- Developed a machine learning model and deployed into production, to classify time series data with 87% F1-score significantly aiding the company in identifying faulty sensors.
- Developed a machine learning model and deployed into production, to forecast the fill level of waste containers, enabling the company to optimize waste collection routes.
- Developed algorithms to mitigate noise in sensor data and improved the event detection, achieving a reduction of false positives by 20% and improving quality of downstream analytics.
- Mentored and trained junior data scientists and engineers, providing guidance and support in their professional development.
Data Scientist/Engineer
10.2020 - 08.2022
- Developed Route Optimization service from the ground up including heuristic algorithms, backend endpoints, REST API integrations with third-party map services. The service is designed to address various scenarios, including solving Capacitated Vehicle Routing problems with multiple refills, or any other subset of the problem.
- Developed and implemented a tailored Capacitated Clustering Algorithm to generate solutions for high-scale Vehicle Routing Problems such as 10,000 nodes.
- Formulated and implemented a Mixed Integer Programming model for a Shift Scheduling Problem using Python and the CPLEX API.
- Conducted analyses for waste collection companies, focusing on capacity planning. Successfully reduced fleet sizes by up to 17% by providing optimized work plans.
- Set up and maintained open-source map engines, eliminating costs associated with proprietary map services.
- Built the data infrastructure, ELT/ETL pipelines using mainly open-source technologies like Dbt, Airflow, Cosmos, Mongodb, Postgresql, AWS, in the absence of pre-existing infrastructure.
- Designed and built a data warehouse, incorporating best practices in dimensional modelling. The warehouse serves both internal reports and customers seeking access to their data directly.
- Delivered impactful insights to customers through the implementation of PowerBI Embedded, solidifying it as a core feature of the product.
- Empowered the hardware team by crafting dashboards for monitoring the health of thousands of IoT devices.
