Ten of the top Summit sessions, replayed live this summer. Free to register. Pick your sessions ↓
In May, a few hundred engineers, architects, and engineering leaders spent three days in Miami at Code Remix Summit working through the same problem from every angle: how to move large codebases forward without grinding delivery to a halt. I watched talks from teams at Netflix, Tinder, Thoughtworks, and a dozen other organizations that operate at a scale where "just upgrade it" stops being a sentence and becomes a multi-quarter program.
The talks were too good to leave in a conference hall. So we are bringing the highest-rated sessions back as live broadcasts through the summer, each one hosted by the speaker who gave it, with real-time Q&A. If you could not get to Miami, this is how you get the content. The first three are scheduled, and more are being added.
What the live event gave attendees, and what these broadcasts give you
The people who came to Miami got something these broadcasts do not replicate, and it is worth being straight about that. Code Remix Summit ran three tracks at once, including a Hack Track where attendees worked hands-on with experts to solve a real problem from their own backlog and left with something they could use on Monday. There were the hallway conversations, the networking, the whole experience of being in the room.
The summer broadcasts are the sessions themselves: the talks that drew the biggest crowds and the highest ratings, replayed live so you can ask the presenter questions in real time. You get the technical content and direct access to the people who built it. You do not get the Hack Track or the in-person experience. If you were in Miami, these broadcasts are a way to revisit the talks you missed while you were in another track. If you were not, they are the next best thing to having been there.
Netflix: getting to confident automated changes across thousands of repositories
Thursday, June 12, 10:00 AM CT
How do you deploy automated changes across thousands of repositories in hours instead of weeks, and get engineers to trust the process? That is the question Aubrey Chipman and Roberto Perez Alcolea, both engineers on the JVM Ecosystem team in Netflix's Developer Productivity organization, take on in this session.
Netflix moved from manual, slow dependency updates to a zero-touch automated process built on advanced dependency management, automated SCM changes, and artifact observability. The harder part was not the automation, it was the trust. Aubrey and Roberto walk through how sharing validation results, feedback loops, and impact analysis got engineers comfortable enough to let platform-driven changes ship at velocity. If you have ever built a piece of automation that worked perfectly and still could not get anyone to merge its pull requests, this one is for you.
Tinder: building the upgrade muscle with OpenRewrite
Thursday, June 26, 10:00 AM CT
Devin Thomson, Director of Engineering for Backend Platform at Tinder, and Ryan Trontz, Technical Lead on the same team, tell the story of how Tinder turned upgrades from a dreaded event into a repeatable capability. They anchor it in two migrations: a first Java upgrade that exposed the limits of manual coordination, and a Java 17 and Spring Boot 3 effort where they leaned hard on automation to keep the change boring and predictable.
The detail engineers will appreciate: Tinder's team authored a custom OpenRewrite recipe to migrate thousands of unit tests from JMockit to Mockito, and finished the effort in roughly a month without widespread manual rework. The session closes on how they combine deterministic refactoring tools with LLMs in a complementary, cost-effective way. It is a clear-eyed look at what it takes to make large-scale refactoring a habit rather than a heroic one-off.
Thoughtworks: the human side of AI and the new bottlenecks
Thursday, June 19, 10:00 AM CT
AI is changing software development faster than most organizations can absorb, and every acceleration creates a new constraint somewhere else. Rachel Laycock, CTO of Thoughtworks, and Kiran Rouzie, Global Head of Organizational Change and Transformation at Thoughtworks, look at where value moves in the delivery lifecycle when AI removes the old bottlenecks.
Their argument is that the new constraints are opportunities for roles that have been easy to overlook, business analysts, QA, and others, to rise in influence, and that the integration of AI into a workforce is as much a human and organizational question as a technical one. This is the session for the engineering leader thinking less about which model to adopt and more about how the team and the org change around it.
More sessions on the way
These three are the start. We are working through the rest of the Code Remix Summit lineup and adding more of the top-rated sessions to the summer schedule, with broadcasts running every Thursday through August. Registering now means you hear about each new session as it is confirmed, and you can pick the ones that fit what you are working on.
Why Moderne runs Code Remix
Code Remix exists because the hard problems in modernization get solved out in the open, by teams sharing what actually worked. That is the same premise Moderne is built on. OpenRewrite, the open-source engine behind a lot of the work these speakers describe, turns code changes into recipes: deterministic programs that run the same way every time, rather than one-off scripts or hand edits. Tinder's custom test-migration recipe is exactly that pattern in practice.
Moderne builds on OpenRewrite and the Lossless Semantic Tree, a compiler-accurate model of a codebase, to give engineers and the coding agents they work with the tools to make changes safely across thousands of repositories at once. The sessions in this series are practitioners describing how they got there. If the problems sound like yours, the broadcasts are a good place to start.
