I build machine-learning systems — and run the infrastructure they live on.
Eight years across analytics, systems administration and applied research — a peer-reviewed publication in anomaly detection, and a habit of deploying and maintaining my own work rather than handing it over.
Projects
Filter by what you're hiring for. Projects marked with both tags are the ones where the modelling and the operating were the same job.
Research & education
M.Sc. Data Science
Thesis on multi-agent small-language-model systems for human–robot turn-taking, built and evaluated on the Furhat social robotics platform. Submitted September 2026, colloquium pending.
Evaluating Anomaly Detection Algorithms
S. Hossain, M. S. Hossain, S. Klütterman and E. Müller, “Evaluating Anomaly Detection Algorithms: A Multi-Metric Analysis Across Variable Class Imbalances,” Proc. Int. Joint Conf. Neural Networks (IJCNN), Sept. 2024.
M.Sc. Mathematics
Thesis on face recognition — a comparative study of deep models. Recognised by ZAB as equivalent to a German master's degree.
Capabilities
Two toolsets, one workflow. I don't hand a model over the wall and hope somebody else can keep it running.

Experience
Data Scientist (Working Student)
Analysed over one million TANSS records in Power BI, Excel and R, improving reporting efficiency by 15%. Designed and deployed 20+ KPI dashboards that cut decision turnaround by around 25%, and delivered the stakeholder reporting behind operational planning.
IT / System Administrator (Working Student)
Administered Windows and Mac servers for a fleet of 100+ devices, handling performance and network troubleshooting. Provided L1/L2 support across software, hardware and network issues, resolving 90% within SLA.
Data Analyst
Data cleaning, transformation and statistical analysis in Python to support decision-making, plus ownership of the Power BI dashboards delivering KPI and trend reporting to management.
Let's talk
Open to Data Science, MLOps and Platform Engineering roles in Germany.
Kurzprofil auf Deutsch
Data Scientist mit mathematischem Hintergrund und einer begutachteten Publikation zur Anomalieerkennung (IJCNN 2024). Acht Jahre Erfahrung in Datenanalyse, Systemadministration und angewandter Forschung — von Power-BI-Reporting über die Betreuung von Windows- und Mac-Servern bis hin zu Multi-Agenten-Systemen mit Sprachmodellen. Ich entwickle Modelle nicht nur, sondern betreibe auch die Infrastruktur, auf der sie laufen. Derzeit offen für Positionen in Data Science, MLOps und Platform Engineering. Sprachen: Bengalisch (Muttersprache), Englisch C2, Deutsch B2.
