About Me

I'm a Principal Systems Engineer and Solutions Architect specializing in distributed infrastructure, edge computing, and stateless virtualization. With a multidisciplinary background bridging Physics and Computer Science, I focus on building resilient, high-availability systems from the hardware tier up to the application layer.

My current architectural focus revolves around hyper-converged infrastructure (HCI), zero-trust networking, and performance optimization for complex hardware-software bridging. I operate under a cryptographically verifiable digital identity framework.

Current Focus: Edge-to-Origin topologies (Oracle Ampere + Tailscale), Proxmox HCI clustering, stateless Win32 containerization (Docker/Wine), and verifiable cryptographic identity ecosystems.


Core Expertise

  • Linux Kernel Internals & Optimization

Stateless Virtualization & Systems

  • Win32 Containerization (Docker + Wine)
  • Low-Latency Streaming Stacks (xorgxrdp/OpenGL)
  • Binary Dependency Mapping (Ghidra)
  • Bare-Metal Provisioning

Automation & Pipeline Engineering

  • Ephemeral CI/CD Agents (Azure DevOps)
  • Distributed Testing Automation (Playwright/TS)
  • Infrastructure as Code (IaC)
  • Complex Data Reconciliation Workflows (C#/Python)

Cryptographic Identity & Security

  • Web Key Directory (WKD) Implementation
  • GPG Cross-Platform Verification (Ariadne/Keyoxide)
  • DNSSEC & SSL Chain of Trust
  • Secure Remote Auditing

Verifiable Identity & Cryptography

My digital footprint and professional artifacts are cryptographically signed to ensure immutability and provenance.

  • GPG Fingerprint: [TU_FINGERPRINT_MAESTRO_AQUI]
  • WKD Endpoint: https://jahirmedina.com/.well-known/openpgpkey/hu/...
  • Verification: You can verify my cross-platform identity via my Keyoxide Profile or by fetching my public key directly from my domain.
