Data Engineers London is partnering once again with the [London Snowflake User Group](https://usergroups.snowflake.com/london/) to bring you a data engineering event in the heart of the City of London this May 🎉 Sign up is either through this Meetup event or on LSUG's event. Agenda is as follows: **6:00pm:** Doors Open & Networking at [Kubrick](https://kubrickgroup.com/) **6:30pm:** Talks Start 🗣️The Speakers🗣️ ***Utilising Snowflake Openflow for Regulatory Reporting*** **Lucie Gamby**, Data Engineer at Entain ([Lucie's LinkedIn](https://www.linkedin.com/in/luciegamby/)) ***Talk Abstract*** Regulatory reporting often comes with a large list of requirements (in our case, an 80-page document full of them) alongside specific and complex business logic as a given. With a large volume of sensitive data to handle, we wanted a solution that would help keep our data within the same environment - hence the choice to explore Openflow as an option to facilitate our delivery to regulators. This session will cover what it took for our team to go from no prior knowledge or experience of Openflow to deploying a production-ready system with it. Demonstrations, What Went Wells, Pitfalls, and what we’d do differently next time! ***Speaker Bio*** Lucie graduated from Lancaster University with a degree in Computer Science in 2023 and joined the Sigma Labs graduate scheme in January 2024. After a 15-week coding fundamentals course, she specialised in Data Engineering, and then placed at Entain in June 2024. Having been exposed to a wide range of tools and platforms since, Lucie has since been tasked with leading the charge for her team to adopt Snowflake Openflow into the tech stack. ***Data Engineering: People, Patterns, Platforms*** **Yomi Bazuaye**, Data, Analytics and ML Engineering Leader ([Yomi's LinkedIn](https://www.linkedin.com/in/yomibazuaye/)) ***Talk Abstract:*** What should *your* data platform *do*? What should it *not* do? How should it harness AI? Stories and examples from building and scaling data platforms across multiple industry sectors and organisations. ***Speaker Bio:*** Yomi is a Data professional with many years of experience in data and analytics engineering. In recent years he has focussed on helping organisations build self-service data platforms, create data products and design and implement a data culture. He has worked within multiple sectors including online banking, e-commerce and supply chain, using multiple tech stacks, including: AWS, Snowflake, GCP, Azure, Databricks.

Full sports hall with 5 courts. **RSVP Required** Everyone attending must RSVP in advance. Members can also confirm by email or text. **Session Fee** £14 per session Includes premium feather shuttles. **Payment** Please pay at the start of the session.

If you haven’t registered, you won’t be able to start playing. Mobile reception in the hall is poor, so if you are set up to pay by bank transfer, you must pay in advance before attending. If we have to chase payment afterwards, the fee becomes £20. Bank transfer is available from your second session onwards once it’s set up and we confirm your playing level fits the standard of the club. Please only attend if you have RSVP’d on Meetup and are able to pay the session fee on arrival or have already transferred in advance. If payment still isn’t settled, you will be removed from the group and blocked from attending future sessions. The same applies to no‑shows who do not release their RSVP within the cancellation policy. **Membership Options** We are a membership‑based club and offer several membership options if a place is offered to you and your playing level fits the club. If membership isn’t for you, pay‑as‑you‑play is also available by RSVP on meetup.

As a guide, Tuesday sessions are for intermediate to strong intermediate ladies, and strong intermediate to advanced men. If you’re unsure of your level, come along — we’ll assess it on court and point you in the right direction. **What’s Included** • Premium feather shuttles (Yonex, Yehlex, Victor) • 5 courts • Fair and organised rotation • Players grouped by level • Optional grade‑based competitive courts in the last 30 minutes when possible. • MatchMaking app available for those who want to track results **Cancellation Policy** Please cancel at least 12 hours before the session.

We are excited to announce our May Community Showcase. This event is an opportunity for individuals at all skill levels to come together and share their experiences with Rust. Whether you’re working on a personal project, contributing to an open-source initiative, or teaching a concept related to Rust, we invite you to present your work and insights. Take this opportunity to build your confidence and share what you are doing. Speakers === **Sang Young Noh** **Talk title:** FerrumMD: Building a Molecular Dynamics Engine in Rust **Abstract:** FerrumMD is a molecular dynamics engine written in Rust, built to explore high-performance scientific computing from first principles. The project implements core simulation components, including Lennard-Jones interactions, periodic boundary conditions, Verlet integration, velocity rescaling, and electrostatics via Particle Mesh Ewald. It aims to bridge computational chemistry, systems programming, and extensible design for future free-energy workflows. **JC Campagne** **Talk Title:** DAGraph: Local reactive graph-based data analytics in Rust. **Abstract:** DAGraph is a reactive node-based canvas app for local data analytics — every cell is a node in a reactive DAG, from basic arithmetic to OLAP-style SQL. Built in Rust, it runs natively or fully in-browser via WASM, with no server and no data leaving your machine. **Darek Luksza** **Talk Title:** Building a streaming technical-analysis crate in Rust **Abstract:** Darek will share lessons from building quantedge-ta, an open-source Rust crate for technical analysis indicators designed for streaming market data rather than batch-only calculation. The talk will cover practical problems around warmup periods, convergence, forming versus closed bars, and stateful updates, plus where Rust helped and where the ergonomics became tricky.

18:00-18:30 - Doors Open/ Registration 18:30-20:00 - Free English Classes in small groups 20:00-21:00 - Meal for £5 Further details: www.freeenglishclasses.org

This will encourage you to use new vocabulary and practise grammatical structures. The group has a limit of 25 people but I usually accept people if you are on the waiting list.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
