About us

Technical Excellence is the foundation of sustainable software engineering. Without technical excellence, there's no quality; the development is slow and cannot be sustainable. Without technical excellence, there's no agility.

Do you want to share knowledge about software quality, to build better products?

This group is for engineering leaders and software developers who are motivated by building high-quality solutions and continuously improving. Technical Excellence is both a mindset and a set of practices to help us build quality software faster and deliver value sooner.

Our focus will be on the following topics:

  • Extreme Programming
  • Software Craftsmanship
  • Continuous Integration
  • Continuous Delivery
  • Trunk Based Development
  • Test Driven Development
  • Hexagonal Architecture
  • Clean Architecture
  • Domain Driven Design
  • Use Case Driven Design
  • System Design
  • Clean Code
  • Refactoring
  • Technical Leadership
  • Learning Culture

Our sessions will be in English, held remotely, and open to participants across the globe.

Our goal is to share knowledge, discuss diverse perspectives and synthesize our collective knowledge.

    Your team automated testing.

    So why does every release still wait for QA?

    You invested in E2E test automation to get faster releases and fewer bugs.
    Instead, what you got is a test suite that breaks with every UI change, a team that doesn't trust it, and a manual regression pass that still sits between "done" and "released."

    Now AI is helping your developers write code faster, and the queue in front of QA is only getting longer.

    This isn't a people problem, and more automation of the same kind won't fix it. It comes down to how the tests are designed.

    In this webinar, you'll see:

    → Why E2E automation rarely replaces manual QA — and the three design decisions behind it

    → What changes when tests are written in business language — your product owner can read them, QA can trust them, and UI changes stop breaking them

    → How to start small with one critical use case, without stopping delivery or rewriting everything

    → How to get it funded by presenting the business case in terms of release speed, cost of bugs, and time spent on repeat work

    You're an engineering leader who wants to make an impact.

    This is for you if:
    → You lead an engineering team (as engineering manager, head of engineering, or CTO)
    → Releases are slowed down by manual testing
    → Your team tried test automation and it didn't deliver what was promised

    Valentina Jemuović is a technical coach and the founder of Optivem. She coaches engineering teams in ATDD and TDD, helping them deliver software faster with fewer bugs. She works in Java, .NET and TypeScript, and shares her work with ~30K followers on LinkedIn.
