DC Code and Coffee is an inclusive, informal co-working session. It's community-led and community-run by devs, for devs. People of all skill levels attend. Whether you’re dev-curious, aspiring, or a professional developer, we’d love to have you! Come chat or learn to code on a Sunday afternoon with coffee and cool-inclusive people. Bring your laptop! We typically meet every month on the weekend. **Join our online community!** For all things Tech in DC and to get latest updates and tech events from the DMV area, join the [DCTech Slack](https://dctech.chat/). All DC Code & Coffee announcements are in the #dccodecoffee channel **How it works** Near the beginning of the event, we do an introduction circle. You say your name, what you can help others with, and what you would like help with. You can also share job opportunities. After the introduction circle, everything is self-organized.

Cozy Wine Therapy events are back. This is my kind of therapy session. In the comfort of my living room (or a volunteer), we will unwind and share our personal highlights and lowlights since we last met, and with the help of friends (and wine) we will "release" any negativity we may be holding onto as well. We will be here to listen and share advice if that is what's needed. Sometimes just having someone to listen is all we need to feel better. Be prepared to share! No couch surfers allowed. :-) My living room is a safe non-judgmental space. What is shared will not be discussed beyond my living room unless you decide to share. Feel free to bring a bottle of wine to supplement the stock, or a snack, if you wish. NOTE: My apartment is NOT good for those with cat allergies. I am conveniently located a mile from Huntington Metro Station off of Huntington Ave. with plenty free parking. To be invited into my home, I will have had to meet you at an event prior. Makes sense, right? I will message the group my address a few days before. Make sure your notifications are ON.

Join us for an evening of deep product insights and conversation with Steve Johnson, CEO of Product Growth Leaders. Most product managers aren’t struggling because they lack frameworks, data, or AI tools. They’re struggling because they’re talking to the wrong people. Instead of learning directly from customers, they rely on second-hand input—sales requests, executive opinions, support tickets, dashboards, and now AI-generated summaries of all of it. The result? Noise. Misalignment. And products that look good on paper but miss the market. AI can process more data than you ever will—but it can’t replace direct human understanding. It can’t see hesitation. It can’t hear what’s not being said. And it certainly can’t build trust with a customer who doesn’t believe you yet. That’s where product managers have an advantage—if they choose to use it. In this session, you’ll learn how Customer Conversations cut through the noise and become your most powerful differentiator. Not as a research technique, but as a leadership behavior that builds market insight, credibility, and better decisions. Through real stories and practical methods, you’ll learn how to: • Talk to the right people at the right time in the product lifecycle • Ask questions that uncover real problems • Validate ideas before you build them Because in a world where AI can generate answers at scale, the product manager who understands customers firsthand becomes the one who asks better questions—and makes better decisions. AGENDA 6:00 - 6:30 pm: Welcome and Registration. Refreshments provided. 6:30 - 7:00 pm: Talk by Steve Johnson (CEO at Product Growth Leaders) 7:00 - 7:15 pm: Q&A 7:15 - 8:00 pm: Networking ABOUT THE SPEAKER Steve Johnson is a product success coach focused on removing the chaos from product planning. He uses modern methods to guide product teams from idea to market in only a few weeks. Steve has trained tens of thousands of product professionals in his career. He is a former instructor and vice president at Pragmatic Institute and the chief architect of the popular Quartz Open Framework.
