Fermentr
ORIGINWhere it started. A baking & fermentation companion — recipes, an attempt log, and a living timeline of every batch — built to capture what I was learning instead of losing it.
about
A quick index into Michael.
Michael is a product manager in Berlin who builds working software to test ideas instead of only describing them. His path runs through mechanical engineering, event production, analysis, and consulting, so he tends to look for the system underneath a surface problem.
He is building toward a maker-plus-business life: small tools, intentional systems, and projects that help people live or work together with less noise. This site is one of those prototypes, a quick way to find a useful thread before you talk to the human.
For the shortest path: ask the agent a sharper question, or email Michael directly at hello@mxh.dev.
The longer version starts with AI collapsing the distance between an idea and a working prototype. Once he could build enough software in a weekend to learn from it, product work became less about defending documents and more about making systems real enough to test.
Outside the screen, the same pattern shows up in sourdough and kombucha, cycling and the outdoors, drums, family life, and a recurring pull toward communities that function better because someone built the right little system around them.
The projects are works in progress, not finished-product trophies. They are evidence of how Michael starts with a real itch, builds enough to learn, and keeps the question honest.
Fermentr, Bungalow Community Hub, BeeWatch, and HealthBase all orbit the same instinct: turn scattered signal or coordination mess into a calmer system people can actually use.
Bungalow Community Hub
SHIPPINGA private, invite-only hub for the ~50 people who share a plot of land near Berlin. Feed, events, and bookings in one place instead of scattered group chats.
BeeWatch
LEARNINGA solitary-bee emergence tracker for my garden: photos, tube-state tracking, and weather, turned into a labelled dataset. An excuse to learn computer vision on something real.
HealthBase
PERSONALA command-line health hub that pulls Oura, Apple Health, body composition, and nutrition into one local database and prints a single calm morning briefing — recovery, training load, a suggested workout. One clear read instead of five apps.
Writing is where build notes and half-formed product thoughts get clear enough to argue with. A couple of public notes live on the writing page; the draft list shows where the next threads are headed.
Treat the planned titles as prompts, not a finished index. If one of them catches, the better next step is to read the current notes or ask the agent where that topic connects to the work.

Email is the cleanest continuation path. Send the specific thread you want to pick up, or use LinkedIn and GitHub when those are the better fit.
