Embedded Systems

The playbook for AI agent integration is becoming predictable: build an MCP server, expose your APIs as tools, and define the rules in prompts. That approach works, but it often pushes workflow and guardrails into client-side logic, where they are harder to enforce and easier to bypass. This talk presents a different approach. HATEOAS (Hypermedia As The Engine Of Application State)—a largely overlooked part of REST—allows an API to describe allowed actions and constraints at runtime. That makes it a natural fit for agents, which need clear, machine-readable guidance about what they can safely do next. We’ll show this in action with MoneyMate, an AI agent that performs sensitive operations such as money transfers. Using the Spring HATEOAS project, the agent is guided entirely by the API rather than by hardcoded tools or fragile prompt logic. AI hype aside, this is ultimately a talk about architectural validation. For years, HATEOAS was the hill REST purists loved to die on—complete with finger-wagging about “doing REST correctly”—while everyone else quietly shipped simple JSON and moved on. It turns out the purists weren’t wrong—just 20 years early. Come see why that extra structure finally pays off when your client is an LLM. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu.

## Rehearsal Details: Thursday evenings 6:30 p.m. to 9:00 p.m, Earl Bales Community Centre 4169 Bathurst St., just south of Sheppard, in Toronto. Email our membership chair, if you are interested in attending a rehearsal. **Lisa Taylor: 647-886-1766, [membershipchair@torontoaccolades.com](mailto:membershipchair@torontoaccolades.com)** Do you love to sing? Do you love performing for live audiences? The Toronto Accolades Chorus brings women-centric singers together to sing and perform a cappella harmony. Harmony connects people from all backgrounds, ages, and musical abilities to create a community where you can not only sing, but find a space to connect with other strong and dedicated people just like you. For decades, we've provided a venue for singers to express themselves, make quality music together, and form bonds beyond measure, and we invite you to join us for the ride. We welcome guests and work with them to find out their voice range and to determine what part (lead, tenor, baritone or bass) they would sing best. Guests are given a music folder and encouraged to participate in singing with the chorus in subsequent weeks. Although we continually strive for musical excellence, prior musical training is not necessary to belong to our chorus. We provide everyone with sheet music, audio learning tracks, education and guidance. At the end of 6 weeks, we ask each prospective member to audition, to ensure that they can hold their part in a four-part harmony song.

**This is a ticketed event.

**Agentic SDLC** Software delivery is entering its next phase—one where the SDLC doesn’t just execute, it collaborates. Agentic SDLC brings AI out of the sidelines and embeds it across every phase of the lifecycle—from planning and coding to testing, deployment, and operations. These aren’t passive tools waiting for prompts—they’re proactive teammates that anticipate needs, automate repetitive work, surface risks early, and keep delivery flowing. In this session, we’ll explore how intelligent agents are reshaping the entire SDLC. Think beyond code completion: agents that refine backlog items, generate and review pull requests, create meaningful tests, enforce standards, flag risks before they become incidents, and even monitor production with context. We’ll walk through real-world scenarios and practical implementations showing how teams are using agentic approaches to boost productivity, improve code quality, and accelerate delivery—without sacrificing control or flexibility. You’ll also see how this can be done across a diverse ecosystem of tools and platforms—cloud or on-prem, open-source or commercial—so you can adopt what works best for your environment. Whether you’re a developer, tester, architect, or team lead, you’ll leave with concrete patterns and ideas to evolve your SDLC into a smarter, more adaptive system—where AI doesn’t replace the team, but makes every part of it stronger. **Speaker: Max Yermakhanov** *DevOps guy, Automagically* A passionate and forward-thinking DevOps guy, Max brings over 20+ years of experience helping organizations modernize how they build and deliver software.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.
