Introduction
I am a research-trained physicist turned Machine Learning Engineer, with strong foundations in mathematics and programming, and over five years of hands-on experience delivering computer vision and ML systems in startup environments. My background allows me to bridge research and production: I am comfortable designing and training advanced models, as well as turning them into robust, scalable solutions integrated into real products.

Applied data analysis techniques to enhance training datasets and gain deeper insights into model performance, leveraging expertise in image and color science. Trained and fine-tuned multi-task machine learning models with architectures such as ResNet, ViT, and Swin Transformer. Deployed machine learning models efficiently using data versioning (Git+DVC), experiment tracking (MLflow), and scalable APIs (FastAPI). Specialized in training image quality models with mixed-bit-depth images (HDR and SDR), optimizing performance for real-world viewing conditions.
