London business Networking at Mayfair Hay Hill for Directors, Entrepreneurs
**Kindly note that this is a paid event and the average number of attendees for our events is 60-70 people. You can register on [https://www.eventbrite.co.uk/e/london-business-networking-at-mayfair-hay-hill-for-directors-entrepreneurs-tickets-1982669881989?aff=meetup](https://www.eventbrite.co.uk/e/london-business-networking-at-mayfair-hay-hill-for-directors-entrepreneurs-tickets-1982669881989?aff=meetup)**
Network with entrepreneurs and investors at 12 Hay Hill, Mayfair. A premium evening for business growth in London's top private club.
Join leading **entrepreneurs, investors, company directors, and business professionals** for an exclusive networking experience in Mayfair. Hosted at the prestigious Hay Hill private members club, this London Connector event brings together high-level decision-makers to build meaningful relationships, explore new opportunities, and grow their network in a premium setting. Connect with like-minded leaders, spark collaborations, and enjoy a powerful evening designed to elevate your business.
## **Our unique venue is:**
Set in a stunning six-story building at **Berkeley Square, Hay Hill** is unique as it combines the luxury of a private members club with the business focus of a co-working environment, pioneering the concept of the club working, all in the heart of Mayfair.
For our event, we have reserved an area of the venue with a cash bar, so that we can mix and mingle and meet old and new friends, new contacts, and, why not, new clients too!
## **Program**
The format of the evening is 'mix and mingle', meet like-minded business leaders and entrepreneurs and investors in a relaxed environment. Our team is onsite to facilitate meaningful introductions. We connect at a human-to-human level, and prefer building relationships.
## **How many people are attending?**
We have a **maximum capacity of 80 guests** for this venue and given the popularity of our events and the nature of the venue that hosts us, **this one is predicted to be sold out in advance also because on average for each event we run 30-40 places are booked by our members who have joined the yearly membership. Early booking is truly and highly recommended.**
The reason the events we organize are so successful is that we follow a very simple, but effective formula. A couple of days before the event **we create a WhatsApp group with those attendees who wish to start getting to know each other**. This allows each participant to set up meetings with those they wish to meet during (or even before) the event. On the day of the event, you will find a relaxed environment, and a welcoming and supportive crowd.
**Our team will be at the venue to introduce you to anybody specific you'd like to talk to.**
Guests will have access to the part of the Club reserved for our event, but not to other private areas of Hay Hill Club. You can book a private tour though.
**Dress code: business casual (no trainers, no jeans)**
**Refund policy. Tickets bought in advance are generally cheaper than those bought on the day of the event and for this reason cannot be refunded. They can be reassigned to another person of your choice.**
**Event Disclaimer**
Please note that photos and videos may be taken during this event. These may be used on our social media channels and promotional materials to showcase our events.
If you prefer not to appear in any photos or videos, please inform the event host upon arrival, and we will ensure your preference is respected.

**Main Talks**
1. **Agentic Workflows for Data Engineers: How AI Agents Are Changing Our Daily Work** - [Yusuf Ganiyu](airscholar@gmail.com)
Last month, I debugged a critical pipeline failure in 4 minutes that used to take 30. The difference? An AI agent that understands my data infrastructure.
This isn't about replacing data engineers, it's about eliminating the toil that keeps us from high-value work. In this talk, I'll share practical experiments with agentic workflows from my work at AstraZeneca and teaching 20,000+ students at DataMasteryLab.
We'll explore:
* What agentic workflows actually are (beyond the hype)
* Live demo: AI-assisted pipeline debugging with LangGraph
* Practical patterns: Schema evolution, data quality monitoring, self-healing pipelines
* The feature engineering bridge: Helping data scientists love you
* What AI still can't do (and why that matters)
Whether you're skeptical about AI hype or already experimenting, you'll leave with concrete patterns you can implement in your pipelines next week.
2. **Explore the Kingdom - Cursor the Data Engineer** - [Jethro Reeve](jethro.reeve@gmail.com)
I built [explorethekingdom.co.uk](http://explorethekingdom.co.uk/ "http://explorethekingdom.co.uk") over Christmas using Cursor with Opus-4.5 and GPT-5.2 for the data engineering and UI.
