Join us for another great event in 2025!

Please note that this year our CFP is by invitation only - contact us at info@developerdays.pl for a submission link if you feel you should be considered.
In-person sessions only please!

.NET DeveloperDays is the biggest event in Central and Eastern Europe dedicated exclusively to application development on the .NET platform. It is designed for architects, developers, testers and project managers using .NET in their work and to those who want to improve their knowledge and skills in this field. The conference content is 100% English, making it easy for the international audience to attend.

We are looking for seasoned speakers with highly technical sessions - this audience is demanding and unforgiving, so please make sure you do not inflate your session level. 300 and 400 level sessions are most desired, and we would be happy to consider "500" level. Very few 200 level sessions are accepted to this event.

PRE-CONS: 20 October 2025
POST-CONS: 23-24 October 2025 (two day post-cons!)

We cover return airfare and hotel for accepted speakers.
