Crafting a Clean, Pragmatic Architecture

Part 1: Crafting a Clean, Pragmatic Architecture

Let’s have a critical review of the major decisions taken in a typical enterprise application architecture and learn to balance pragmatism with design goals. Find out how to do just-in-time design to keep as many use-cases as simple as possible (KISS).

We’ve all seen that without continuous refactoring simplistic design eventually degenerates into a Big Ball of Mud, under the assault of new features and bug fixes. At the other end, over-engineered code can burden the start-up of the development and then end up freezing the code in some rigid ‘a-priori’ design. It’s up to us to strike a balance that will preserve Developer Happiness™. To do that, we should regularly challenge the architecture of our system and seek ways to simplify it to fit our present needs, with a pragmatic mindset.

“Architecture is the art of postponing decisions”, said Uncle Bob. This session takes this idea further and explains how to Evolve a Pragmatic, Clean Architecture (aka Onion), guiding the design by what Genetic Programming would call a fitness function. It’s the philosophy Victor applied to design and develop 9 applications for IBM, and a key topic of the trainings he delivered at dozens of companies.

Along the way, you’ll also get a nice review of the fundamental data structure types, how to keep the logic simple by two types of extractions, enforcing boundaries using dependency directions, and crafting a testable design, all in a fun, dynamic and interactive session.

Part 2: Live Coding
There will be a short and entertaining live coding session after the talk. You do not want to miss it and the best part is - you get to decide what it is going to be! Options will be given for you to choose from.

Agenda:

>>> 20:00 – 20:30 Live Coding (you don't want to miss it!)
>>> 20:30 – ??:?? Networking (Drinks & Food)

About Victor:
Victor Rentea is a Java Champion and one of the top Independent Trainers in Romania, having trained by now 1200+ developers in 30+ companies. He is Lead Architect at IBM, where he practices Pair Programming, Clean Code and Refactoring every day. For the community, he organized the largest 3 Bucharest Java User Group meetups in history, and last year he founded the Bucharest Software Craftsmanship Community in which he runs free webinars about clean code, refactoring and TDD.

As a speaker, Victor is regularly invited at the top international conferences: his live-coding sessions are insane, lightning-fast but well crafted, full of enthusiasm, deep insights and take-away tips. Bulgarian audience may remember him from JPrime 2017 in Sofia. To learn more about/from him, follow his daily thoughts on social media, or check out http://victorrentea.ro
