Independent engineer & AI founder

Useful AI.
Thoughtfully
built.

I’m Jonas Adler. I build practical AI tools and dependable software for small teams. From a first idea to something people actually use.

Built with intention.Human judgment first.Small teams, real problems.Berlin, and everywhere.

01 / Selected work

A few things
taking shape.

Independent projects and early experiments.
Different ideas. The same focus on usefulness.

02

Fieldnotes

A calmer place to turn research, reading, and unfinished thoughts into something worth keeping.

03

Quiet Ops

Small automations for the repetitive work between the tools. Predictable by default, with a person in control.

02 / A little about me

Based in Berlin.
Curious by nature.

An engineer’s mindset.
A founder’s curiosity.

I’m interested in the space between what technology can do and what actually makes someone’s day better.

My work brings together backend engineering, product design, and applied AI. I like starting with a conversation, finding the smallest useful version of an idea, and building from there.

Outside the editor: long walks through Berlin, independent bookshops, a notebook full of half-formed ideas, and a fairly serious relationship with coffee.

03 / Working notes

A few things
I keep coming back to.

[ 01 ]

Start with the work.

Understand the everyday task before choosing the technology. Sometimes the best AI feature is a better search box. Sometimes it’s no AI at all.

[ 02 ]

Make the edges clear.

Useful tools explain where an answer came from, what they can do, and when a person should take over. Confidence should be earned.

[ 03 ]

Keep it maintainable.

A small system that someone understands is a good place to begin. Good defaults, readable code, and fewer moving parts go a long way.

An ongoing practice

Stay curious.
Build something useful.
