The TLV PUG is back! Join us for an afternoon of talks, food, drinks, and good company at Microsoft Reactor Tel Aviv on Level 50 with those incredible skyline views. This time we've got two great talks lined up. Oh, and there will be swag. You're welcome. **Talks:** **From Zero to AI Agent: Building with Microsoft Foundry Agent Service** *[Engin Diri](https://www.linkedin.com/in/engin-diri/) \- Senior Solutions Architect\, Pulumi* AI Agents are everywhere right now, but how do you actually build and deploy one without losing your mind? In this talk, Engin will walk through how to use Microsoft Foundry Agent Service together with the Microsoft Agent Framework and Pulumi to spin up, configure, and manage AI agents, all as code. We'll go from an empty project to a working agent, covering the gotchas and the good parts along the way. **OpenClaw Bots Done Right: No Security Nightmares Included** [Dor Serero](https://www.linkedin.com/in/dorser/) \- Principal Architect\, Microsoft So you want to run an OpenClaw bot, or any agent for that matter. Cool. But have you thought about what happens when things go sideways security-wise? In this session, Dor will share real-world lessons on running OpenClaw bots without the kind of setup that keeps you up at 3 AM wondering if something just went horribly wrong. We'll cover common pitfalls, hardening tips, and practical patterns to keep your bot humming without opening the door to trouble. **Schedule:** * 5:00 PM — Doors open, food, drinks & networking * 5:30 PM — From Zero to AI Agent: Building with Microsoft Foundry Agent Service (Engin Diri) * 5:55 PM — OpenClaw Bots Done Right: No Security Nightmares Included (Dor Serero) * 6:20 PM — Networking, food & drinks * 7:30 PM — See you at the next one! **Where:** Microsoft Reactor Tel Aviv Menakhem Begin Rd 144, Level 50 Tel Aviv-Yafo After the official wrap-up, we'll continue any interesting discussions at a nearby bar for those who want to keep the conversation going. Spots are limited, so grab yours early. See you there!

***\*\*To register for the meetup, please register via Luma using the link below\*\**** Register via Luma -> [https://luma.com/sszyn5y0](https://luma.com/sszyn5y0) # ​**18:00 - Mingling 🎉, pizza 🍕, and beers 🍻18:30 - lectures**20:00 - Go Home!------------------------------------------------------------ ​ **Gal Lerman \| Tech Lead \| Papaya** **One Process to Rule Them All: How We Killed Our Microservices — for Testing, Dev Envs, and Local Development** ​Microservices are great in production. Everywhere else, they're expensive, slow, and painful. We'll show how we collapsed our entire service fleet into a single process — first to replace our mock-heavy tests with fast, real E2E tests that boot every service in-process; then to slash Kubernetes dev environment costs by replacing a pod-per-service with a single pod; and finally to enable fully local development with instant feedback, zero deploy cycles, and real debugging. Same architecture, three wins. ​ **Stav Levinger \| Senior Full Stack Engineer \| Riskified** ​Unblocking the Node.js Event Loop: Real-World Troubleshooting In a NodeJS Consumer ​What happens when a perfectly healthy and robust Node.js service suddenly stops responding, fails its health checks and gets killed by Kubernetes? ​In this talk, I’ll share a real production incident from a high-throughput, Kafka-driven system, where a single consumer began collapsing under unusually large datasets. ​What initially looked like a routine performance issue quickly turned into a deeper investigation: growing lag, stalled processing, misleading signals, and a bottleneck hiding far from where we first looked. ​We’ll walk through the debugging journey step by step, examine practical profiling techniques to narrow down the search, and ultimately uncover the real root cause. ​**Or Kaplan \| Director of Engineering \| Remitly Israel** ​Implementing Distributed locking algorithms in Node.js ​Description ​Protecting shared sensitive shared resources from race conditions is hard enough when running in a single process. Let's make it harder: how do you do it in a distributed system? Scale it up and run it in a production system that serves millions of transactions. See where we’re going here? ​In this talk, I will take you along our journey of implementing distributed locks in Node.js, how they broke, and how we evolved our algorithm over time to support thousands of requests per second in a mission-critical financial system. We will discuss different ways to implement distributed locking, using different tools and approaches. Learn how to improve performance to support more than 10,000 transactions per second which are all trying to access the same resource while running workflows on multiple data centers and how to verify it doesn’t break. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ​​ Kindly be informed that attendance at the meetup is on a first-come, first-served basis until capacity is reached.

Join us at Unity of Columbus for our Weekly Reiki Share, a peaceful and uplifting gathering for connection, healing, and growth. A Reiki Share is a time where Reiki practitioners and students come together to give and receive healing energy in a supportive and welcoming environment. These sessions will be moderated by Columbus Unity Reiki. Reiki is a hands-on energy healing method from Japan that first came to the United States in 1938. Since then, it has grown in popularity and is now widely practiced throughout the West. All levels are welcome, and you do not need to be a practitioner at Unity of Columbus to attend. If you are a Reiki practitioner, a Reiki student, or simply interested in becoming a Reiki student, we warmly invite you to join us. Come practice your healing techniques, learn new approaches, receive healing energy, and connect with a like-minded community in a space of relaxation, renewal, and positive energy.

At Evolve Synergy Sessions, you'll be part of a supportive mastermind where we share challenges, brainstorm solutions, and inspire one another to take bold steps in our businesses. Grow your network, gain fresh perspectives, and build meaningful relationships with like-minded women who are committed to success. Whether you’re looking to move the needle in your business or simply need a space to connect and recharge, this is the perfect place to fuel your entrepreneurial journey.
