I’m Arin, a computer science graduate who has worked in enterprise security operations and cloud security engineering. I’m most interested in detection, incident response, vulnerability management, and the tooling behind all three.
See what I’ve been building →I use this space to show what is changing between releases: new detection logic, harder test cases, clearer technical notes, and the security concepts I am actively reinforcing.
SignalF0rge now combines 24 native detections and cross-source correlation with entity-centric cases, read-only investigation tools, bounded entity-graph pivots, an optional LLM planner, evidence-cited AI narratives, and a standalone HTML investigation dashboard.
Read the technical breakdown →Evaluation now mixes 3,000 ordinary benign events with legitimate attack-like administration and 21 labeled attack scenarios. The adversarial baseline preserves 100% attack-case recall while exposing 8 known false-positive cases for future tuning.
Reinforcing network security, identity and access management, incident response, cryptography, and security architecture through focused study and labs.
30 external pull requests submitted, spanning secret handling, authentication, AI-agent security, vulnerability scanning, CI, and developer tooling.
See contributions and writeups → View all my GitHub pull requests →Shipped merged contributions across secret handling, API authentication, CI maintenance, security-audit tracking, and developer tooling, with additional vulnerability-scanning and AI-agent security work under review.
Expanded SignalF0rge into an evidence-grounded investigation workflow, added agent safety controls and SOC-style reporting, then measured it against 3,067 mixed events: 79.49% precision, 100% recall, and 88.57% F1.
Strengthened defensive parsing and verification with fuzzing, automated tests, and CI coverage.
Published project breakdowns covering detection correlation, reverse-proxy engineering, and AWS hardening.
Worked through IAM, S3 policy, security-group, and least-privilege hardening decisions.
Security operations at J&J MedTech and security engineering at CloudDefense.AI.
SignalF0rge, CinderProxy, and an AWS hardening lab.
