Our March Talks 🌈💻🌍

Erik Rasmussen - Principal Product Engineer, Attio - React Beyond the DOM

It's easy to forget what the creators of React knew from the start: that React is not only for building web pages. Most of us have heard of React Native, that renders to native mobile components, but React doesn't have to render to "components" at all. There's React PDF to generate PDFs and Ink for building UI in the terminal.

At Attio, we've built a way for developers to use React to build plugins for our webapp that render to our custom components, giving us full control over the UI design (the "how"), whilst giving the plugin developer full control UX (the "what").

In my talk, I'll explain what it's like to build a React renderer and reconciler, what they are, and how to use them.

Nick Humberstone - Junior Software Engineer, Actioncy - Breaking into tech in 2025

The job market is always changing, and landing your first role is different today than it was 5 years ago. Nick shares his experience of landing his first role in January this year, the lessons he learned along the way, and what his first couple of months have looked like.

Whether you're looking for your first role, or have already established yourself as a software engineer, there will be something useful for you in this talk.

Ivan Liagushkin - Senior Software Engineer, Twain - AI-Assisted Coding: A Hype-Free Guide

Every day we read about new multimillion-dollar startup being vibe-coded during a weekend hackathon. Or about AI replacing all software engineers by the end of the year.

The reality is different, however. AI tools are here and can dramatically increase dev-team productivity, but they aren't easy to master and they bring new challenges.

In this talk, Ivan will describe the current state of these tools, share best practices, and explain approaches to organise the work of development teams to truly benefit from them.

Our Sponsors

CRMs are at the center of the software stack for millions of businesses. They're ubiquitous and totally essential, yet current products are completely archaic, unloved, and in massive need of an overhaul.

This is software that millions of people use for hours and hours a day – and a $50 billion category – yet you probably can't think of a single awesome piece of software in this space.

Attio is changing that. We’re building a radically new type of CRM that is incredibly flexible and as powerful as the most advanced CRM data models, but also as intuitive, delightful, and collaborative as today’s best software.

Attio is the CRM of the future: a living, breathing platform that connects with a customer’s GTM stack and evolves with them as they grow – from zero to IPO and beyond.
