Join us for an evening focused on how AI agents are moving from experiments to real production work! **Agenda:** **18:00** Gathering, food & drinks **18:30** Sherlock: monday.com’s tickets investigator - The story of an agentic workflow, from POC to production **19:00** First AId Kit **Talk Abstracts:** **Sherlock: monday.com’s tickets investigator - The story of an agentic workflow, from POC to production** What does an agent that actually works on real production tickets look like? In this talk, I’ll share the story behind Sherlock, a supervisor agent that started as a personal initiative, born from identifying a recurring pattern in ticket investigations: data collection, analysis, synthesis, and drawing conclusions. We’ll walk through the journey from a POC built during an internal hackathon, through designing an agentic workflow based on LangChain and LangGraph, writing prompts that embody a way of thinking and an understanding of the product and business context, and integrating with organizational analytics and observability systems. We’ll also cover the real challenges of moving to production: splitting agents by responsibility, context limits, guardrails, human-in-the-loop, architectural changes, and measuring impact. **First AId Kit** What if we could move a big chunk of bug fixing and solving production issues to agentic AI? That would be so cool. In this talk we will go through the end to end process of setting up a background agentic workflow that detects production errors, finds their root causes, assesses the right solution and opens a PR - so you wake up in the morning to tasks almost fully completed for you by your loyal agent. Together We will go over the entire process - the infra challenges, the agentic accuracy issues, and the final result used nowadays in real, massive production environments. Production issues still slow teams down. Finding the root cause is noisy, fixing it is manual, and the cycle continues. But how do you break that loop? In this session, you’ll see how you can wire production context into an AI agent that not only detects failing endpoints, but also traces the root cause, proposes a fix, and opens a pull request automatically. **Bios** **Kamie Shami-Schnitzer - Senior Full Stack Developer** Kamie is an engineering team lead at [monday.com](http://monday.com/) with 5+ years of experience as a software developer, with a degree both in Computer science and Biology from Tel-Aviv university.

**\*\* Join us in Jerusalem \*\*** This meetup will deep dive into how patient-controlled health data and continuous device monitoring are reshaping the future of care. We’ll explore real-world innovations that show how medical-device data, when shared responsibly and meaningfully, can drive impact across clinical, community, and wellbeing use cases. We’ll get a close walkthrough of **Yad Sarah’s SARAH platform**, a next-generation patient-data hub designed to return full ownership of health information back to the patient. SARAH unifies fragmented health records and medical-device data into a secure, patient-controlled system, enabling seamless sharing with clinicians, caregivers, and organizations. You’ll learn how the platform works, what data it supports, and how you can build or integrate your research or product on top of it. You will also hear from leading tech innovators already harnessing continuous medical-device data: ✨ **Buzzy** – Using predictive stress analytics to anticipate mental-health and behavioral changes, reduce treatment burden, and lower reliance on medication through continuous device data streams. ✨ **Neetra** – A cutting-edge medical company combining advanced radar sensing with AI to deliver *contactless* patient monitoring for improved outcomes. **Agenda:** * **18:00 Gathering and refreshments** * **18:30 Opening remarks, MeDs and Yad Sarah** * **18:45** **Personalized Mental Health for elderly population\, using medical devices data and AI modeling \|** Naama Machiah, CEO at Buzzy * **19:15 Inside SARAH: Building a Patient-First Health Data Hub and How *You* Can Leverage It \|** Yitzhak Spielberg, Head of Sarah Advisory Board * **19:45** I**nvisible Care: The revolution of AI and Contactless Healthcare \|** Yair Deitcher PhD, VP R&D at Neetra * **20:15 Mingling and Sweets**

**חשוב! שימו לב יש להרשם לאירוע בלומה דרך הלינק הבא:** **[להרשמה ושריון מקום לחצו כאן](https://tkl.to/tikal-m-meetup-28-1-26)** **Date**: Wednesday, January 28, 2026 **Time**: 18:00–20:00 **Location**: Tikal Offices, Tel Aviv \*The meetup will be held in Hebrew \*Registering through the link above is an application for approval and will be reviewed by our team before tickets are confirmed. As data ecosystems evolve, the transition to a Lakehouse architecture has become the standard for organizations seeking flexibility and scalability. But how do you manage it correctly without being tethered to unpredictable cloud costs or getting lost in file management? In this meetup, we’ll explore the practical side of managing an Iceberg Lakehouse – from building a 100% open-source stack to achieving optimal compaction in Apache Spark. We’ll dive into how to maintain high performance, keep your data organized, and stay in full control of your metadata. 18:00–18:30 → 🍕 Welcome Drinks & Networking 18:30–19:15 → Escape the Clouds: Building a Pure Open Source Lakehouse// Yoav Nordmann, Backend Architect, Tech & Group Lead @ Tikal Are you tired of vendor lock-in and the unpredictable costs of proprietary data warehouses? Join us for a deep dive into building a 100% open-source data stack that doesn't compromise on performance. We will start by constructing a high-performance warehouse including compute, storage, and observability, then expand into a full-scale Lakehouse. Learn how to integrate Apache Iceberg and manage it with cutting-edge tools, ensuring you own your data, metadata, and compute-without the "cloud tax." 19:15–20:00 → Getting Compaction Right in Apache Spark // Ehud Eliaz, Chief Architect and Co-Founder @ DualBird Compaction is a fundamental operation in Spark-based data lakes, yet getting it right is far from trivial. This talk breaks down how compaction is actually performed in Apache Spark and how it is used with open table formats like Apache Iceberg. We’ll focus on the practical side of running compaction at scale: critical configuration choices, Spark's behavior during runtime, and where performance issues tend to appear. Walk away with a clear picture of what “good” compaction looks like in real-world systems. **Important Note:** To help us prepare for seating, please complete your registration on Luma.

## Learn Infrastructure-as-Code (the FUN Way) — Through Minecraft 🎮☁️ **Joint Meetup: Azure CBUS × Columbus HashiCorp User Group** What if learning Terraform and Infrastructure-as-Code didn’t feel like a whitepaper… but more like a game? Join us for a joint Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| “The Azure Terraformer”\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts. In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft servers—while teaching the same patterns you’d use for production cloud infrastructure. ### What we’ll cover * Infrastructure-as-Code fundamentals using **Terraform** * Provisioning real infrastructure on **Azure** * Applying **IaC best practices** (immutability, repeatability, versioning) * How playful environments like Minecraft make complex concepts *click* * Why learning through experimentation beats click-ops every time ### Who should attend * Developers, platform engineers, and cloud engineers * Terraform users (new or experienced) * Anyone curious about Infrastructure-as-Code but tired of boring examples * Minecraft fans who want to see it used in a totally unexpected way No prior Minecraft experience required—just curiosity and a willingness to learn infrastructure the fun way. Come for the blocks, stay for the Terraform. 🧱➡️📐 Want to be a speaker? submit your talk to our Call for Presenters!!! https://sessionize.com/cbus-hug-2026/
