High-Security Systems Engineer & White-Glove IT Specialist.
Managing mission-critical infrastructure at SIDA-cleared facilities and architecting Zero-Trust environments for high-consequence operations.
Systems Engineer | Infrastructure & Security
Absalom Israel
I specialize in the management and optimization of mission-critical technical operations. My background bridges high-stakes corporate security and Identity and Access Management (IAM) with deep-level systems architecture and Linux administration.
From mastering federal compliance at Logan International Airport to engineering zero-trust network resilience for private infrastructure, I focus on systems that remain sovereign, secure, and independent of external network instability.
I recently had a client told by 'experts' that two machines could not sync without a WAN connection. I solved it with a single ethernet cable and a local-only routing configuration. That "old-school" fix is my philosophy in a nutshell: I don't rely on third-party uptime; I rely on the physical and system-level architecture I build.
Core Competencies:
- Infrastructure Ownership: Linux (PikaOS/Arch), Docker, and self-hosted envs.
- Problem Solving: Ability to debug low-level bottlenecks under high-pressure.
- Security & Privacy: Air-gapped solutions and decentralized P2P networking.