I've pulled \~15 Government data sources and have them represented on a map of the UK. This kind of data aggregation tool sells for thousands to niche consultancies. I built it while playing Minecraft on Boxing Day.
What would you use it for? (Why) Is the software world so slow to catch up with the capabilities of vibe coding?

Leaders & Founders: AI in Insurance
**AI in Insurance: Smarter Decisions, Stronger Trust.**
In partnership with Gathered & Found and UnderwriteMe.
Artificial intelligence is no longer a futuristic concept for insurers - it’s a present-day force changing how products are designed, how underwriting decisions are made, how risk is evaluated, and how customers experience insurance.
But for all the excitement, there’s also uncertainty, complexity, regulatory pressure, and a massive gap between what’s talked about publicly and what’s actually happening on the ground.
This event is about closing that gap.
Our panel for the evening:
* **Ben Brown**, CTO, *UnderwriteMe*
* **Chris Mullan**, Head of AI, *CFC*
* **John Walker**, Head of Data & AI Advisor, *Mitsui Sumitomo Insurance Group*
Join **Gathered & Found** and **UnderwriteMe** for a real, in-depth, behind-the-scenes panel discussion with senior leaders who are building, deploying, and governing AI inside some of the most influential players in the insurance ecosystem.
This is not a hype session or chance for vendors to demo their products. This is a real and interactive panel with some of the insurance industries leading minds that are building genuine, real-world AI solutions.
Please attend if you are interested in understanding:
* The real state of AI adoption across insurance
* How decision platforms are reshaping underwriting
* Building trust, transparency, and human oversight in AI-driven systems
* What’s next for insurers, customers, and innovation
* How to deploy AI in your team and business
As always, we will have food and beverages available on the night, with networking opportunities with some of the insurance and financial services industries leading AI and Technology professionals.
*📍UnderwriteMe Offices, Tower Bridge House, St Katharine's Way, London E1W 1BA*
Error-handling in C++26
This month we have a visiting speaker from think-cell, Sebastian Theophil, who will talk to us about error handling in C++26 (with sprinkles of C++23).
We also have space for a shorter talk, or lightning talks. If you would like to speak - even for just five minutes, please drop something into cppldn.uk/speak.
**think-cell** will also be supporting the group by providing pizza and drinks - thanks **think-cell**!
Thanks, also, to **Maven Securities** for hosting us again, this month.
**As usual we'll need your full name for the door list, so we'll be asking for this on registration** (as this may be different to your username).
This data will only be used for the door list/ registration and not published anywhere or used for other purposes.
If you'd like to speak at a future event please get in touch at [cppldn.uk/speak](http://cppldn.uk/speak).
**Here's the approximate schedule:**
**18:30** *Doors open*
**19:00** "Intro and news" - *Phil Nash*
**19:10** *"compile_assert - Compile time C++ assertions" - Jonathan Grant*
I present compile_assert(expression, message), a new C++ keyword proposal for enforcing assertions at compile time within ordinary (non-constexpr) functions.
compile_assert provides advanced asserts at compile time, not runtime. Used for bounds checking, parameter validation and data validation at compile time. All three major compilers (GCC, Clang, MSVC) are supported with a sample implementation. The example implementation does this by using GCC’s attribute error which works with Clang.
**19:25** "Compile-Time Data Layout Transformation with C++26 Reflection" - *Arturs Kalnins*
We’ll use C++26 static reflection and injection to convert an AoS into a SoA at compile time, live on the latest GCC, with zero macros and zero boilerplate.
**19:40** *break*
**20:00** "To Err is Human: Robust Error Handling in C++26" - *Sebastian Theophil*
A walk through the new error handling features in C++26 — including \`std::expected\`, \`std::stacktrace\`, contracts, and more — and how they can help us write more robust, maintainable code.
**21:00** *Conclusion, and moving on somewhere else*

**Predictable Systems in an Unpredictable World (Behrad Babaee, Aerospike)**
Modern systems are challenged by volatility. Traffic patterns shift without warning, workloads evolve continuously, and failures are no longer exceptional events. In this environment, average performance is meaningless. What matters is whether systems behave predictably when conditions change.
This session explores how system design choices determine behavior under volatility. We will discuss why many modern architectures rely on fragile assumptions about steady-state workloads, cache locality, or predictable growth, and how those assumptions break down in real production environments. Through concrete examples and architectural discussion, we will examine what it means to design systems that remain predictable as load, access patterns, and scale evolve.
