Project history

Cloud System Architekt

Im Rahmen einer groß angelegten Erweiterung von Android und iOS Apps wurden verschiedene Funktionen konzipiert und entwickelt, um die Kundenbindung zu stärken und ein konsistentes digitales Nutzererlebnis zu ermöglichen. Dabei lag der Fokus auf der intelligenten Vernetzung zentraler neuer Funktionalitäten, um relevante Inhalte und Mehrwerte kontextbezogen bereitzustellen. Zusätzlich wurden weitere fachliche und technische Ausbaustufen der Lösung konzipiert.
Aufgrund einer hohen Anzahl an Nutzern bestanden hohe Anforderungen an Skalierbarkeit, Ausfallsicherheit und Verfügbarkeit.

AWS, Java, Kubernetes, Quarkus, Redis, REST, OpenAPI, GitLab

Software Architekt und Lead Entwickler

Konzeption und Umsetzung einer plattformübergreifenden mobilen Anwendung für iOS und Android zur Erfassung, Pflege und Synchronisation von Artikeldaten in Echtzeit. Verantwortung für die Frontend-Entwicklung auf beiden mobilen Plattformen sowie für die Entwicklung und Anbindung eines skalierbaren Backends auf AWS mit Golang. Fokus auf performante Synchronisationsprozesse, hohe Verfügbarkeit, benutzerfreundliche Oberflächen und eine stabile technische Architektur.

Es wurde eine Service Plattform entwickelt, die die üblichen Serviceaufgaben der Erzeuger unterstützt und vereinfacht. Dabei wurde die Plattform in die existierende IT-Landschaft integriert und zum Austausch von Daten mit ihr verknüpft.
Aufgaben:
- Technische Leitung und Steuerung eines Teams von 6 Personen
- Steuerung und Priorisierung der Umsetzung in sämtlichen Bereichen (Software Backend/Frontend, Operations, Infrastruktur, DevOps)
- Architektur der gesamten Plattform, inkl. Erstellung, Abstimmung und Umsetzung von Architecture Decision Records, automatisiertem Testing von Unit- bis End-to-End-Tests und Sicherheitskonzepten
- Hands on Umsetzung im Entwicklungsteam
- Entwicklung von Prozessen und Konzepten zum nachhaltigen Betrieb und automatisierten Testing der Platform
- Stakeholdermanagement inklusive Abstimmung von Anforderungen

Cloud System Architect @ DeutschlandCard

DeutschlandCard
DeutschlandCard is a customer loyalty program through which users can collect points both in local stores and online shops. These points can be redeemed for discounts or rewards.
In the 'Digital Content Platform' project, personalized data from editorially maintained and dynamic sources are made available to the customer through the DeutschlandCard Android and iOS apps. The apps, and therefore the platform, are used by several million users and have correspondingly high scalability and availability requirements.
Tasks:
- Stakeholder management including coordination of requirements
- Architecture of the cloud platform including high scalability and availability requirements
- Technical leadership and prioritization of implementation
- Hands-on implementation of the server side within the development team

Principal Cloud Architect, Tech Lead @ HNGRY

Liebherr Hausgeräte
HNGRY is a shopping list management app available in the app stores.
It had 100s of thousands of active users when Bastian left the project. 
Bastian was responsible for 
  • the technical and organizational bootstrapping,
  • the overall architecture with a strong focus on the linearly scalable and highly available microservice cloud architecture,
  • its implementation in Java and 
  • its operations, i.e. during live user access.
Synchronizing the user’s changes on a shopping list across mobile phones is done by a distributed algorithm that was defined by Bastian.

Role: Tech Lead/Principle Cloud Architect
