Serokell at ZHF Hackathon

Last Friday, some of Serokellers participated in a semi-physical [Zero Hydra Failure Hackathon](https://nixhax.github.io/zhf-21.11/index.en.html) in [undefspace](https://undef.club/#about), Moscow.

Together with other attendants, we managed to push more 6 PRs in less than 8 hours and fix a lot more packages (due to a fix of  `openjfx` by our site reliability engineer Alexander Bantyev).

About a week ago, we participated in ZuriHac, the biggest Haskell Hackathon in the world, and want to tell you how it was.

About a week ago, we participated in [ZuriHac](https://zfoh.ch/zurihac2019/), the biggest [Haskell](https://www.haskell.org/) Hackathon in the world. During the event, we visited several talks, the most popular among which were those about GHC, and organized a Morley workshop together with the Tocqueville Group.

The participants of our workshop could use a special [web page](https://morley-zurihac.serokell.io/) to learn about Michelson and Morley as well as check the issues prepared for them. On Saturday and Sunday, all comers had a chance to discuss Michelson, ask questions, read tutorials, set up their working environments and try to solve our issues.

One of the participants, [Sébastien](https://besnier.se/), successfully implemented an [optimizer](https://hackage.haskell.org/package/morley-0.5.0/docs/Michelson-Optimizer.html). He presented his work during the project demos, and it was really impressive. It worked as expected on artificial examples, and it also optimized our DS protocol contract. After ZuriHac, we modified Sébastien’s work a bit and made a [merge request](https://gitlab.com/morley-framework/morley/merge_requests/2), which we’re going to review soon.

Many thanks to all the ZuriHac participants! We love the Haskell community and hope to see you all soon again.

TopDevelopers Interview Serokell CEO Arseniy Seroka

Learn more about Serokell and our recent initiatives by reading this interview from TopDevelopers.co.

> I think that our primary advantage is how we build our team. In the beginning, many of our engineers were friends that we had known for years, and we trusted them. As the company grew, we hired a lot of new people from different continents, but we still maintain this almost family-like relationship inside the company.

Our CEO Arseniy Seroka was recently interviewed by TopDevelopers, a B2B research and rating company that is focused on connecting firms with top IT firms and custom service providers. 

In the interview, Arseniy talks about the founding of Serokell, what he perceives to be the biggest strengths of the company, and some of Serokell's recent initiatives, including Serokell Labs and Serokell Academy. 

The interview also includes his opinion on some of the software development fields like AR/VR, IoT, and mobile. 

You can read the full interview on the [TopDevelopers website](https://www.topdevelopers.co/profile/serokell/191/interview-Arseniy-Seroka).
