We invite you to speak!

We are pleased to invite foreign speakers to come and speak at the conference and share their developments and experience with the Russian audience. Every year, up to a quarter of our speakers are the best minds from around the world. We already had representatives from Google, Facebook, Yahoo, Amazon, Microsoft, Percona, Etsy, Booking.com, Twitter, Dropbox, and many other prominent companies.

Watch the best HighLoad++ English talks:
We are not limited to just Western companies — in 2015, the first Chinese-speaking presenter in Russia spoke about the use of MySQL at Alibaba. In one track you can meet representatives of media giants from different sides of the world — BBC and Al Jazeera.

We are very interested in hot speeches by community representatives, open source project contributors, technology developers, database developers, and developers of any large projects, including non-web projects.
Visiting Russia
You may prepare your speech in either English or Chinese; we will provide simultaneous interpreting for our listeners.
For foreign speakers, we will fully cover the costs of accommodation, airfare, and visa fees.
We are confident that you will find your trip to Russia both interesting and useful, and that your experience will be met by our audience with gratitude and focused attention.
Russian engineers have preserved the high qualification inherited by us from the Soviet Union. They used to build rockets but now their accomplishments include Yandex (4th in the world among search engines, Mail.Ru (a mail service with 100 million active users), VKontakte (250 million registered users), Telegram (100 million users), and Badoo (more than 300 million accounts).
Our programmers have taken part in many international open source projects and work as database and web server developers. One of the most striking examples is the web server Nginx, which holds second place in the use of active web sites (after Apache, of course:).
Code of Conduct

We adhere to the standard rules outlined in the Code of Conduct.

Our conference is dedicated to providing a harassment-free conference experience for everyone, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or technology choices.

Sponsorship Information
The conference is purely technical — our visitors are well versed in the intricacies of programming, can form queries for databases and read execution plans for these queries, understand and apply various architectural patterns for the design of high-load projects with traffic of up to hundreds of thousands or millions of visitors per day.

We want to talk with speakers in one language, so we don't expect evangelists who talk about how you company or technology is cool. We expect developers of this technology or architects of your project from whom we can learn a lot. We don't care that you have 20,000 servers, but we would love to know how you deal with them in your operations. We are not interested to know that you have 20 million visitors, but we are very curious as to which architectural solution allows you to withstand such a load.

We even recommend placing engineers (and not just salespeople) at company stands.

By the way, as part of the conference there will be a technological exhibition where many of Russia's service providers, large companies, and technologies will be presented. At various points in time, our exhibitions have hosted the work of Microsoft, Percona, Google, Badoo, Zabbix, and many international companies and communities.

To receive a commercial offer to participate in the exhibition, please write a letter and tell us about your proposition at organization@ontico.ru.
