QCon London 2023 is a wrap!

Thank you to the 1,150 senior software engineers, software architects, and team leads who joined us at QCon London 2023. Take a look at the conference highlights. Catch up with the session videos you missed. See what people had to say on social about #QConLondon. Over 75 software leaders driving innovation and change shared their practical insights and use cases to help attendees validate their technical roadmap. QCon London attendees told us how the event helped them find solutions to their challenges, adopt the right software innovations and practices, and reduce uncertainty on which technologies should be part of their roadmap. Join us at our next QCon London international software development conference (April 8-10, 2024).

QCon London focused on emerging software trends and innovations

Technical talks from over 75 software domain experts focused on innovation and change. Talks focused on patterns & practices, not products and pitches.
Attendees learned implementable ideas they could apply after the event.

Take a look at the event highlights and see what your peers had to say on social media about #QConLondon.

My first time at the #QConLondon! Some colleagues had already told me about its majesty, but you know - in St. Thomas style - if you don't see it, you never believe it 100%! :smile: Well what can I say... 15 different tracks spread over 3 days, for a total of 75 talks. An impeccable organization with obsessive attention to detail and attention to inclusion beyond imagination...

Another grey rainy day in London? No, it is a 2nd day of #QConLondon! I never thought I would attend one of the most important engineering conferences in the world, but here I am, a first time attendee 😊

QCon is like the SuperBowl of technology conferences - expertly curated tracks, aimed at experienced individuals - it's a wonderland for learning, meeting people, and just celebrating technology and the innovations in our industries. I leave the event with many things that I can take back and improve when back at work as well as being energised again. From the quality of the talks, the venue and organization, and the best keynotes daily, it's the highlight of my conference year!

It is all content and no fluff. There are no thinly veiled presentations touting a vendor's products, but actual talks by professionals like me who are tackling problems like me.

Alex White
Enterprise Architect - Digital @ASOS

QCon content is a great balance of technical detail and thought-provoking ideas that provide inspiration for the workplace.

Mark Bursnall
Head of Engineering @Commify

QCon is a fantastic conference that has given me a renewed excitement in leveraging new innovations, technologies, and approaches to solve the challenges faced in my day-to-day role.

    Architectures You've Always Wondered About

    The biggest software systems on the planet need sophisticated architectures, deliberately and carefully designed to support true planet-scale, along with high availability, durability, security, and many other concerns.

    Building Modern Backends

    Creating backend architectures is a more demanding task than ever, with many questions to answer, such as: how to build and operate services that are reliable and secure, scale to millions of users, and are maintainable too? How do you ensure data is always up-to-date and accessible with low latency? Which consistency models can be leveraged to achieve a good balance of performance and user experience? How to keep your systems observable, and how to establish governance and discovery for synchronous APIs as well as streaming services?
