Good Project From Scratch

What to build?
What problem to solve?
"The root of all evil in programming is misunderstanding of the problem. Ask right questions to right people before first line of code." Mariusz Gil
"It's developers (mis)understanding not expert knowledge that get's released to production" Alberto Brandolini
"Tech people must speak the language of Business people, not vice versa." Stefan Priebsch
"The limits of my language mean the limits of my world." Ludwig Wittgenstein
Domain Driven Design
Event Storming
"The only thing that is constant is change." Heraclitus
Monolith vs Microservices
"you shouldn't start a new project with microservices" Martin Fowler
Service Oriented Architecture
Clean architecture
Don't reinvent the wheel
You're not unique
microservices serverless artificial intelligence machine learning blockchain nosql virtual/augmented reality internet of things cloud computing deep learning quantum computing
Test Driven Design
Tests !== Test Driven Design
"If it's hard to write a test, it's a signal that you have a design problem, not a testing problem" Kent Back
Continous integration
Continous deployment
Deployment !== Release (use feature toggles)
Business Metrics
If it moves, automate it!
"If boring repetitive things aren't automated a manager gets hired." Niranjan Paranjape
Start with README
Name of the service Point of contact and Slack channel Usage Running the service System Runbook Monitoring Documentation https://tech.buzzfeed.com/better-docs-8fccb8ebd6a4
"Documentation is a love letter that you write to your future self." Damian Conway
Communication is NOT a soft skill
Communication is a core skill!
"People who don't share their knowledge look more productive because they're holding back the entire team." Jessica Kerr
"I wish the understanding were more widespread that we plateau in coding skill mid-career, it is all about communication after that" Denton Gentry
Thank you!
Can you start a new project from scratch instead of maintaining legacy one? You're the lucky one! I want to talk how a good project should look like, from analysis phase till release and later maintenance. Talk will mostly about signaling important things to focus on like requirements analysis, code structure, code review, TDD, continuous integration, monitoring, performance tests etc. I don't want to go in-depth on every one of them but give you hints what is important and what to read more about and in which direction you should make research if you want to improve your skills, have a better project and be calm during next project release. During the talk I'll go through each phase of project lifetime and say what you as a developer should do on each of them to limit the possibility of ending up with legacy code.
