I spoke on PyGrunn this year (May 8th 2026). See the details of this talk below for future reference.

Title List-Man: Pragmatic System Integration
Timeslot 15:00 - 15:30
Location Camera 4 (84 people)

Summary

Time is always limited, but when you have big plans, it’s time to get smart and pragmatic. At the time, the company was rapidly growing and processes were getting more mature every day. It was a dynamic environment with a heterogenous landscape of different information systems. That mix also puts a demand on the data-quality of all those systems; an error quickly goes unnoticed.

Big companies often deploy some kind of enterprise service bus for these kinds of problems, but that was clearly overkill. So I made a plan how to tackle this problem, and presented the vision within ArchiLab, our companies internal vehicle for innovation.

In this presentation I will present a number of examples of what I built, which address actual use-cases within the company. Examples include publishing data on the intranet, visually comparing lists for inconsistencies and recording data on ever changing lists. With these examples I will address things like bootstrapping your project, having an information architecture, software reusability and just building cool stuff. My tooling of choice were Debian Linux (development on Mac OS X), Python, Flask and Postgresql.
