Clean Architecture and Domain Driven Development for the 2023 Nebraska Code Conference

I have the great privilege of presenting at the 2023 Nebraska Code Conference on July 21, 2023 at 2:30 pm.

If you see this at the conference, it’d be cool if you said hi and left a comment or feedback on my my tweet .

Main Goals - OKRs for my presentation

I decided to attempt some OKRs for this presentation. More about OKRs

Objective

Attendees will consider the importance of architecture on the success of a product over time and be introduced to Domain Driven Design.

Key Results

• Key: Attendees thinking about architecture
  • Result: A feedback comment or comments will mention architecture challenges they’ve faced
• Key: Share we’ve learned from reading Clean Architecture by Uncle Bob Martin in an Omnitech book club .
  • Result: A feedback comment that they plan on reading one or both of the books
• Key: Introduce Domain Driven Design (DDD) and new things I’ve learned in 2022 at Omnitech through a series of lunches using Pluralsight and through Scott Wlaschin’s Domain Modeling Made Functional book.
  • Result: A feedback comment they they want to learn more about DDD.
  • Result: A feedback comment they they want to learn more about applying functional concepts and read the book.
• Key: Enabling common terminology for discussions about architecture and DDD with their teams.

My PowerPoint Presentation

This is an updated version of the 2019 SD Code Camp Presentation I gave with John Townsend .

Recommended resources on Functional DDD from Scott Wlaschin

His talk at NDC 2019 on DDD

His conversation on the Azure DevOps Podcast

• apply functional thinking to architecture - min 20:53
• immutable
• easier to test
• db code on the outside - onion architecture
• pipelines

This is what kicked my interest in Functional Architecture

Gene Kim interviewed Scott Haven . This was eye opening and got me thinking about Functional programming and how it could be applied to architecture. I also go to use some F# at work.

Here Scott Haven presents about using this for Jet, now Walmart DOES 2019 - Forging a Functional Enterprise - Fabulous Fortunes, Fewer Failures, and Faster Fixes from Functional Fundamentals .
