How we work with speakers
Paper submission
We do not accept sales pitch style presentations. We are looking for people passionate about performance, who are able to speak effectively and from experience and who understand our audience of developers.
The program is designed by the developer community, representatives of large companies from around the world, and by tech developers and community activists. The selection of papers is multi-layered and complex — the Program Committee selects the best papers from the received applications unanimously according to several criteria.
Communication with program committee
A shepherd from the Program Committee may be assigned if there are questions regarding your paper.
Competition and decision making
Program committee makes final decision by the stated deadline. Sometimes we might need more time due to increased competition among submitted papers. The decision is primarily based on several criteria - applicability outside of speaker's context, up to date, uniqueness (the paper should not be already presented at previous conferences).
Final decision
Each speaker will be contacted by program coordinator and informed on the final decision of the committee. For any questions prior or past that moment - please, feel free to contact us!
