Python Data Synchronisation Project

An existing system with various micro-services was extended by a new micro-service that synchronizes certain data with an external system. The synchronization is triggered by certain events. The triggering mechanism uses AWS SNS topics and SQS queues. The data is sent to the external system through a RabbitMQ queue.

  • Language: Python
  • Framework: Tornado
  • Deployment: Docker, Hashicorp Nomad, AWS, Hetzner Cloud

Java/Kotlin/Python Micro Services

A number of microservices were implemented for an IDP (Intelligent Document Processing) platform. The data pipeline was not using the full possibilites of concurrent processing, and several changes to the main micorservice and extensive debugging lead to a significant performance increase.

  • Languages: Java, Kotlin, Python
  • Frameworks: Spring Boot, FastAPI
  • OCR, image pre-processing, converting of data formats
  • debugging, performance improvements

SAP UI5 BTP Applications

A number of applications were implemented, using SAPUI5 on the frontend and Java and OData servives on the backend. The applications were deployed on the SAP BTP cloud (dev, test, anfd prod environments).

  • Languages: JavaScript, Java
  • Frameworks: SAPUI5, Spring Boot
  • Data sources: SAP HANA DB, OData Services (to access SAP ERP data)
  • Deployment on the Business Technology Platform (SAP BTP)
