Hi, I'm Jeff. Known as Skiddle.
Protocol engineer · Founder of Skiddle Labs · Bangkok
Open to consulting and interesting conversations
I run Skiddle Labs, my own company. Right now my team and I are on a protocol-engineering contract for a client I can't name. My background is delivery pipelines and keeping infrastructure running across the cloud and my homelab. If I have to do something twice, I'd rather write a small tool for it.
I'm a fan of open source and open protocols like ATProto, and I write here about infra, the open web, homelab experiments and life, including flying.
Now
- Protocol engineering on contract for an undisclosed client, with my Skiddle Labs team (since Q3 2026)
- Advising Aerialite, the security & privacy startup I co-founded
- Studying for a master's in AI & machine learning at Chulalongkorn
- Flying as a newly licensed private pilot (PPL, early 2026). How it started
