I'm Ewan Spark, a Cloud & Systems Engineer with nine years of experience across enterprise infrastructure and a growing focus on AWS architecture. This is where I document what I build, how I think, and what I learn.
Practical builds with a focus on design decisions, security, reliability and cost.
A proof-of-concept system for employees to submit and track incidents, with role-based access and asynchronous notifications designed around graceful failure handling.
A static website hosted on private S3 behind CloudFront, with Origin Access Control, HTTPS and managed DNS. Designed for low operational overhead and simple deployments.
My background spans Windows infrastructure, enterprise systems, voice and recording platforms, SQL Server troubleshooting and customer-facing technical problem solving. I'm now applying that experience to cloud architecture and building solutions on AWS.
I care about the trade-offs behind a design: choosing the simplest reliable approach, explaining why it works, and knowing what would need to change at scale.
AWS, serverless design, IAM, networking, compute, storage, high availability and cost-aware architecture.
Windows Server, Active Directory, Microsoft Intune, VMware, SQL Server and systems troubleshooting.
SIP/VoIP, enterprise recording platforms, packet analysis and customer-focused incident resolution.
I'm always up for a conversation about cloud, systems engineering and architecture.
