DMG MORI Heitec Digital
Budapest
Senior Software Engineer
- Brought expertise to CELOS X, a large-scale Industry 4.0 SaaS cloud solution on Microsoft Azure IoT, providing digitization of CNC machines. Delivered features requested by a strategic partner company to automate their factory production.
- Provided technical guidance during development of backend microservices that communicate through REST, gRPC and publish-subscribe messaging (NATS). The services utilized stream processing to transform CNC machine data, persisted time-series data into a PostgreSQL database, and transmitted the results to client business systems.
- Integrated CELOS X with a diverse set of industrial network communication protocols (OPC UA, MTConnect, MQTT) to ensure seamless connectitvity with various business client systems, becoming a domain specialist in them.
- Resolved a critical dependency risk affecting whole system architecture before release. Utilized cross-team collaboration and coordination to ensure stability of components, resulting in successful pre-release mitigation.
- Played a company-level role in talent acquisition by conducting over 15 technical interviews. Assisted on-boarding through hands-on mentoring, architecture documentation and comprehensive on-boarding guides.
