Senior Software Engineer at Google, Non-Executive Director at WebbyLab

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Everyone writes backend tests, but little attention is often paid to frontend tests. And really, is it worth writing tests for the frontend? What difficulties will you get? And what about snapshot tests? What to choose for React component testing? Why do frontend tests constantly break? I will try to answer all these questions during the talk.

OdessaJS Interview TechCorner

I use JavaScript from 2006. That time I did single page applications for IE6 in JS (it was ES3) and backend in Perl. JS was a pain. Does is better now? During my talk I would like to show fundamental difference between modern JS and Perl. How the same problems can be solved in different ways. Hope to give you a broader view on what programming languages can provide. Be prepared for interaction and to help me with simple tasks/problems in JavaScript :)

The architectural big ball of mud: why architecture is needed or how not to turn the Node.js backend into a big ball of dirt. WebbyLab CEO Viktor Tursky and Andrey Melikhov (Yandex.Money), moderated by Sergey Frolov (Front-End Technical Lead), talked about architecture in September at the JavaScript fwdays'20 conference.

Do you understand what Docker is? Is it safe? Are there containers in Linux? What about memory consumption and shared libraries? When will zombies appear in your containers? How to minimize docker image size? How do we use Docker for daily development? Let's dive deeper into this!

Docker deep dive for JavaScript developers

How to develop NodeJS apps effectively? I will tell you all details and share my personal experience on the whole process: from the very start and up to the production stage. You will also learn more about Docker, SDLC and 12 Factor App.

Effective NodeJS application development

Imagine that you are faced with the task of making a spreadsheet engine (no UI) compatible with MS Excel. And the engine's task is to run huge mathematical models for hundreds of thousands of formulas with performance close to the original Excel engine. We had to get everything possible from JavaScript. This is a project that cannot be realized without knowledge of algorithms, data structures, V8 internals.

NODE.JS GLOBAL SUMMIT

I've already talked about the working architecture of Web applications, but this is only part of the puzzle of effective development. This time I will show all details and share our personal experience on the whole process: from the very start and up to the production stage. I'll tell you how we approach the ideas of the "12 Factor App", how we use Docker, discuss environment deployment, security, testing,  SDLC.
Real-life experiences often differ from theory, so I always try to share what works in practice.

I've seen a lot of Perl applications. I see a lot of misunderstandings around architectural patterns. 99% of Perl tutorials do not cover this topic and limited to "hello world" apps. How to build a really large application? What to choose Monolith or Microservices? How to think about architectural layers? How does GraphQL influence my architecture? I will answer all of these questions.

Real world Perl applications architecture

Having 15-year experience in web development, I have tried my hands at dozens of validation libraries but didn’t manage to find the one to handle all my tasks. 5 years ago we decided to create a validator which will better than any other. Now LIVR supports a dozen of programming languages and it is battle tested in hudrends of projects. I will talk about the ideas behind, about architecture, use cases, pros and cons. Will show real examples.

6 ways to hack your JavaScript application

We start developing a project, we have to write a front-end and a back-end. How can we do this effectively? Will 12 factors help us? What about front-end development? How to use containerization correctly? How do I work with git branches? How to work with configs? What about the logs? Scaling? A million questions. I will tell you how we approach all this, what tools we use, what rakes we have stepped on.

We launched more than 60 projects, developed a web application architecture that is suitable for projects of completely different sizes. Here I'll analyze this architecture, will consider the issue of “monolith or microservices”, will show the main architectural errors that developers make.

I will tell you why you need JSON RPC and why I created another library. I'll show non-standard usage scenarios. Also, I'll analyze the architectural patterns that have proven useful and the decisions had to be taken during the development. Moreover, I’ll show what modern JS can offer us for developing libraries.
