I love reading, but never have time.
So I either listen to audiobooks while running,

Since I’m cheap and don’t want to pay twice for the same book,
the best way to guarantee I never read it is to buy the hardcover

The pain of microblogging:
I try to write short, sharp posts — provoke a bit, cut the fluff.
Then I get frustrated when people miss the nuance and take it literally.
Maybe I’m just not built for a format that rewards being loud over being precise.

Posting here is my way of fighting imposter syndrome.
I can’t tell if I’m a grown man and a CTO of a successful startup —
or just a kid who still needs the approval of his peers and teachers more than anything else.

I play a fun game with our hiring managers.
I tell them great engineers can pick up Spring fast, even without experience.
They nod in agreement — and then hire only people who’ve already used Spring.

There are two wolves fighting in me:
One says we made our lives harder by starting with microservices.
The other says we’d never have had time to split the monolith once hypergrowth hit.

I love Hamburg — lived there for 5 years and always happy to visit.
But I’ll never understand how Hamburgers manage to be happier than most Germans while surviving a negative number of sunny days for six months straight.

Every 6 months, someone suggests replacing on of our Postgres DBs with Elasticsearch because ‘the DB is heavy with search queries.’
I ask: ‘What can Elasticsearch do here that Postgres can’t?’
Five years later — still no Elasticsearch.

Somehow society quietly agreed that GenAI-generated code is acceptable, but GenAI-generated images and videos are not.
Maybe it’s because code feels utilitarian — a means to an end — while art feels personal, expressive.

‘Why are you so stupid, you piece of metal?’

Discovered The Finals last weekend, Arc Raiders the weekend before.
I thought I was too old, slow, and half-blind for competitive PvP shooters.
Turns out I am — but they’re still a blast.
