An AI skill can match a request perfectly - and still be impossible to execute. @AshkenaziOrtal’s new @arxiv paper explains how @Wix's Helpmate checks account state before skills reach the LLM. Across 756K+ production messages, this filtered out 59.4% of matched candidates and reduced skill context by 90.5%, saving 228.8M tokens. At @Reversim Summit 2026, Ortal will explore this approach as part of her talk on designing, routing, and scaling AI skills in production. Read the papert: arxiv.org/html/2608.01050v1

Building with AI is getting easier. Understanding why it worked - and making it work again - is the harder part. On Nov 2, Amir Harel (Symphony by @Wix) will take the stage at the Claude Community meetup at Wix Campus, TLV, to show how a real feature evolved from a successful experiment into a repeatable process. Good luck, Amir! Details & RSVP: luma.com/claude-9ja6

How do you move critical 🚩 production databases between clusters while millions of users keep using the applications that depend on them? At @Wix, we needed to solve this to improve reliability: when applications share a database cluster, a problem in one can affect the others. Bar Shauli shares how she and our Wix Data Infrastructure team built an internal migration service using Kafka and ProxySQL on top of MySQL, allowing databases to move safely between clusters with zero downtime. From streaming data and handling partitioning challenges to switching live traffic, here's how we make database migrations happen at massive scale-without users noticing. 👉 Read her great blog post: wix.engineering/post/how-we-…

Components help developers manage complexity. But what happens when AI agents have to navigate the boundaries we created? Scattered files, slots, and context can force agents to reconstruct a page before they can safely change it. In this article, @yoavabrahami explores how Jay, a new frontend framework, approaches that challenge through regions: keeping markup local and editable while sharing the underlying logic. You’ll learn how template flattening moves composition from runtime to coding time, how targeted updates keep pages reactive, and how validation and sync preserve local edits as templates evolve. Read here: wix.engineering/post/compone…

What does it take to build agentic products on open-weight models? @ittaiz is speaking at @NVIDIA GTC Berlin 2026! 👏 He'll join a panel exploring why builders are moving to open-weight models, the trade-offs in cost, latency, and quality, and what it takes to run them safely at scale - including what stays on closed models and why. Good luck, Ittai!

What does it take to make on-call better - and turn production incidents into lessons that stick? In "How to Win in Production" Guy Nahum walks through real incidents we've faced at @Wix, the failure patterns they exposed, and the changes that helped us reduce noise and learn without blame. Watch this talk for practical rules and habits you can bring to your team, plus a grounded look at where AI can responsibly help: youtu.be/CaNuUuMsh1k?si=f5wM…

Proud to see @gilecks sharing his expertise at @ReactAdvanced London 2026! 👏 Gil will explore how React 19s use API can help improve application performance by controlling when resources load, components render, and pages become interactive. Don't miss his session! reactadvanced.com/

For the first time, we're hosting a Claude Community meetup at @Wix Campus, TLV! Join the meetup on November 2 to examine the decisions behind building with AI: how to define a problem worth solving, judge whether your solution delivers real value, and turn successful experiments into reliable systems. Three talks with practical lessons: >> Amir Harel (Symphony by Wix) will show how to build the smallest useful version, evaluate it, and turn successful experiments into repeatable results. >> Guy Aga will walk you through building a real product and business, from market research and product development to launching an online store with Claude Code. >> Tali Despins will explore how to learn beyond your expertise, work through the discomfort of being a beginner, and combine skills across disciplines. 📍 Wix Campus, Tel Aviv 📅 November 2, 17:00 Limited spots available.

[ 👋 Meetup] Large-scale migrations are never just about moving code or infrastructure. They're also about doing it without slowing 🚩 everyone else down. At @Wix, two very different migration challenges required two different approaches: 1. Rolling out automated code changes across hundreds of codebases, while keeping developers focused on day-to-day work. 2. Moving 1,000+ MySQL servers across 160+ clusters, multiple regions, and two major platform transitions - all within 30 days and with zero downtime. @Danaavital58 and Shmuel Mekonen will share how these migrations were designed and executed: the architecture, the automation, the tradeoffs, the failures along the way and the key decisions that helped them succeed. Join us on Nov 1 at Wix Campus TLV - RSVP here: wix.engineering/migrations-a…

מאד (מאד) גאים באורטל אשכנזי ובגיא נחום שהתקבלו ל- @reversim וידברו שם על בניית סוכנים בפרודקשן ועל גיוס המפתחים שיבנו את הדור הבא! 👏👏 אל תפספסו את ההרצאות שלהם >> אורטל תציג מה קורה כשסקיל של סוכן AI הופך למאות. איך מגדירים את היכולות, מזהים תקלות נפוצות ומנתבים כל בקשה ליכולת המתאימה. ההרצאה מבוססת על מחקר שאורטל כתבה והתפרסם ב- arXiv 🔥 גיא ידבר על Hiring Post-Claude: מה הופך היום מפתחים למצוינים, למה ג'וניורים חשובים ואיך אנחנו ב-@Wix חושבים מחדש על גיוס ותוכניות פיתוח מקצועי. מגיעים ל- #Reversim - אל תפספסו את ההרצאות האלו!

איך חיזוי המילה הבאה הפך לבינה מלאכותית שיודעת לכתוב קוד ולהפעיל תוכנות? גלעד ברקן ראש גילדת הדאטה סיינס ב-Wix הנגיש את המאמר החדש שלו - From Autocomplete to Intelligence: How Language Became the Operating System of AI - למסמך פתוח בעברית, בשביל שכולם יוכלו ללמוד. המאמר של גלעד מסביר איך מודלי שפה לומדים, למה השפה נמצאת בלב מהפכת ה-AI, ואיפה היכולות שלהם עדיין מוגבלות. לא צריך ידע מוקדם, רק סקרנות. מוזמנים לקרוא, לשאול ולהשאיר הערות במסמך. docs.google.com/document/d/1…
