What I do
Six disciplines, one standard: it has to work.
02Audio
Pro audio installations
Sound systems designed, installed and tuned for venues and businesses, so they sound as good on day 300 as on day one.
03Audio
Acoustic consulting
Room measurement, analysis and treatment, so a space sounds the way it should before a single speaker goes in.
04Tech
IT infrastructure
Networks, servers and systems for businesses. Set up properly, documented, and kept running.
05Tech
Software, automation & AI
Custom tools, automated workflows and AI agents that take the repetitive work off people's plates.
06Advice
Business consulting
Making businesses more efficient: bringing AI into their workflows, analysing their data and building dashboards so owners see what's really going on.
I'm self-taught. Everything I know about sound, systems and business I learned by building it, and each one kept leading to the next.
It started with speakers. Together with my partner I co-own Acoustic Density, where we design and build them in-house. From there the work grew into installing and tuning audio systems and helping clients get their rooms right.
Running a company also meant building its IT, then writing the software and automations that keep it lean. Today I do the same for other businesses: the infrastructure, the tools, and the thinking about where AI and data can actually save time.
Off the clock
Same habits, different hobbies.

Camera always nearby, mostly for the builds, the road and the places in between.
20 countries
Motorcycles
Long-distance touring with my wife across 20 countries, plus enduro when the road runs out. In the garage: Suzuki LS650 Savage, and more.
