MoCo Code & Coffee May (@ EOB Cafeteria)
MoCo Code and Coffee is an inclusive, informal, co-working session. We're community-led and community-run by devs, for devs. People of all skill levels are invited. Especially new devs!
Bring a laptop, ideas, and we'll provide the coffee and snacks.
**Here's how it works**
At 2:30pm, everyone introduces themselves and briefly mention what brought them to Code & Coffee today (project, homework, networking, etc.)
Round 1:
1. Your name
2. What you're working on
3. What you can help others with
Round 2:
* Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool.
Round 3:
* Community events you wanna plug. If none, that's cool too.
**After the introduction circle, everything is self-organized!**
1. For the rest of the day, folks work on their projects, providing one another with help, and/or socialize. It's fully up to you.

Open Bar & Seminar (Free but RSVP required)
After hosting successful events, I always think that we could have done better and relate it to our day to day life and make it educational. In this connection, I wanted to show off my investment and trade hat and organize series of Happy Hours around Investment & Trade.
We will have speakers from different sectors and industries, at each Happy Hour. At this particular event, the speakers will discuss Retirement Saving (With An Overview of Interest Rate & Housing Market).
Topics will include:
• Today’s retirement savings challenges and approaches
• Sources of income in retirement
• Proper investment strategies
• Current interest rate environment and what to expect going forward
• State of the housing market
The address will be sent to members, who RSVPed, before the Event.
Enjoy!
Spec-Driven Development with GitHub Spec-Kit - Barret Blake
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.
