QCon London Software Development Conference

🎉 Welcome to QCon London 2025! 🇬🇧 We’re back and excited to bring together senior software practitioners for three days of insightful talks, real-world case studies & deep technical discussions: qconlondon.com Let’s learn, connect, and grow together! #QConLondon

Learning in public under real pressure. That's the current state of the field. Laura Savino (@Adobe Photoshop) opens the final day of QCon London with a keynote on what happens when the pace of change outstrips your ability to feel competent. 🔗 bit.ly/4lsgrUj

Why do the same ideas keep coming back? Holly Cummins closes QCon London on March 18 with "The Free-Lunch Guide to Idea Circularity." Find out more about the keynote: bit.ly/4upY8mC

Most engineering teams are somewhere in the middle of figuring out AI adoption. The Organizations in Flux track at QCon London is built around that reality. Wednesday, March 18. 🔗 bit.ly/4s0Pjhp

The morning ICSAET certification group at QCon London is sold out. An afternoon group on March 19 has been added. Limited places. 🔗 bit.ly/4lk9zbs

Three sessions worth knowing about at QCon London 2026: Sam Newman on cascading failures. Martin Kleppmann on local-first software and cloud sovereignty. Kasia Trapszo on how Netflix's architecture actually evolved. Early bird ends March 10. 🔗 bit.ly/4ud6IVD

Is your team feeling "model fatigue"? Birgitta Böckeler @Thoughtworks delivers a keynote at #QConLondon to help you see the forest for the trees. A high-altitude look at the last 12 months of AI coding assistants and where the industry stands today. 🔗 bit.ly/4b5m99R

Join Chaitanya Bhandari @TigerBeetle at #QConLondon 2026 for: 🔹Vectorized execution & branch-aware operators 🔹Vector search on columnar storage 🔹NUMA-aware computational scheduling 🔹Auto-derived JIT compilers 🔗 bit.ly/4r8M7iA

Join Shawna Martell and leaders from the BBC, Personio, and Carta at #QConLondon 2026 for "The Long Game" track. 🔹 Mastering "boring" problems 🔹 Sociotechnical architecture 🔹 Tech debt in the AI era 🔹 The Influence Toolkit 🔗 bit.ly/40dtUW6

Cloud dependency is now a geopolitical risk. 🌍 Martin Kleppmann, author of Designing Data-Intensive Applications, delivers the #QConLondon keynote on technological sovereignty. 🔹Local-first software 🔹atproto & Bluesky 🔗 bit.ly/4shEdV1

Management playbooks from 5 years ago are hitting a wall. Join Wes Reisz at #QConLondon to rethink engineering teams for 2026. 🔹 Hiring signals 🔹 Broken career ladders 🔹 Cross-stack data ownership 🔹 Agency-led structure 🔗 bit.ly/40B9CWD

Building a production AI gateway shouldn't mean inheriting a massive framework. Join Amit Navindgi @Zoox at #QConLondon to explore Cortex: the "Agents as an API" platform serving 100+ internal clients. Find out more here: bit.ly/3P3E0Gz

20 years of QCon = 20 years of looking under the hood. In 2017, it was Instagram. In 2026, we’re dissecting: 🔹 Netflix: Commerce evolution for 230M+ members 🔹 Nubank: Scaling to 127M users 🔹 Tesco: Architecting a Cloud-to-Edge retail platform 🔗 bit.ly/3OzFfNI

Join Track Host Sid Anand at QCon London for 5 sessions on the new stack: 🔹 Lean Kafka operations 🔹 The rise of the Streamhouse 🔹 S3-to-GPU memory in one copy 🔹 Netflix-scale graph observability 🔹 Chronon’s data processing algorithms 🔗 bit.ly/4axFilE

Kafka API compatibility without the operational headache of ZooKeeper or Raft. 🛠️ Join Peter Morgan, @tansu_io at #QConLondon to explore Tansu: a stateless, open-source broker with pluggable storage (PostgreSQL, S3, libSQL). Streamline your data stack: bit.ly/46nqHGY

Skip the marketing hype. QCon London is about direct access to practitioners who ship. 🛠 Talk resilience with Sam Newman, context engineering with Patrick Debois, or get certified with Luca Mezzalira. 🔗 bit.ly/3OqJDi0 #QConLondon

Governance without bureaucracy. Memory safety without a language rewrite. The Security and Risk Management track at #QConLondon 2026 covers three layers most security conversations skip. Led by Chris Swan, Engineer @atsigncompany. 🔗 bit.ly/4kAXqOY

Is async/await just for I/O? Orson Peters (@Polars) says no. At #QConLondon, Orson shares how Polars uses Rust's async paradigm for computational scheduling, NUMA-aware parallelism, and streaming data beyond memory limits. 🔗 bit.ly/4rQ1oWn

The Architecture in the Age of AI track at #QConLondon covers context engineering, agent authorization, and evaluation beyond benchmarks. Led by Fabiane Nardon, Data Platform Director @totvs. 🔗 bit.ly/4cshmkU

Alfonso Subiotto, Software Engineer @PolarSignals, shares how they use Deterministic Simulation Testing to replay any failure from a single seed. The journey: from WASM in Go to state machines in Rust. 🔗 bit.ly/4qwL8Zn

The pressure to chase every new framework is relentless. And the most impactful engineering work is still the boring stuff nobody celebrates. If that tension feels familiar, the Staff+ track at #QConLondon is for senior ICs navigating the same thing. 🔗 bit.ly/4aj0vzC
