DevOps for JavaScript Developers: From Code to Production

Workshop

This workshop closes the old and very real gap between Node.js developers and production.Many Node.js developers can build APIs, services, and backends that work locally—but things fall apart when it’s time to containerize, deploy, scale, and operate them in real environments. This workshop fixes that.This is where Node.js stops being “just code” and becomes a reliable production system.What you’ll learn:Dockerize Node.js applications for development and production using battle-tested patternsDesign clean, fast, and secure Docker images for Node.jsBuild scalable CI/CD pipelines with GitHub ActionsOptimize Node.js apps for performance, stability, and observability

DevOps for Front-end Developers: From Local Code to Production by Docker Captain

WorkshopPro

Many front-end developers build modern applications with confidence, but struggle when it comes to shipping those applications to production. Docker, CI/CD, environment configuration, performance tuning, and deployment often remain “someone else’s job” — until something breaks and becomes your responsibility. This workshop closes that gap.
It’s a practical, production-focused workshop designed for front-end developers who want to take full ownership of their front-end applications — from local development to stable, production-ready deployments.

You’ll learn how to:
- Dockerize front-end applications for both development and production- Create optimized, production-ready Docker images for modern front-end frameworks- Optimize front-end applications for performance, stability, and reliability- Avoid common production mistakes seen in real-world front-end projects

Training Engineers for AI Without Turning Them into Prompt Monkeys

TechLead Conf Amsterdam 2026: Adopting AI in Orgs Edition

Upcoming

Training Engineers for AI Without Turning Them into Prompt Monkeys

AI is reshaping how engineers work, but many organizations are training teams in the wrong direction—optimizing for prompts instead of thinking. This leads to fast output, shallow understanding, and fragile systems. This talk focuses on how tech leaders and senior engineers can adopt AI while preserving engineering judgment, ownership, and long-term system quality. You’ll learn how to train engineers to use AI as a tool—not a crutch—without sacrificing craft or increasing complexity.
