About
Hey, I’m Manuel.
I work as a Key Account Manager for a tech company that helps brands of any size sell on major online marketplaces.
Gemba Lab is where I turn what I learn on the job into clear notes, workflows, and experiments—mostly to fix ideas in my head and build better systems over time.
If it’s practical, repeatable, and slightly nerdy, it probably belongs here.
What I write about (and what I don’t)
I write about:
- Amazon Vendor
Reporting, decision-making, and day-to-day execution - E-commerce & marketing
How theory actually shows up in dashboards and calls - Homelab & automation
Docker, self-hosting, small systems that remove friction
I don’t write about:
- Generic productivity advice
- Topics I don’t actively use or test
- “Motivation” without execution
This is not a trend blog. It’s a working notebook.
How I think about work
I’m naturally curious, I learn fast, and I like being put in situations where I don’t know everything yet.
My bias is toward:
- Challenging environments
- Learning by building
- Writing things down to really understand them
Most posts start from a real problem I had:
“I need this to work every week without thinking.”
If it survives real usage, it stays. If not, it gets rewritten—or deleted.
Who this is for
Primarily, this site is for me.
Secondarily, it tends to be useful for:
- E-commerce managers
- Marketers working with Amazon data
- Dev / homelab-oriented people who like simple, robust setups
If you like concrete examples instead of abstract advice, you’ll feel at home.

Why “Gemba Lab”
Gemba is the place where work actually happens.
This site is my gemba:
field notes, experiments, and lessons learned while things are running—not in theory.
