Daniel Clayborough | Frontend Team/Tech Lead at Agora | Standardizing Large JS Codebases in the AI Era

​By pushing decisions into tooling, we made our TypeScript codebase predictable and consistent. This talk explores how strict mode, opinionated linters, generators, tests, pnpm, and CI guardrails removed countless micro-decisions, simplified legacy migrations, and improved day-to-day developer experience.

​Ariel Shulman | Software Engineer at Factify | Postgres Beyond the Rows

​You’re likely underutilizing the most powerful piece of your infrastructure.

​While most devs treat Postgres as a reliable container for rows and columns, it’s actually a sophisticated engine capable of handling complex data challenges.

​From mastering deep, nested hierarchies with lightning-fast traversal to image deduplication and similarity search at scale (no vectors!).

​In this session we will move beyond standard queries to show how built-in indexing and specialized data types can replace external microservices, and simplify your stack. Come see why the most powerful tool in your stack is likely the one you’re already running.

| How Observability Killed My Performance

​Logs, traces, metrics, correlation IDs — observability promises clarity when systems get complex. But in Node.js, these tools are not free, and used without care they can become a serious performance bottleneck. In this talk, I’ll share real-world lessons from production Node.js systems where adding observability actually degraded performance. We’ll look at the hidden costs of logging, async logging, AsyncLocalStorage, distributed tracing, and high-cardinality metrics — and why these issues often only appear under real load.
