Data Scientist at Siemens Energy who developed a Python microservice connecting external events to Azure Event Hub.

Germany

Message

At Siemens Energy, I developed an end-to-end Python microservice that retrieved events from an external API and published them to Azure Event Hub for a proof of concept integrating a multi-agent system with the EcoMAIN platform.

I also worked part-time as a Data Analyst at Siemens Energy, building SQL and Alteryx data workflows and creating Tableau dashboards and reports. I supported data migrations and maintained a collaborative database for portfolio and development data.

At IT Grow Division Limited, I collaborated on RESTful APIs using Python and PHP, optimized MySQL databases, and created Python and Spark data extraction scripts for analytical data pools and Power BI dashboards.

My projects include SENSATION, an assistive navigation system using semantic segmentation and Valhalla GPS routing, and an ongoing German driving-law chatbot built with React, FastAPI, and LangChain.
