Software Development Services in Warsaw, Poland
Sparkler Soft is a software development agency based in Warsaw, Poland, building native mobile apps, web platforms, machine learning systems, and cloud infrastructure for companies across Europe. We are an experienced team led by senior specialists, combining technical guidance with practical product delivery.
Our approach starts with a technical discovery phase before any code is written: mapping the architecture, the constraints, and the metrics that will define success, so estimates are realistic and assumptions are explicit. We prefer two-week sprints and adapt the cadence to the project. Video reports, test results and shared task trackers give you a clear view of progress, decisions and remaining work.
Below are the six core services we deliver — iOS and Android app development, web services and API development, machine learning, DevOps & cloud infrastructure, and technical consulting & architecture. Each page covers our approach, what's included, the technologies we use, and answers to the questions we hear most often. If your project spans more than one of these, that's normal — most of our work does.

We had a great experience working with Sparkler Soft on our real estate selection app. Sergey, the CEO, was very involved in the process and made sure everything moved in the right direction from start to finish. The team was skilled, professional, and easy to work with, and they handled the project with great care and attention to detail. All the work was done well, and the final result fully met our expectations. Communication throughout the project was excellent - fast, clear, and always at a very high level. We would definitely recommend Sergey and the Sparkler Soft team to anyone looking for a reliable partner for cooperation.
