KEtchUp #5

KEtchUp is back!

How we fixed it: challenges we faced and overcame 

Join our fun tech meetup evening, where you will listen to 3 inspirational speakers from Microsoft and Kiwi.com.
This time about all the times we had to switch focus, develop a new solution… and ensure the outcome would be great! 
Apart from the three speakers, you can look forward to a small refreshment and the possibility to network with fellow attendees – as always :) 

1. Daniel Janočko @kiwi.com: UX Under Business Pressure: Why WebView Beat Native

When technical decisions collide with business requirements, the winner is often not who you’d expect. In our case, we sacrificed native development in favor of speed and flexibility with WebView—and to our surprise, our users didn’t seem to mind. In this talk, I’ll share the challenges and trade-offs we faced during this transition and how we navigated the compromises in user experience that came with it.

2. Dmitry Osipov @microsoft: Building Reliable Systems From Unreliable Parts

Service-oriented architecture is a great architectural style, but it comes at a price. The more (micro)services you have, the more remote requests you'll have to send across them to have a working system. The more requests you make, the more failures you get. But don't panic yet! Even though you can't avoid failed requests, you can deal with them.

In this talk we'll explore resiliency patterns that can improve Quality of Service and latency, and make customers happy.

We'll cover some basic strategies such as Timeout, Retry, Fallback, and also more advanced ones such as Hedging, Circuit Breaker, Rate Limiting. We'll discuss how to combine mentioned strategies and will learn on examples why mindfully configuring your resiliency strategies is as important as having them.

3. Michal Cyprian @kiwi.com: Deliver, Deploy, Refactor, Repeat! 

"Can we deliver a reasonable MVP scope of this strategic airline partnership integration in three weeks?" asked the Senior Design Manager during a late Friday afternoon ad-hoc meeting. "Impossible," I responded. "Three weeks are not enough, not even to adjust UI communication significantly." To my surprise, I was proven wrong!

In this session, we take you behind the scenes of delivering a production-ready MVP under extreme time constraints. Using a real-world case study of a strategic airline partnership, we’ll reveal the critical factors for success in rapid delivery and demonstrate various refactoring approaches to deal with the subsequent technical debt — Full Rewrite, Modular Refactoring, and Incremental Improvement. Discover how "Deliver, Deploy, Refactor, Repeat" became our winning strategy.
