FunctionHR is a company that specializes in the development of a self-service HR platform. The
platform is designed to provide a user-friendly interface for HR processes and utilizes
technologies such as R-Shiny, React, HTML, Javascript and ReactJS. Within this framework, a
comprehensive HR dashboard was implemented that presents key HR performance indicators.
As a full-stack developer, I provide support in all areas of platform development. The self-service
tool allows the creation of surveys. The HR dashboard contains key metrics to assess
organizational health and performance, including:
Employee satisfaction: measuring employee satisfaction through surveys and feedback
mechanisms.
Turnover rate: Monitoring the rate of employee turnover within the organization.
Recruitment efficiency: Evaluation of the effectiveness of the recruitment process

Keepoala is the first app that tries to avoid returns in two ways. Customers who avoid returns
are rewarded via a loyalty program. A returns portal is used to ask customers why they have
returned items. These insights are merged with various data connections of the online stores
in one system. On a dashboard, the store can then see why returns occur and can use a wide
range of adjustments to avoid this.
Technically, Keepoala consists of 16 pieces of software, including an iOS and an Android
app, several WebApps in ReactJS that run in AWS ECS and AWS EC2 systems, R-Shiny apps
for data analysis and NodeJS backends for connecting various logistics companies.
B2B customers include happybrush, VRESH, steinehelden.de and others.
