Engineering profileAnnapolis · East Coast
I’m Derryle, an Annapolis-based engineer working across offensive security, systems, and cloud—testing defenses, hardening infrastructure, and building platforms people can trust.
01 / About
I’m a security and infrastructure engineer based in Annapolis, Maryland. I enjoy the work behind calm, dependable systems: tracing the overlooked path, untangling the complicated one, and leaving an environment clearer and stronger than I found it.
02 / Capabilities
Security is strongest when it is designed into the platform, automated through the delivery path, and visible in day-to-day operations.
Threat-led testing and practical controls that uncover risk and reduce exposure.
Stable, maintainable platforms engineered for clear ownership and dependable operation.
Repeatable cloud foundations that make secure delivery faster, clearer, and easier to govern.
03 / Engineering approach
Good engineering is measured in fewer surprises, faster recovery, and systems people can understand.
Test attack paths, reduce the exposed surface, and build controls that are clear enough to maintain.
Turn manual setup into versioned, testable workflows that behave consistently across environments.
Build in the signals, documentation, and recovery paths teams need before production gets noisy.
04 / Technical toolkit
A practical toolkit for securing, automating, and operating modern infrastructure.
05 / Field notes
Short, practical notes on attack paths, reliable systems, and cloud platforms—written for people who have to make the technology hold up.
A useful finding connects the technical weakness to the decisions an attacker can make next.
Read noteThe best control is visible, fast, and placed close enough to the work that it helps before deployment.
Read noteReliable systems do not avoid every failure; they make failure understandable while there is still time to act.
