Hello World.
We are Coders Co. – a company started by computer science PhDs who just want to code. We build computer systems and process data for governments, healthcare, marketing and more.
WHAT WE DO
Applications
PDF2GIS
PDF2GIS is an AI-powered application for processing construction plans and turning them into geo-data.
Urbo3D
Urbo3D Climate Game is a SimCity-like game in which students, residents or civil servants can redesign their own neighbourhood.
Projects
Custom Software
For Zorginstituut Nederland we built a datawarehouse storing and connecting various datasets related to the quality of the elderly-home care. We’ve also built a frontend applications that allows to easily explore this dataset. This was a part of the KIK-V program.
Data Science
For BAM we created and put in production a model that predicts future energy usage of their buildings.
Data Engineering
For InterXion we created data pipelines that copy measurements from a hundred thousands of sensors from datacenters to an analytics environment in the cloud. This data is then used to optimize the energy usage of the datacenters.
