A developer writes a prompt, reviews the output, finds bugs or architectural issues, rewrites the prompt, and repeats, generating wasted iterations and unused code along the way. ​We built a different loop: AI that checks itself end-to-end. ​In this talk, we’ll show how our agent starts with fast static feedback using ESLint and TypeScript, validating its code instantly. It runs unit, integration, API, and third-party contract tests, executes real user flows via Playwright MCP, inspects logs during development with Sentry SpotlightJS, commits and pushes to GitHub, and deploys through Vercel, and solves CI issues. ​Finally, we’ll show how, using Ralph Loop — built on a Research → Plan → Execute → Review framework — the agent can iterate overnight and continuously develop. ​You’ll leave with a practical blueprint for building fully agentic, self-correcting Node.js workflows. *** ​ **Rules Are Dead. Here's What's Next for AI-First Teams.** ​by **Or Rozenzweig, Backend Team Lead , [Wix.com](https://wix.com/)** ​My AI can read every file in my repo. But it doesn't know why my service exists, what my PM wants, or which patterns my team agreed on over lunch six months ago. ​That context — the stuff that lives in Slack threads, in people's heads, in tribal knowledge — that's what makes the difference between a nice autocomplete and code that actually ships. ​Over the past few months, my team has been closing that gap. Not with bigger models or better prompts — with structure. ​In this talk I'll share what's working for me and my team: [AGENTS.md](https://agents.md/) for project context, Skills for reusable workflows, and CDD — a way to get your whole team (PM, dev, QA) collaborating through AI agents. ​Live demos, real code, things you can start using Sunday morning. *** ​**DX Guardrails for AI** ​**by Kiril Reznik\, Software Engineer\, Aternus \| Master Builder** ​Get shivers down your spine when you see a PR with 1k+ lines of code changed? ​With Agentic dev workflows it's easier than ever to get yourself burned out in code reviews. ​Sure we could just "ship fast and break stuff", perhaps ask the agent to implement a feature flag, but who's going to operate it when production breaks and an angry customer call wakes you up in the middle of the night? ​Join me to learn about the guardrails that keep code reviews scalable and DX great. ​Together we'll explore how SDLC has evolved over the past 2 years and you'll leave with practical tools to keep your sanity and reduce risk of surprises while working with AI. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ​ Kindly be informed that attendance at the meetup is on a first-come, first-served basis until capacity is reached.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
