Uniper AG

Im Rahmen meiner Tätigkeit bei Uniper arbeitete ich in cross-funktionalen Projektteams an der Optimierung bestehender Prozesse sowie der Konzeption und Umsetzung neuer Lösungsansätze im energiewirtschaftlichen Kontext der Lieferbeginn- und Lieferende-Prozesse der Marktrolle „Lieferant“. Dabei war ich verantwortlich für den Entwurf und die Modellierung eines Knowledge Graphen, einschließlich der Definition des Schemas, der Entitäten und der Beziehungen innerhalb des Graphen. Dies erforderte ein tiefes Verständnis der energiewirtschaftlichen Daten und Prozesse sowie Fachwissen in Ontologien, Semantik und SPARQL. Ich implementierte den Wissensgraphen mithilfe der Neptune-Graph-DB, setzte die Datenbankinfrastruktur auf, importierte Daten und konfigurierte die Datenbank für optimale Leistung. Durch kontinuierliches Monitoring der zentralen Prozesse und die Ableitung entsprechender Maßnahmen gewährleistete ich eine hohe Prozessstabilität vor dem Hintergrund externer Einflüsse wie Gesetzesvorgaben und Regulatorik. Ich bewertete die Auswirkungen dieser Einflüsse und leitete entsprechende Maßnahmen ab. Zur Effizienz- und Qualitätssteigerung identifizierte ich proaktiv prozessuale Weiterentwicklungsansätze. Ich entwickelte und pflegte SPARQL-Abfragen und Mastertabellen, optimierte deren Leistung und stellte ihre Genauigkeit sicher. Zudem führte ich regelmäßiges Testing der angepassten Prozesse mit selbst erstellten Testfällen durch, einschließlich Test- und Fehlerdokumentation. Meine Arbeit erforderte fundierte Kenntnisse der Marktkommunikationsformate, -nachrichtentypen und -prozesse der deutschen Energiewirtschaft mit Schwerpunkt auf Belieferungsprozesse, insbesondere UTILMD. Darüber hinaus verfügte ich über gute Kenntnisse des Abrechnungssystems SAP IS-U und eine nachgewiesene Affinität für Systemprozesse und IT-Plattformen. Meine strukturierte Arbeitsweise, analytischen und konzeptionellen Fähigkeiten sowie meine Hands-On-Mentalität und mein hohes Maß an Eigeninitiative ermöglichten es mir, erfolgreich in agilen Arbeitsumgebungen zu agieren.
