into cybersecurity, holding the IBM & ISC2 Cybersecurity Specialist, Microsoft Cybersecurity Analyst, and Google Cybersecurity certificates, and I placed top scorer at a DICT-run CTF. I'm open to remote SOC and security analyst roles worldwide.

With over 4 years of hands-on experience, I manage financial records, sales KPI dashboards, and CRM-based customer accounts across an 10-branch service network. I work daily in QuickBooks, Excel, Google Sheets, Power BI, and Tableau for financial reporting, reconciliation, and performance tracking.

My background is in Computer Science, so I also build the internal tools I need — most recently a payroll and record-keeping system that replaced a manual spreadsheet process. I keep a cybersecurity practice on the side through CTF competitions.
