Jean Johnsen

Software, automation and technical systems that have to keep moving outside the screen. The goal is dependable operation with less drag between people, process and equipment.

Selected Work

Projects that remove drag from the handoff

The common pattern is the same whether the output is software or a physical side quest: observe the workflow, identify the friction, and leave behind a more useful layer.

Tooling

jGit

A personal Git client focused on fast state overview and safer daily repo work.

Athlete data

LactateLab

Turns raw lactate data into something coaches and athletes can actually use.

Automation

GF2Discord

Routes form submissions directly into Discord so nothing waits in a dead inbox.

Simulation

SmoothLife

A continuous-life simulation exploring behavior, emergence and algorithmic texture.

Game AI

ZergOnThis

A Brood War bot shaped by timing windows, pressure and real-time tradeoffs.

3D side quest

GPS Outfront Mount

A utility-first 3D print built to stay rigid, ride clean and simply do its job.

Approach

Read the system. Remove drag. Build the useful layer.

Working principles

  • Understand the real handoff before designing the fix.
  • Prefer explicit state over clever hidden behavior.
  • Make the next action obvious for the person using the system.
  • Keep the layer useful even when the environment is messy.

What I try to avoid

Dashboards that decorate uncertainty, interfaces that hide the real state, and automation that looks smooth until reality touches it.

What I optimize for

Useful defaults, clear states, calm operation and tools that still make sense when people are tired or under pressure.

The best technical layer is usually the one that makes the system feel less dramatic, not more.
Career and Studies

Code, process and performance under one roof

The path runs through software, operations, engineering studies and elite sport, but the underlying thread is still systems thinking.

Adidas, Team Danmark and the 800m years

Before software and automation full-time, there were years of national and international middle-distance competition.

BHS-PL Beton Cyclist

Transitioned into cycling after my athletics career where i rode in the danish A category.

Transfer to engineering

  • Preparation matters more than drama.
  • Consistency beats noise over time.
  • Execution under pressure is trainable.
  • Feedback loops only work if you respect them.

Open loop, low friction

If there is a project, role or problem space where software, process and real-world execution overlap, that is usually where the conversation gets interesting.
