### Enabling Code & Processes Quality - A unique journey
> Ask yourself, how many times in your professional career will you have the opportunity
to be involved in the inception of a technology hub? No legacy code or processes, just
this unique opportunity for data driven innovation and collaboration?

### Guidelines
* Follow Open Source best practices<!-- .element: class="fragment" data-fragment-index="1" -->
* Be Agile & have a DevOps oriented process<!-- .element: class="fragment" data-fragment-index="2" -->
* Have scalable code ready for Big Data<!-- .element: class="fragment" data-fragment-index="3" -->
--
### Best practices
* Code reviews
* CI/CD
* Automated testing
--
### Agile & DevOps oriented process
* Be able to compromise on technology and programming language<!-- .element: class="fragment" data-fragment-index="1" -->
* Replace unnecessary meetings with collaborative messaging tools<!-- .element: class="fragment" data-fragment-index="2" -->
* Finding the right DevOps topology<!-- .element: class="fragment" data-fragment-index="3" -->
--
### Scalable code and infra
* Use scalable engines (Spark, Kafka, Flink, ...)
* Use scalable infrastructure and databases

### Choosing the Tech Stack
> There is no one single tool/technology/process for all situations
--
### So... Be Agile and improve!
<img data-src="./img/agile.gif"/>
--
### Methodologies
* Scrum/Kanban/Scrumban
* Demos/Retros
* OKRs (Objectives and key results)
--
### Programming languages
* Java and Scala
* Python and Jupyter Notebooks
* Terraform and Ansible
--
### Ecosystem
* Confluence and JIRA
* Azure as IaaS
* JFrog Artifactory
* GitHub and Drone CI

## Principles
> While technologies come and go, principles and good practices should be constant
--
### Software architecture principles
* Build in small increments<!-- .element: class="fragment" data-fragment-index="1" -->
* Change should not be expensive<!-- .element: class="fragment" data-fragment-index="2" -->
* Do not use speculation to add extra complexity to the architecture<!-- .element: class="fragment" data-fragment-index="3" -->
* Stop to think what are the bottlenecks (what can go wrong)<!-- .element: class="fragment" data-fragment-index="4" -->
--
### Testing
> If your code does not have automated tests, it’s broken. You just don’t know it yet...
* Unit tests
* Integration tests
* Smoke tests (aka Sanity checks)
* Acceptance tests
--
### Testing
<img data-src="./img/tests_time.png"/>
--
### Static code analysis
* Finds bugs and vulnerabilities early
* Consistency
* You can define your project specific rules
--
### DevOps/SRE (Site Reliability Engineering)
* Install, Configure, Provision, Deploy, Secure, Monitor, Log, Backup...
* High availability, scalability, performance, network, cost optimization, ...
* Documentation, testing and maintenance

### Enforce quality
* Add automated quality checks
* Have fortnightly feedback loops on demos and retrospectives
* Only recruit great people and maintain high retention rate

### At last... Some personal tips
* Learn by actually reading source code in Inner and Open Source reference projects<!-- .element: class="fragment" data-fragment-index="1" -->
* Read, attend meet-ups/events and contribute on Open Source projects<!-- .element: class="fragment" data-fragment-index="2" -->
* Go extra mile on automation<!-- .element: class="fragment" data-fragment-index="3" -->