The goal is not to showcase tools or benchmarks, but to build a shared mental model for thinking about predictability as a first-class system property.
*Behrad Babaee is a software engineer who leads Product Marketing at Aerospike, shaping positioning and go-to-market strategy for real-time data systems in the AI era.*
*He began his career building scalable, distributed applications for organisations including Barclays and Credit Suisse, before moving into architecture and field leadership roles at Aerospike and DataStax.*
*Today, he combines deep engineering expertise with strategic product leadership, focusing on how organisations design systems that remain predictable, resilient and performant under real-world volatility.*
**Observability with HAProxy: detecting what is not working and why (Baptiste Assmann, HAProxy Technologies)**
Is it the network, the app, or the database? In complex microservices environments, "mean time to innocence" is a critical metric for platform engineers. HAProxy sits at the convergence of these traffic flows, providing a unique vantage point to answer the ultimate observability question: "WTF is going on?".
We'll do a deep dive into the metrics that matter, so you can detect anomalies before users complain. You will learn:
* The difference between monitoring and observability in a reverse proxy context.
* How to access HAProxy’s detailed logs, stats, and stick-tables.
* How to analyze the "life of a request" using precise timers to pinpoint latency sources.
* How to use HAProxy’s observability features to fix real-world issues (demo)
* How HAProxy Fusion provides centralized observability and automation for enterprise deployments at scale.
*Baptiste Assmann is Director of Product at HAProxy Technlogoes. He spent his carreer on networking and high performance architecture. Today, he plays a key role on HAProxy's ecosystem evolution: from bare metal to Kubernetes and from load balancing to advanced security at scale and always looking forward for what's next!*
**eBPF: Revolutionizing Cloud-Native Security (Alam Ahmed)**
eBPF: Revolutionizing Cloud-Native Security from the Kernel Up
Cloud-native architectures have fundamentally broken traditional security models. While 67% of organizations now delay deployments due to Kubernetes security concerns, conventional tools remain blind to the dynamic, ephemeral nature of containers—operating from the outside looking in, missing critical kernel-level threats until it's too late.
This session reveals how eBPF (extended Berkeley Packet Filter) is transforming cloud-native security by moving visibility and enforcement directly into the Linux kernel. Through real-world case studies from Meta, Google, and Cloudflare—where eBPF processes billions of packets per second and mitigates multi-terabit DDoS attacks—you'll discover how this technology delivers 10x performance improvements with <1% CPU overhead.
We'll explore the production-ready CNCF ecosystem (Falco, Tetragon, Cilium) and demonstrate practical security observability patterns: process execution monitoring, network correlation with Kubernetes context, file integrity tracking, and syscall anomaly detection. No kernel modules. No code changes. Complete visibility.

"The Enchanted Greenhouse" by Sarah Beth Durst
Come join us for coffee at Matari Coffee to discuss our March book, "The Enchanted Greenhouse"!
Book description:
Terlu Perna broke the law because she was lonely. She cast a spell and created a magically sentient spider plant. As punishment, she was turned into a wooden statue and tucked away into an alcove in the North Reading Room of the Great Library of Alyssium.
This should have been the end of her story . . . Yet one day, Terlu wakes in the cold of winter on a nearly-deserted island full of hundreds of magical greenhouses. She’s starving and freezing, and the only other human on the island is a grumpy gardener. To her surprise, he offers Terlu a place to sleep, clean clothes, and freshly baked honey cakes—at least until she’s ready to sail home.
But Terlu can’t return home and doesn’t want to—the greenhouses are a dream come true, each more wondrous than the next. When she learns that the magic that sustains them is failing—causing the death of everything within them—Terlu knows she must help. Even if that means breaking the law again.
This time, though, she isn’t alone. Assisted by the gardener and a sentient rose, Terlu must unravel the secrets of a long-dead sorcerer if she wants to save the island—and have a fresh chance at happiness and love.
CBusData - Discover the Power of Window Functions
Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems:
* Using running totals
* Performing operations in intervals
* Identifying data gaps and islands
* Performing aggregates without losing detail
Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
Go Build & Learn
Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free!
This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
