What I'm looking for

I'm looking to build a cybersecurity career abroad or remotely, contributing across DFIR, application security, DevSecOps, cloud security, and network engineering while continuing to build practical security tools.

I built Crest, a paid native macOS product, from its first commit through v3.5.2 and paying customers. I created its licensing backend on Cloudflare Workers and D1, using hardware-bound keys and offline-verifiable Ed25519-signed tokens.

For my NextBridge capstone, I built and deployed a full-stack cryptocurrency exchange with spot trading, HD-wallet deposits and withdrawals, P2P escrow, KYC, and an admin panel. I secured it with AWS KMS-backed signing, TOTP and WebAuthn, rotating JWT sessions, signed webhooks, rate limiting, tamper-evident audit logs, and prompt-injection defenses for an AI-agent layer.

At Obsrvr FZC, I supported AWS infrastructure, CI/CD, vulnerability management, secure code review, and network security exercises. I also designed an automated OpenVPN-to-Tailscale migration framework with rollback, PKI/X.509 controls, endpoint hardening, and service-health monitoring.

I build security tools as well as use them, including devsecctl, an open-source cross-platform DevSecOps CLI for host triage and safe bundle redaction. My work spans DFIR, application security, cloud security, network engineering, and secure development.
