🎤 Our January Talks 🎤
Vahid Mohammadi - Lead Frontend Engineer at Accurx - 'Visualising and Enabling Code Migrations at Scale'
Migrating large codebases is challenging. This talk explores how we built tooling to make migrations visible and actionable: custom linting tools to detect deprecated patterns, migration dashboards to track them, and GitHub annotation integration to catch issues in PRs without failing CI during the migration.
Kyle Johnson - Co-Founder at Flagsmith - 'Feature Flags: A Safety Net in the AI Era'
AI's promise - speed and efficiency - is only half true. It's fast, but it's not efficient. Teams still need to comb through, test, and fix AI-assisted code in order to minimise risk. Without feature flags, the bottleneck simply moves. Learn how developers can implement release strategies that remove that bottleneck.
Elena Calvo Carazo - Software Engineer at TryHackMe - 'Models Gone Rogue: Securing AI Integrations'
Your AI features work great... until someone tries to hack them. Unlike traditional REST calls, natural language inputs and unpredictable model outputs expand the attack surface in ways developers don't expect. This talk explores four real-world vulnerability categories (prompt injection, malicious output, denial of wallet, and data spillage) and practical defence-in-depth techniques you can start implementing today to prevent them.
