Welcome to **GitHub Copilot Dev Days Tel Aviv**, the place where we stop talking about "AI as a chatbot" and start treating it like a specialized member of the engineering team. Most developers use 10% of what GitHub Copilot can actually do. We’re here to show you the other 90%. From architecting complex systems to securing your code against modern threats, this isn't a "hello world" session. We’re bringing together top researchers and engineers to show you how AI-native development actually looks in the trenches. ### **The Game Plan** * **09:30 – Know the Field \|** Doors open. Grab a seat and start talking. * **10:00 – [Adi](https://www.linkedin.com/in/stein-adi/)** \| Welcome Notes * **10:15 –** **[BatEl](https://www.linkedin.com/in/batelzohar/)** \| LLM Testing & Evaluation with Azure AI Foundry * **10:45 – [Marina](https://www.linkedin.com/in/marina-marenkov/) \|** GitHub-Native AI Coding in the Terminal * **11:15 – Coffee & Fuel \|** Quick break. Drink something strong. * **11:30 – [Avihai](https://www.linkedin.com/in/havihai/) & [Matan](https://www.linkedin.com/in/matan-shahar/) \|** Scaling IaC with GitHub Copilot * **12:00 – [Elli](https://www.linkedin.com/in/elishlomo/)** \| Building an Offensive AI with Cli & GitHub Copilot * **12:30 – The Panel** \| Tachles with real\-world Q&A and Debate * **13:00 – Summary & Goodbye** ### **Who should attend?** * **Devs & Architects:** You’re over the hype and want to master complex AI-native patterns. * **Automation Geeks:** You live in the terminal and want to build agentic workflows with MCP. * **The "No-Slides" Crowd:** You prefer live demos and broken code over polished marketing pitches. * **Security Researchers & Red Teamers:** You want to see AI weaponized for vulnerability hunting and exploitation. ###

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.
