**8 Hours in a Dev’s Shoes: Cold Coffee, Red Pipelines**
by Zdeněk Heller

A day in the life of a microservices dev. Zdeněk Heller shares what slows him down, what works, what meetings actually solve (or don’t), and what really helps him stay focused on coding.
What you’ll learn:
• What a dev’s day really looks like
• How automation and DevOps culture change the game (for better or worse)
• Where DevOps empowers developers vs. where it just adds overhead• Real examples of blockers vs. boosters for developers
• How good (or bad) collaboration between dev and ops impacts daily work

Find out how to give developers back control so they can focus on what they do best: coding? Whether you’re in ops or dev, this session will help you see how your decisions affect the whole team.

**NATS**
**by Vaclav Broz**

Messaging is essential: for decoupling services, real-time UI updates, and syncing things like cache invalidation. We explored the usual suspects. **Kafka** was overkill. **Firebase** locked us in. **Redis Pub/Sub** lacked reliability. **WebSockets** were too bare. **RabbitMQ** was too complex to scale and fragile under load. We chose **NATS** for its simplicity, speed, and flexibility. This talk is about **why** and what it took to get it running in production. We’ll share the integration challenges, real-world lessons, and what to watch out for if you're considering NATS.
