About Us

Sparkbit was created to be a great workplace for exceptional developers. A place where people enjoy coming, as they know the atmosphere is friendly, the learning experience is mutual, and the work-life balance is untacked.

Business core

We thrive on working on challenging projects. Innovations and complex systems are what pushes us towards excellence forcing constant personal growth. That's why our main focus covers three areas of software development.

Machine Learning

We started as software engineers with academic backgrounds. Adding the data science part allowed us to conduct ML projects end-to-end using our own MLOps workflow.

R&D Prototypes

We build bridges between science and commerce by planning and running meaningful experiments based on research and our own experience. All the innovations are born through a trial&error process, but we simply don't give up.

Challenging software systems

Think of it as our foundation, as most team members come from the backend environment. Our backend- and architecture-focused mindset allows us to design and build complete systems for non-trivial data processing such as time-series or multi-sensorial IoT data.
