Our Projects

We supported the recruitment process to expand the software team and established best practices for meetings and task management, including a Kanban board and the two-person rule. We visualised the software system to manage complexity and drive project progress. We provided training on MQTT dataflow for IoT edge applications in battery storage systems and helped design a modular Golang architecture for configurable edge applications, incorporating ADRs and fitness features. We also researched and supported asynchronous data synchronisation for edge-to-customer and edge-to-data warehouse streams, ensuring reliable observability and fault-tolerant transmission.

We designed and implemented the backend using Python Flask, uWSGI, Nginx, Traefik, PostgreSQL, and Redis, following modular monolith principles with CQRS and Event Sourcing. We processed e-book content to enable a speech-recognition-based search algorithm. With Flutter & Dart we re-implemented the iOS and Android app with a new UI and functionality. We developed OpenAPI-based RESTful APIs for user and content management, as well as for searching books. We set up an IAM with a customized Keycloak instance. We also defined the server infrastructure as code (IaC) using Ansible and Docker for deployment on Hetzner Cloud.
