01 / About

Curious about the weak point.
Serious about the fix.

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

Three disciplines.
One operating mindset.

Security is strongest when it is designed into the platform, automated through the delivery path, and visible in day-to-day operations.

01

Cybersecurity

Threat-led testing and practical controls that uncover risk and reduce exposure.

  • Penetration testing
  • Security architecture
  • Identity & least privilege
  • Hardening & vulnerability management
  • Detection & response engineering
02

Systems engineering

Stable, maintainable platforms engineered for clear ownership and dependable operation.

  • Linux & enterprise platforms
  • Configuration management
  • Networked services
  • Reliability & troubleshooting
03

Cloud engineering

Repeatable cloud foundations that make secure delivery faster, clearer, and easier to govern.

  • Cloud architecture
  • Infrastructure as code
  • Containers & orchestration
  • CI/CD & observability

03 / Engineering approach

Infrastructure should earn trust quietly.

Good engineering is measured in fewer surprises, faster recovery, and systems people can understand.

  1. 01

    Secure by default

    Test attack paths, reduce the exposed surface, and build controls that are clear enough to maintain.

  2. 02

    Automate the repeatable

    Turn manual setup into versioned, testable workflows that behave consistently across environments.

  3. 03

    Design for operations

    Build in the signals, documentation, and recovery paths teams need before production gets noisy.

04 / Technical toolkit

Tools follow the outcome.

A practical toolkit for securing, automating, and operating modern infrastructure.

05 / Field notes

Ideas from the workbench.

Short, practical notes on attack paths, reliable systems, and cloud platforms—written for people who have to make the technology hold up.

Systems engineering

Make failure legible

Reliable systems do not avoid every failure; they make failure understandable while there is still time to act.
