Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/2e6rhzjo **Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up ​​**Description:** ​IAI coding agents can now scaffold entire applications from a single prompt. But for mission-critical systems that require compliance, reliability, and auditability, "it works on my machine" isn't enough. When your agent makes fifty tool calls, rewrites three files, and confidently hallucinates a security vulnerability, how do you even begin to debug that? ​This talk introduces a practical, open-source toolkit for injecting observability, control, and systematic testing into agentic AI development. Using MLflow's tracing and evaluation framework, we'll follow a single throughline: building an AI agent with a coding assistant (Claude Code), tracing both the assistant's work **and** the agent it produces, then evaluating quality with LLM judges - closing the loop from development through production monitoring. ​You'll walk away with a concrete workflow for turning the black box of agentic coding into something you can inspect, measure, and trust. No vendor lock-in required. ​**Speaker Bio:** ​Tim Lortz is an AI Product Specialist at Databricks, where he has worked since 2019. He currently serves as the technical lead for Databricks' go-to-market efforts for AI in regulated industries, focusing particularly on enterprise-grade governance for AI platforms. ​ Prior to Databricks, Tim spent many years in various data science practitioner and leadership roles in the Federal contracting space.

Come volunteer with us refurbishing donated bicycles so that they can be used again by the community! This event is open to both new and existing volunteers. No mechanical experience is necessary. Note: The warehouse location is in the alley behind 1502 Mt Vernon Ave. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Please be aware that volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver, while volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

**IMPORTANT! Please register on [Luma page](https://luma.com/klm98cuc)** *Ignore the displayed time — it’s 5:30pm VA time.* AI is making us faster than ever — and at the same time, quietly questioning our place at work. ​We’re all feeling it: tools that boost output in minutes, automate entire workflows, and sometimes… do the job better. So where does that leave the human? ​This conversation dives straight into that tension — no sugarcoating, no generic optimism.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
