Hey! I'm Hania Jarlaczyńska, an AI Engineer. I've been in the AI space for the past 6 years, moving through different roles: from research, through strong client-facing work, to productizing AI solutions at the scale of millions of products. I also enjoy talking about it at conferences.
When I'm not in front of a computer, I run, cycle, and train gymnastics.
Collaboration? Let's get in touch.March 2025 - Present
Co-developed Tesco's Product Intelligence platform, enabling internal teams to operationalize AI at scale. Designed, evaluated, and productionized GenAI solutions using Retrieval-Augmented Generation and few-shot prompting, supporting enrichment of over 1M products in a live system. Built and maintained backend services in Python and Java, deployed via Docker and Kubernetes on Azure. Worked with PostgreSQL and Couchbase, with observability and incident handling through Splunk and Zendesk.
January 2024 - March 2025
Delivered custom, production-grade AI solutions for enterprise clients using Palantir Foundry and Large Language Models, including systems supporting carbon footprint calculations. Designed and implemented a Generative AI chatbot on Microsoft Azure using Retrieval-Augmented Generation. Built end-to-end applications with Python, FastAPI, Bicep, and React, covering backend services, infrastructure as code, and user-facing interfaces.
July 2022 - December 2023
Worked on deep learning frameworks with a focus on Graph Neural Networks. Contributed to path-based GNN solutions in DGL, achieving up to 4x speedup, and benchmarked distributed GNN training on AWS. Improved MXNet with operator fusion and quantization. Collaborated with internal teams and clients, delivering presentations and technical knowledge-sharing sessions.
Computer Science and Intelligent Systems, 2020 - 2025
