about

Heyo! My name is Alex Leahu and I’m an application security engineer by trade with an interest in all things A/V production. I volunteer as a sound director at a church and help out in other areas of media production and technology.

Computer Security

My journey into security started off through network engineering, network security, and eventually offensive security. I founded a security consulting firm called Forces Unseen where we helped our clients with application and infrastructure security. Before that I worked at Apple as a security engineer and at Bishop Fox as a security consultant. Day to day I spend much of my time reviewing source code and developing exploits. Naturally, I spend a good amount of time coding, whether it’s security tooling, A/V production automation, or other shenanigans when the mood strikes.

A/V Production

A/V production is something that I’ve been involved with for a long time. I was a co-founder of a film production company. At my church, I led a video broadcast team back when Video Toaster was still around, and I helped design and integrate the Blackmagic system that is used today. I’ve also worked with low voltage wiring, networking, and A/V equipment setup for home and commercial installations. For the past ten years, I’ve been involved with live sound in churches.

A Dash, Sprinkle, and a Pinch

Lonely Castle is a unique take on an A/V production blog, bringing the perspective of a hacker, tinkerer, and coder. I find the intersection of software, networking, and A/V production thrilling and I look forward to sharing my experiences, tricks, and projects with the community. Welcome, and I hope you stick around for a dash of A/V production, sprinkle of code, and a pinch of hacking.
