Data Scientist2019 - 2021Octimine
- Conducted research in biomedical named entity recognition (NER) and developed a system in Python that extracts and normalizes chemical entities and diseases from the legal text.
- Created a monitoring system in Node.js to collect information from staging and production servers. Visualized the results and created monitoring dashboards using Grafana.
- Used Docker to containerize external dependencies and runtimes for various system components to alleviate the dependency overhead and create faster development pipelines.
Research Software Development Engineer2018 - 2019Microsoft
Technologies: Web Development, Matplotlib, NumPy, .NET, Visual Studio Code, Visual Studio, Git, Natural Language Processing (NLP), Word2Vec, Anaconda, Agile Software Development, Software Engineering, Data Science, Seaborn, Scikit-learn, NLTK, Pandas, Natural Language Understanding (NLU), NER, Data Visualization, ASP.NET, C#, Python, Regex, Text Classification, Classification, Text Categorization, SQL, Data Analysis, Data Analytics, Data Pipelines, Analysis, Analytics, Scientific Data Analysis
- Developed an automated benchmarking pipeline in Python based on various NLU evaluation metrics. The pipeline runs periodically in an automated fashion and produces up-to-date evaluation metrics of the system and comparisons with competitor systems.
- Worked on back-end servers with C# and .NET framework. Created new API endpoints and optimized existing ones, resulting in a significant drop in response latency.
- Refactored a large system component with legacy code to an extensible design following best-practice design patterns, thus allowing for easier future extendibility while maintaining backward compatibility.

- Collaborated with a chemist colleague on chemical data analysis tasks, focusing on finding patterns and relations between chemical compound structures and their usage in drugs related to specific diseases.
- Conducted experiments in natural language understanding and created a pipeline that performs intent classification and named-entity recognition to automate the processing of client receipts.
- Used image recognition and computer vision algorithms to enhance the capabilities of a license plate recognition system to identify non-standard, hand-written, and multilingual characters.
Research Assistant2015 - 2015Ulm University
Technologies: Ggplot2, C#, Data Science, Data Visualization, Deep Learning, Neuroinformatics, Neural Networks, Machine Learning, Python, R, Data Analysis, Data Analytics, Analysis, Analytics, Scientific Data Analysis, Clustering, RStudio, RStudio Shiny, Dplyr, Tidyverse
- Conducted research in neuroinformatics, focusing on analyzing biomedical data of patients and identifying patterns that reflect the level of pain a patient is undergoing during a medical operation.
- Created machine learning models that predict pain intensity of a specific patient based on visual data from their facial expressions and biopotential data from sensors recording signals in their nervous system.
- Developed a neural network package in the R language that implements a parameterized, multi-layer perception optimized with resilient and classic backpropagation algorithms.
