At ifena, my main role was to create a solid ground for the startup to grow through the creation of stable systems, apps, deployment process etc. The startup was successfully acquired by MDV Molliné GmbH.Keywords: React, React Native, node.js, GraphQL, AWS and PostgreSQL, IoT.- Created an app for operators to do automatic smart meter readings, connecting an Android to a radio device that could capture encrypted payloads. The payloads could be sent to our cloud servers when the operator had internet.- Created an app for tenants to see their water and heating consumption every month from radio messages that were captured from the smart meters. They also could send readings and pictures of the meters via the app in response to the Coronavirus-crisis, so operators didn't need to enter their apartments.- Created a system to process encrypted telegrams sent by the operators and by Gateways installed in buildings allowing us to create an automatic billing system connected to ERAS software.- Created an Admin system to allow our employees to import information from ERAS software and then export again to ERAS with externally gathered information.
