ElixirConf® EU 2026 in Málaga is a two-track hybrid conference with 20- and 40-minute speaking slots including optional Q&A.

Do you have knowledge or experience with Elixir and its rapidly evolving ecosystem? We're seeking speakers focused on the areas where Elixir and high-impact application development truly shine, exploring advanced techniques, real-world scaling challenges, and the integration of emerging technologies. We seek talks that are technically deep, practical, and heavily oriented toward building robust, maintainable, and highly concurrent, distributed systems.

CFT deadline: 6 January 2026.

Need talk ideas? Here are some topics to spark your creativity:

We're focusing on the areas where Elixir and high-impact application development truly shine, exploring advanced techniques, real-world scaling challenges, and the integration of emerging technologies within the ecosystem. We seek talks that are technically deep, practical, and heavily oriented toward building robust, maintainable, and highly concurrent systems.

Core Phoenix & Application Architecture: 

• Deep dives into Phoenix Contexts and Boundaries, advanced strategies for managing application state using PubSub, Registry, and integrating OTP patterns (GenServers) within the Phoenix structure.
• High-Performance Phoenix: Talks on optimizing endpoint performance, efficient data serialization, minimizing latency between client and server, and leveraging new BEAM features for speed and reduced latency in I/O bound tasks specifically within a Phoenix application 
• Testing and Maintenance: Advanced strategies for Ecto testing, comprehensive LiveView testing patterns, using property-based testing, and ensuring long-term maintainability in large, evolving Phoenix codebases.
• Advanced LiveView Architectures: Beyond the basics - showcasing large-scale LiveView applications, patterns for complex component design (including new features and Hooks), and advanced techniques for optimizing the browser-server communication layer. We are particularly interested in JavaScript interop best practices and Elixir in the browser (e.g., Hologram, Popcorn), Rust Interop.

AI & Data Landscape:

• Elixir in GenAI & Machine Learning: Practical applications leveraging Nx for scientific computing, integrating AI/ML models directly into BEAM applications, processing real-time data streams for large language models (LLMs), and exploring local AI inference and whisper integration as application features.
• Data & Streaming Pipelines with Ecto/Oban: Using Broadway, Flow, and Oban to handle massive data processing, event sourcing, and high-throughput background job execution, with a strong focus on *robust data persistence and transactional integrity via Ecto.
• Embedded and Edge Networks: Explore how Elixir, through Nerves and the AtomVM is transforming edge and embedded systems—from IoT devices to real-time data processing at the network’s edge. We’re looking for talks that showcase innovative architectures, tools, and experiences bringing Elixir’s reliability and concurrency to constrained or distributed environments.

Ecosystem, Operations, and Future Trends:

• Real-World Case Studies & ROI: Compelling stories from companies that have successfully scaled with Phoenix, detailing the business value, Return on Investment (ROI), and lessons learned from migrating legacy systems to the Phoenix stack, including use cases for Nerves (IoT, embedded systems).
• Modern DevOps & Observability: Best practices for deploying Elixir/Phoenix applications in Cloud Native environments (Kubernetes, Nomad), advanced Telemetry and tracing, and innovative tooling for profiling and monitoring in production.
• Community & Developer Experience: Insights into improving the Elixir Developer Experience (DX), effective team onboarding, fostering open-source contributions, and the future evolution of the language design.

RECOMMEND A SPEAKER

We want to make sure our conference is as diverse as the community we represent. Do you know any researchers, programmers or experts who are a part of groups traditionally underrepresented in IT (due to gender, ethnicity or any other reason) and whose work you can recommend to our committee? Please, let them know, that our CFT is open and that we’d love to see their work! Also, you can suggest their name in the form.

IMPORTANT DATES

• Your talk should be submitted by 23:59 CET on 6 January 2026.
• You will be informed about the status of your submission by 15 January 2026.
