Hi, I'm Kilvalrikan
A jack-of-all-trades who's never afraid to get his hands dirty — from IT and programming, to building factories, and today crafting loudspeakers in depth.
Head of NEXUS Department · Pyramid Lifestyle Technology (PLT)
The journey so far
I started out in IT as a network engineer and system engineer, running networks and servers for years — from factory network rollouts to VPS/SSL, Linux servers (Debian/CentOS), Socks5, and IPAM on Docker. Along the way I opened my own first computer shop.
I'm also a programmer (web, and some iOS/Xamarin), and one project I'm proud of was building a factory server room from the ground up — construction, HVAC, electrical, generator and UPS, managing the whole thing myself (the full story is in the "Stories" section).
From there I went fully into manufacturing, mastering digital direct-to-fabric textile printing with pigment ink — one of the earliest setups of its kind in Thailand at the time.
Now — loudspeakers & sound
Today I'm fully focused on loudspeakers and sound at Pyramid Lifestyle Technology (PLT), brand WEAVA, a maker of high-quality drivers, car amplifiers, and crossovers. I:
- built pltspeaker.com entirely
- have personally listened to and tested every driver and product in the company
- wrote the audio knowledge site books.pltspeaker.com
- am building and leading the NEXUS department — an advanced R&D lab weaving AI into every process of the organization
