'Industrial Design Engineer' gone tech. UX enthusiast. Coffee addict. Loud music aficionado. Dad. Runner. AFOL. Opinions own.
After 15 years of no certification, I recently went from zero to ‘quite a lot’.
How do I now think about certification, and how do I look back at the journey? Well… with nuance.
(Bonus: Contains a nod to Ingress. The game, not the networking thing)

Driving my son (6yr) to swimming: Lorna Shore was where I left off yesterday. Blastbeats. Crazy speeds. Extreme vocals.
Son hums along the symphonic backdrop, and wants it on his Spotify playlist. 😄
There's hope for humanity. #proud

🧩 Puzzle: Our workloads have labels, ownership is clear and all is fine at the vulnerability management front.
But now come sidecars added by admission controllers. Could be related to service mesh, observability, etc.
This is typically not something in control of the team that owns the workload.
