Work Experience

Data Scientist
September 1, 2023 - Present
In Amsterdam, The Netherlands, I improved forecasting accuracy by building and deploying PyTorch (TFT, Deep AR) models and integrating Chronos-Bolt into production. Built optimized AWS ECR Docker images ensuring full CUDA compatibility for training and inference. Led a seamless migration from PyTorch Forecasting 0.11 to 1.3, resolving compatibility challenges and reducing inference time by 50% compared to the initial baseline after migration, significantly improving pipeline running times. Developed a sub-agent within a multi-agent orchestration system and enhanced the supervisor's ability to route user intents to domain-specific sub-agents.
DevOps Engineer at 4P SA
June 1, 2021 - July 1, 2022
Full-stack development using Java and React. Contributed to a large-scale internal CI/CD platform built on Atlassian products (Bitbucket & Bamboo), integrating pipelines and automating build and deployment workflows.
