Join us for an evening packed with great people, strong tech content, and plenty of good vibes. Come curious, come hungry, and come ready to connect with fellow engineers from the local community. ## ​**​AGENDA (more updates coming soon):** ​​**​🍻🍉 17:30 - Gathering, Chats & Bites** ​​🎙️ **18:00 - ​Databases at the Crossroads of Scale, Real-Time, and AI** ​Z*ohar Elkayam Principal Solutions Architect, Aerospike* ​ Modern systems increasingly operate at the intersection of real-time data access, large-scale workloads, and AI-driven applications, yet architectures are still built on database choices designed for different requirements. This session explores the technical trade-offs that determine whether a database meets production demands. ​We’ll break down architectural dimensions that are often oversimplified: consistency models (eventual vs. strong and their latency impact), scalability approaches (vertical vs. horizontal, single vs. multi-region), data access patterns (key-value, document, graph), and durability and replication trade-offs (synchronous vs. asynchronous). We’ll look at how AI and ML inference pipelines increase pressure on tail latency, throughput predictability, and operational isolation. ​ Rather than advocating a specific technology, the talk presents a vendor-neutral framework for evaluating database architectures against real workload characteristics. Using real-world migration lessons, we’ll highlight common anti-patterns and show how better alignment between database design, access patterns, and SLAs can improve performance, resilience, and engineering efficiency.

Yet many teams struggle to trust the code these systems produce, especially in complex, distributed, enterprise environments. ​​In this talk, we explore why trust in AI-generated code is shaped as much by the execution environment as by the model itself. Drawing from real-world experience and the “three pillars of trust” for AI in software development, we argue that realistic, production-like environments are essential for both developers and AI agents to deliver high-quality results. ​​Attendees will learn how introducing ephemeral, fully representative environments into the GenAI development loop dramatically improves code correctness, system understanding, and deployment confidence, unlocking the full potential of AI-assisted development without sacrificing quality, reliability, or speed. **​** **18:40 - ​Stop Paying for Noise: Designing Lossless Log Reduction at the Source** *Gil Mazuz, CEO and Co-Founder, Aditty* ​​Log volumes are exploding, costs are unbounded, and sampling breaks trust. This talk explores how to reduce log volume by 80–95% without losing the ability to search for any trace, user, or error, by applying source-side, lossless design principles to production logging systems. ​​Log pipelines today optimize after the bill arrives. Sampling drops data irreversibly. Index caps hide failures. Engineers are left blind during incidents. ​​This talk reframes logs as a signal system rather than a raw data firehose, and explores how to design logging pipelines that preserve safety while controlling cost. ​ **LIGHTNING TALKS (20 MINUTES)** **​** **19:10 - ​DevOps Origin- The Anime Adventure (10 Minutes)** *​Sitar Gold, DevOps Engineer & Podcaster + Content Creator* ​ In this session, I’ll share my journey from IT engineer to DevOps, framed as an anime-inspired adventure. Just like in the best anime series, landing my DevOps job marked the end of one chapter and the beginning of the real journey. Through practical experience, mentorship, and overcoming misconceptions, I’ll highlight the key lessons that shaped my path and how others can level up in DevOps. Whether you're a junior or senior, this talk offers insights into making the switch and growing in the field. ​​ **19:20 - Take Back Control of Your Observability Cost** *Yogev Krieger, Founding Engineer, Sawmills* ​​Most teams treat Datadog as a black box that steadily consumes more budget, but AI tools now let you proactively audit and optimize your observability spend. This session demonstrates how to use AI agents to enforce observability hygiene, identify waste, and ensure teams use your telemetry platforms efficiently. You'll walk away with practical strategies to maintain control over costs and data quality as your infrastructure scales. ​​ **19:30** - **BONUS IGNITE: Open Source in Israel - Next Insurance introduces [Tagemon](https://github.com/next-insurance/tagemon)** ​*Amit Shlomovits, Senior DevOps Engineer, Next Insurance* ​​ **​🥳 19:30 - More Community Mingling and Fun** \*\*\*\*\*[pls note registration for this event is HERE](https://luma.com/q1-26-tlvcommunity-blitz)\*\*\*\*\*

**To confirm your spot, please complete your registration on our official Luma event page:** **[https://tkl.to/tikal-s-meetup-25-2-26](https://tkl.to/tikal-s-meetup-25-2-26)** **You’ll receive a confirmation email once your seat is approved.** **When**: Wednesday, February 25, 2026 18:00–20:00 **Where**: Tikal offices, 6 Kremenetski St , 1st Floor, Tel Aviv \*The meetup will be held in Hebrew In many development teams, AI adoption still starts and ends with a prompt window. Useful, but limited. The real shift begins when teams move from isolated prompt experiments to agentic workflows that actually support delivery. How do personal AI habits turn into something a team can rely on. What tools and working patterns are emerging. And what does an Agentic SDLC look like once it goes beyond one developer. This meetup explores the evolution of developer workflows in the age of AI. From personal IDE setups and smart context reuse to the early foundations of Agentic SDLC at the team level. The event is inspired by Tikal’s Tech Radar Voice podcast series “Agentic SDLC: From personal workflow to team workflow” and brings those conversations into a live, interactive setting. **On the Agenda:** **18:00–18:30** Welcome drinks and networking **18:30–19:15** From Manifesto to Main Branch: A Spec Driven Approach to the Agentic SDLC// Lior Kanfi, CEO & Founder, Tikal AI coding agents promise velocity, but often deliver chaos. The root cause is usually the lack of a shared source of truth. Instead, teams end up with inconsistent vibe coding, where ad hoc prompts lead to unpredictable results. In this talk, Lior shows how to ground the Twelve Factor Agentic SDLC in the principles of Spec Driven Development. He will introduce the agentic sdlc spec kit, an open source toolkit that makes this approach practical. You will see how a single /specify command can translate a business requirement from an issue tracker into a formal, version controlled specification. This spec.md becomes the contract that governs the entire AI workflow, from automated planning and implementation to generating risk based tests. The session focuses on how teams can move from unpredictable prompting to a governed, spec driven system that turns AI from a clever gadget into a reliable and accountable team member. **19:15–20:00** Panel discussion: Working with AI: from personal routines to teamwide Agentic SDLC Moderator// Nir Kaufman, Tech Lead, Tikal Panelists * Oren Melamed, AD of R& D and GenAI Adoption Lead, AT& T * Muly Gottlieb, Head of Engineering, Applitools * Roy Kass, Fullstack Tech Lead, Tikal ​In the panel, we’ll hear from the speakers about: * ​How they’re personally using AI tools in their own day-to-day work as developers, leads, and product people * ​What their teams are trying when it comes to integrating agents into real workflows and where things still get stuck * How dev environments are evolving: IDE setups, context management, and async flows * ​What Agentic SDLC actually looks like when it starts to take shape across a team * ​Lessons, surprises, and small changes that made a big difference in how they work **From the podcast series** State of Agentic SDLC [https://tkl.to/tikal-spotify-state-of-agentic-sdlc](https://tkl.to/tikal-spotify-state-of-agentic-sdlc) Personal Workflow and Spec Driven Development [https://tkl.to/tikal-spotifiy-personal-workflow](https://tkl.to/tikal-spotifiy-personal-workflow) Context Engineering [https://tkl.to/tikal-spotify-context-engineering](https://tkl.to/tikal-spotify-context-engineering) Agentic SDLC for a team Coming soon

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
