Selected work

A few things I’ve worked on.

01 / 06

Swiss Energy Forecast

ForecastingConformal PredictionMLOpsReact

Energy demand, solar, and wind forecasts for Switzerland, 48 hours ahead. I built a weekly training and promotion pipeline around LightGBM point forecasts and conformal prediction bands; the deliverable is a static React dashboard with the Python pipeline kept separate.

02 / 06

Swiss BGE RAG

Applied AIInformation RetrievalNLP

A multilingual search and question-answering system for Swiss Federal Supreme Court rulings. I combined exact-term and dense retrieval, reranked candidates, and built citation-constrained answers with refusal when retrieved sources do not support a response.

03 / 06

Automated Assessment of Linguistic Abilities of Language Models

Bachelor’s thesis6.0 / 6.0
NLPLLM EvaluationResearch

Extended the open-source Holmes evaluation framework with a Python/Streamlit application for interactive linguistic probing. Researchers can edit input examples, rerun evaluations, and compare predictions across language models. Alongside the application, I investigated quantization effects through reproducible experiments and statistical analysis.

A little about me

I like the messy middle.

I hold a BSc Artificial Intelligence & Machine Learning from HSLU and am now pursuing an MSc Applied Data Science and AI there, applying data and AI to practical business problems.

At Swisslog, I build data workflows, reporting, and automation for operational teams.

Professional experience

Work so far.

    Working Student QEHSSwisslog · Data, Analytics & Automation

    I build data and automation solutions for operational reporting and workflows.

    • Power BI reporting for Cost of Poor Quality (COPQ), QEHS and HSE.
    • Python workflows for transport distances and emissions estimates supporting Scope 3 reporting.
    • AI-assisted invoice extraction and internal apps/workflows with Power Automate and Power Apps.
  2. 2024 – 20251 yr

    Working StudentSaint-Gobain Weber AG · Procurement / Data

    Cleaned and prepared procurement and logistics data with Python, Pandas, SQL, and Excel to support global warming potential (GWP) calculations.

Education

What I studied.

  1. 2025 – today1 yr

    MSc Applied Data Science and AI — HSLU

    In progress, focused on data integration, data quality, and analytics.

    • Master’s thesis with Swisslog, in progress: researching a modular, semi-automated product carbon footprint (PCF) calculation approach using engineering, ERP, and supply-chain data.
  2. 2021 – 20254 yrs

    BSc Artificial Intelligence & Machine Learning — HSLU

    Foundation in machine learning, NLP, statistics, databases, MLOps, and software engineering. My thesis combined reproducible evaluation of quantized and full-precision language models with a usable probing interface.

    • Thesis: “Automated Assessment of Linguistic Abilities of Language Models”.
