“...Or how to escape from Management and get back to proper Development!”

This is one person’s journey through 30 years of the IT industry, in an unusually wide range of roles and disciplines. It looks at how to move up, down and sideways across the landscape of what it is we do, and what was learned along the way. So if you’re interested in learning from someone else’s mistakes, come and join me!

🔗 Finish off with Q&A, networking, and 🍻

About the speaker: Graham Cook
Graham has spent many years in the IT industry, in a wide range of roles and sectors from defence and finance, to construction and TechForGood. For the last decade or so, he has been in Software Engineering in both the PHP and JVM spaces, and is particularly interested in 'how' things are done, instead of just 'whether' things are done - though that often tends to be a tricky ask!

Currently exploring Application Security, and how to integrate secure engineering practices into the creation stream, without blocking it…

🗣️ Talk by Opeyemi Folorunsho (🕖 start at 19:00)
In computing, few words are as deceptively simple as "page." We page memory. We flush dirty pages to disk. We traverse B-tree pages. We paginate APIs. We build web pages. The same word appears across hardware, operating systems, databases, distributed systems, and user interfaces, yet it rarely means the same thing twice.

This talk traces the evolution of "page" from its origins in virtual memory to its role in storage engines, buffer pools, write-ahead logs, and modern web architectures. Along the way, we examine how page size encodes hardware assumptions, how page boundaries influence performance and consistency, and how pagination shapes human interaction with data.

By connecting memory pages, disk pages, database pages, web pages, and API pages into a unified mental model, we reveal a deeper systems insight: a page is not merely a data structure, it is a boundary. And boundaries define isolation, locality, latency, and scale.

Attendees will leave with a clearer understanding of how a single abstraction quietly shapes performance engineering decisions across the entire computing stack.

About the speaker: Opeyemi Folorunsho
Opeyemi Folorunsho is a software engineer and technology leader specializing in distributed systems, data infrastructure, and high-performance financial platforms. As Vice President of Research and Development at Moniepoint, he leads initiatives focused on scalable transaction processing, ledger systems, and platform engineering across cloud and multi-cluster environments.

His work spans database internals, consensus systems, storage engines, and large-scale event streaming architectures. He is particularly interested in how theoretical foundations such as information theory, concurrency control, and queueing theory map directly to real-world system performance.
