It’s been couple weeks since our last event, so here’s the follow-up:

Last devclub was hosted in Transferwise new office in Baltika district. It is located almost exactly where their previous office was, right the opposite building. Transferwise is really great host, made this event special and guests feel very welcome. We’d love to come again to them with Devclub the other time.

This time we had four speakers and three talks. First one was by Erko Risthein from Transferwise. The talk was more financial than technical. It was about currency rate change risk management and how to perform money transactions with different currencies and not loose money when currency exchange rate is changed. The idea is quite simple, yet really smart. Each time you sell some amount in one currency you buy equivalent value in other currency and vice versa. This ables you to lock the exchange rate between these two currencies at certain state that existed at the moment when transaction started. It is called currency hedging. Erko did great job explaining this concept in his talk, I’m really glad I had a chance to hear and see him. Now I have good understanding on the subject.

Second talk was also by Transferwise engineers Dmitry Zhukov and Maksims Juvcenko. Their talk was about how they built a fraud detection engine. It was a story about how the project evolved and how the guys helped it to get better. How to get started when everything needs to be fixed and everything is important. How to make decisions and prioritize in though circumstances.

Can’t really say much about the last talk as I did it myself. Probably it was epic 🙂 I was talking about AWS Lambda – what it is, how we use it for our needs in Folkefinans and how you might want to use it.

There was an office tour after the talks too, had to skip this one so can’t really say much about the office. From what I managed to see it looked really nice, definitely a place you want to be in.

Unfortunately there’s no pics from the event this time, but at least we managed to record the videos of the talks (here, here and here), so there’s a great way for you to follow-up if you missed it. This is pretty much about it. Thank you and see you at the next Devclub really soon!
