One subscription, three certifications: CompTIA Security+, AWS Cloud Practitioner, and Cisco CCNA. Spaced repetition weights review time by the real exam's domain percentages, not equal time on everything. Full-length, correctly-timed mock exams give an honest score estimate, always labeled an estimate, never a prediction. Every question is written fresh from the public exam blueprint; nothing copied from real exams or braindumps, and requests to check leaked questions are refused outright.
Know if your backtest is a real edge or overfit noise. Runs bar-permutation MCPT, Deflated Sharpe, PBO/CSCV, Hansen SPA, Romano-Wolf StepM, a stationary bootstrap and an out-of-sample split on your own returns — no market feed, no API keys.

Run authorized penetration tests / vulnerability assessments end to end: Rules of Engagement (authorization & scope) → recon/enumeration → OWASP Top 10 review → CVSS triage → concrete remediation → a formal assessment report for executives and engineers. Defense-focused: it centers authorization management, systematic enumeration, risk evaluation, and a client-actionable deliverable — not offensive payloads. Authorized targets only; no DoS, destruction, or evasion.
