What we’re about
The London Java Community (LJC) is a group of Java Enthusiasts who are interested in benefiting from shared knowledge in the industry. Through our forum and regular meetings you can keep in touch with the latest industry developments, learn new Java (& other JVM) technologies, meet other developers, discuss technical/non technical issues and network further throughout the Java Community.

What is the LJC?
The LJC is an official Java User Group for developers based in London. It was founded in November 2007 and since then has grown to over 5000 members and is now the biggest Java User Group in the UK.
What goes on in the LJC?
We run a variety of regular events ranging from social events and technical presentations to our full day unconference. On top of the events we run prize draws and have an active mailing list/forum. We support the Graduate Development Community in London and promote London based Open Source Software projects where possible.
Who can join?
Membership is restricted to Java developers working in or around London (or those hoping to train in Java, or relocate to London). Membership will not be granted to those involved in the recruitment industry.
Is there a fee to Join, is there a fee for the events?
It’s completely free to join and 99% of our events are completely free. The only event which is charged for is the Unconference, the charge is minimal and it is there to cover refreshments on the day.
How do I join?
Just click on the link on this page to sign up to the mailing list, you'll hear of all of our latest news and events and can take part in the monthly prize draws.
Do you have to go to every presentation?
Absolutely not – it’s completely up to you which events you attend and which you don’t. Every event attracts a different crowd.
Where are the events held?
Europe's Premier technical training company, Skills Matter (Barbican) sponsor most of our events by providing the venue.
Can I read some member feedback?
We have been collecting feedback for the last few years from our members you can read it here: https://www.meetup.com/Londonjavacommunity/about/comments/?op=all
Can I give a presentation to the LJC?
We run various in-person and online events, and welcome highly experienced speakers, all the way through to those just starting out. If you have a presentation you'd like to submit for consideration, please visit https://sessionize.com/ljc

Please register on Eventbrite to join this event.
About this event
The LJC is delighted to continue our new series of events, aimed at giving all Community members an opportunity to present at an LJC meet-up.
If you have an interesting topic to share, these events are for you. You don’t have to be an experienced speaker - we want to hear your story and offer you a friendly, informal platform to practise and improve your presentations.
For attendees we want this to be a meeting place, where you can talk and network with other technologists in London.
If you’d like to speak at a future event, please submit your talk and bio details here: https://sessionize.com/ljc/
Huge thanks to our friends at Elastic for hosting this event and supporting our Community.
Speaker One:
Carly Richmond - Developer Advocate & Manager @ Elastic
Talk: How to Destroy a Software Engineer@Retaining Software Developers is a significant challenge for teams. According to the Infragistics Reveal Survey, 37.5% of respondents expected difficulty in finding developers in 2023. To retain talent and keep DevOps engineers happy, we need to know how to make them unhappy.
Join me as I discuss antipatterns in management, development, testing and monitoring patterns that can stop you retaining awesome software engineers.
Outline
- I’ll cover:- Alert volume evaluation, and how we alert bombardment leads to burnout and alert fatigue. I’ll also cover best practices for on-call rotation and BYOD usage to stop engineer burnout even when they’re not on call.
- SLO and metric comparison across teams, and how comparing team metrics rather than improving metrics such as DORA over time for a single team breeds animosity and demoralises engineers.
- Code reviews with jerkish or unhelpful comments, and the difference between radical candour through constructive feedback and pulling people down.
- Tool overload, and how selecting a common toolbox reduces the need for context switching.
- Flaky or poor testing, and how it builds mistrust and apathy in platform quality.
- Constant work items and a lack of learning time, and how a lack of training opportunities and space to grow leaves engineers feeling stuck.
- Lack of support for conference attendance and speaking, and how community connections help engineers grow and learn.
Speaker Two:
Alisher Alimov - Software Engineer at NVIDIA
Talk: Transition to a reactive architectureThe presentation is focused on practical aspects of transition to reactive architecture. It discusses the problems of processing large volumes of requests and managing distributed services. The presentation emphasizes moving from traditional blocking operations to non-blocking, asynchronous processes to improve scalability, fault tolerance, and performance.
Key points include:
- Introduction to Reactive Architecture: Understanding the need for a scalable and fault-tolerant architecture that efficiently handles client requests while minimizing errors.
- Reactive Architecture Solutions: Discusses how the principles of reactive architecture, including non-blocking I/O, event-driven programming, and microservices, address these challenges, resulting in more efficient resource utilization, reduced latency, and improved overall system performance.
- Practical Applications: Examples of reactive architecture implementations in real-world scenarios, especially in environments requiring high parallelism and low latency processing.
- Challenges in transition to reactive architecture
The goal of the presentation is to educate the audience on the benefits of moving from blocking operations to a more efficient, reactive approach, ultimately leading to more responsive and scalable systems.
This event is organised by RecWorks on behalf of the London Java Community.

Title:
From Diapers to Delivery: Parenting Lessons for Effective Management
Synopsis:
Parenthood often arrives with little time for preparation. Our idea of 'good' parenting usually involves emulating what we’ve observed in others, whilst hoping we won't do any permanent damage our kids.Stepping into a managerial role can feel remarkably similar: we often have to rely on mimicking behaviours we’ve seen in others, despite knowing this may be imperfect or uncomfortable.Fortunately, there is a science to becoming a better manager, and we can draw inspiration from our experiences as parents (or children).In this talk I hope to provide you with a systematic method for improving your approach to management, so you can get closer to being the manager you most want to be.Speaker Two: Marcin Kruglik
Title:
Jakarta EE 101
Synopsis:
Jakarta EE still carries a lot of baggage from its Java EE days — that it’s outdated, not responsive, and no longer relevant because "everyone has moved to Spring." But are these opinions actually based on facts and a real understanding of the project?In this talk, we’ll explore what Jakarta EE really is — and probably more importantly, what it’s not.
Is it a competitor to Spring? Is it still relevant today? What’s its relationship with MicroProfile? How many of us are actually using Jakarta EE in our projects?
And finally, is there anything new happening in Jakarta EE?This event is organised by RecWorks on behalf of the London Java Community.
