Tech Evangelist for Datadog
It might seem like Datadog is a young pup born into microservices. However, like many organizations we started with larger code bases and VMs. Scaling the company while building a system that handles trillions of data points every day required a shift in how we work and the tools we use.
In this session, I’ll share tips for how to break apart your monoliths and large code bases into faster, loosely-coupled services. I’ll give advice for managing your services and troubleshooting issues in a microservice environment. And more importantly, I’ll share strategies for getting buy-in and alignment across your organization.

Staff Engineer for TYPO3
PHP’s latest major release is a truly major release! (And tautologies are tautologies.) With more ease-of-use functionality than you can shake a stick at, PHP 8.0 promises to offer more power in less code than any PHP version to date.
Covering the whole of PHP 8.0’s improvements would take a whole book (and has), but we can cover the major features in an hour. Expect code that is easier to write, easier to read, and more flexible than ever before in the web’s premiere server-side language.
If after this talk you aren’t itching to move your code to PHP 8.0, you’re either asleep or not a PHP developer (so why are you here?)

Senior Backend Engineer at Clevertech
Java was a quite popular programming language that is becoming less and less popular because of modern programming languages that offer benefits like avoid compiling the code which increase the development speed by a lot in large projects, cheaper platforms to deploy applications, reduced learning curve, simpler architecture models and a bigger ecosystem that developers can take advantage of to develop new products.
No doubt that JavaScript in conjunction with Node JS is one of the strongest options in this field, in this talk, I am going to show how to move from a Java/JEE ecosystem to Node JS and how to make this transition smooth. I will share all the experience during my journey of 10+ years of experience as Java developer/lead/architect to become a successful JavaScript backend expert.

Eclectic Code Designer
This talk describes the challenges of developing UIs that are integrated with complex external APIs. Using tools such as React Styleguidist or Storybook eliminate the need for an integration, enabling us to develop components in isolation, outside our application. This technique enables us more flexibility during development and debugging, while also providing a living documentation for our UI components.

Software Developer at Hazelcast
When your application starts slowing down, the reason is probably a bottleneck somewhere in the execution chain. Sometimes, this bottleneck is due to a bug. Sometimes, somebody didn’t set up the optimal configuration. And sometimes, the process of fetching the data is the bottleneck.One option would be to change your whole architecture. Before moving to such a drastic, and probably expensive measure, one can consider a trade-off: instead of getting remote data every time, you can store the data locally after the first read. This talk focuses on options available regarding those interactions.

Senior Developer Relations Engineer at Google
Time series forecasting is a powerful way to use current or historical data to monitor, clarify, and predict “cause and effect” behaviors which can better inform future decisions. Anomaly detection for a time series can detect critical incidents such as fraudulent behaviors or potential opportunities such as changes in consumer buying patterns. Join this talk, to see the newest features in BigQuery ML in action and simplify your workflow in time forecasting and anomaly detection.

Advocasy at Gremlininc
As software systems become more distributed and complex, failure is inevitable. But catastrophic bugs and system outages can be excellent learning opportunities to build more resilient applications. This session will provide methods and techniques for gathering information and effectively using that information to avoid and mitigate failure in the future.
I’ll cover best practices for gathering systems-related data, including monitoring and logging. This session will also cover practices for gathering and recording people-related data; including methods we can adopt from police, accident investigators, and other safety management professions to learn the most from incidents.
After discussing how to gather data, I’ll discuss how we can use the data to formulate actionable response plan, how to validate your plan with Chaos Engineering, and how to adjust existing organizational practices to avoid repeating failure.
