About

With extensive experience in data science and machine learning, I specialize in creating advanced models for natural language processing (NLP) and computer vision (CV). Currently, I am a Senior Data Scientist at CCCIS, where I develop machine learning models for tasks such as single shot image classification and named entity recognition. I also work on image-to-text models like CLIP and BLIP and have developed a chatbot based on the GPT-4 model. My role involves collaborating with insurance industry experts to identify needs and develop assumptions for models that support their work. Previously, I worked at Cortical.io, where I researched and developed deep learning models, including convolutional and custom transformer models. I also set up distributed computing environments and trained models using Horovod. At Parkspace.ai, I focused on data engineering and machine learning models for predicting parking space occupancy. My experience at SII Poland involved creating ML models for NLP, developing internal ML solutions, and assisting with recruitment for the ML/AI team. As a Junior Data Scientist at Lingaro, I developed machine learning and deep learning solutions for various applications, including NLP, CV, and forecasting. My educational background includes a Bachelor's degree in Computer Science and another in Philosophy from UMCS, Lublin.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
