Linux
Linux is an open-source operating system for servers and systems.
What It Is
System Design (Scalable Software Architecture) is a designing systems that are reliable, scalable, and maintainable. On this site, it matters because it transfers across technical, operational, and venture work instead of staying trapped in one narrow context.

AWS/cloud systems
On-demand, API-driven infrastructure is composed from modular services with explicit cost models, enabling scalable architectures through composition, isolation, and elasticity.
Distributed systems
Multiple coordinated nodes operate under partial failure, requiring replication, coordination, and fault tolerance to deliver reliable global behavior.
Infrastructure as Code systems
Declarative configurations define infrastructure state so environments can be reproduced, versioned, and managed consistently.
Linux systems
A hierarchical, permissioned operating system manages processes, memory, and files through a kernel that enforces resource isolation, scheduling, and hardware abstraction.
Microservices Architecture (Docker, ECS, Terraform)
Designed and built a containerized, auto-scaling microservices framework on AWS — first in 2014, then revised in 2018 with EKS, ArgoCD, Helm, and GitHub...
Security systems
Practices and controls protect systems from unauthorized access, misuse, and failure.
TCP/IP networking systems
Layered communication protocols define addressing, routing, and reliable data transmission across interconnected networks.
What I Learned About Centralized TLS With ACME and Traefik
A cleaner control-plane pattern for TLS: one ACME issuer, shared certificate state, and stateless Traefik edge nodes.
