The Lineup for the evening

Talk 1: Building Delivery Hero’s Product Semantic Similarity Using Real-Time Vector Search
Abstract: Delivery Hero's Quick Commerce service offers a convenient way for customers to order items from grocery stores for delivery. However, the Marketplace has thousands of stores and millions of products. The company risks revenue loss and churn if Customers cannot easily find products that match their needs and preferences. In this talk, we will explore how Delivery Hero developed a Product Semantic Similarity recommender to identify Similar Products in multiple touchpoints of Customer's purchasing journey, by using Transformer-based product embeddings and Atlas Vector Search.

Speaker: Fahad Yousaf
Bio: Hailing from Pakistan, I am a Machine Learning Engineer at Delivery Hero. My previous roles include working at i2c Inc., and Turing. Over the course of my career, I have developed and productionized a range of machine learning applications, such as Call Transcription Analytics powered by Natural Language Processing, Mobile Remote Deposit Cheque processing using Computer Vision, Semantic Search systems etc. Outside of work, I enjoy learning about the mysteries of the universe.

Talk 2: Introduction to the open-source world: It's all just a series of gifts!
Abstract: The Python community is an incredibly welcome and diverse community, open to people from all backgrounds and of any experience level. With a vast variety of projects to get involved with, it can serve as your point of entry into the world of open-source software, whatever your interests might be. From PyGame for gamers interested in game engines to NumPy for data scientists and mathematicians, it's got something for everyone.
In this talk, we'll set out on a journey through the different parts of the Python community and we'll use that to discuss ways to get started with open-source software, get a better idea of what makes a good contributor and hopefully give everyone a better picture of what to expect when getting into this very exciting world.

Speaker: Lysandros Nikolaou
Bio: Lysandros works as a Senior Software Engineer at Quansight Labs. He is a CPython core developer, specializing in the parser, the tokenizer and the REPL. He recently worked on supercharging f-strings in Python 3.12, the new REPL for Python 3.13 and introducing fast string ufuncs in NumPy 2.0. Currently, he's mostly dealing with improving support for free-threaded Python in the PyData ecosystem.

Lightning talks
There will be slots for 2-3 Lightning Talks (3-5 Minutes for each) between the two main talks.
