# โ\*\*[Ariel Shulman](https://www.linkedin.com/in/ariel-shulman/overlay/about-this-profile/) \|\*\* Software Engineer at Factify \| **Postgres Beyond the Rows**
โYouโre likely underutilizing the most powerful piece of your infrastructure.
โWhile most devs treat Postgres as a reliable container for rows and columns, itโs actually a sophisticated engine capable of handling complex data challenges.
โFrom mastering deep, nested hierarchies with lightning-fast traversal to image deduplication and similarity search at scale (no vectors!).
โIn 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 youโre already running.
## โ\*\*[Nadav (Kremer) Beker](https://www.linkedin.com/in/nadav-kremer/overlay/about-this-profile/) \|\*\* Tech Lead at **Finonex**\| **How Observability Killed My Performance**
โLogs, traces, metrics, correlation IDs โ 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, Iโll share real-world lessons from production Node.js systems where adding observability actually degraded performance. Weโll look at the hidden costs of logging, async logging, AsyncLocalStorage, distributed tracing, and high-cardinality metrics โ and why these issues often only appear under real load.

Shut Up & Write!ยฎ at Beit Ariela
Join us for some focused writing time. All writers and all experience levels are welcome and donโt worry, no one will see what you've written. This session is about getting your writing done and meeting other writers in your area.
When you show up, say hello to everyone, grab a drink, and get your writing tools ready. Once youโre all settled, take some time to chat with your fellow writers. Once everyoneโs arrived, I will lead quick introductions and then set the timer for our quiet and focused writing session.
Afterward, weโll have time to chat and get to know each other. We often talk about our successes and challenges as writers. If you donโt have time to stick around, no worries!
**A note about the format**
We donโt host critiques or readings. These events are a safe space for writers of all skill levels and genres to work on their craft, so no one will read or critique your writing.
