    I specialize in designing custom-made machine learning solutions which are based on the top state-of-the-art developments and go beyond, if necessary. As a Ph.D. I have a scientific background, but my job over the last 13 years has always been related to the applied research projects: my passion is to make the latest scientific developments achievable and usable for solving real-world problems in working implementations. I have developed AI/ML/Deep Learning solutions in Python/Java/C/C++ for several applied research projects, including the ones realised in the international teams, with top European IT companies. They covered the topics such as: - voice biometrics (user identification) - access control through keyword verification - speech recognition and dialog systems for voice-controlled interfaces - network monitoring/fault detection and isolation - classification of vehicles base do the information from road cameras - traffic analysis in e-Health networks In those projects, I had the ability to work on the entire „production chain” of ML solutions. I am also aware that sometimes transferring the solutions from research to production requires introducing additional smart „tricks” to deal with the real-world problems. I specialize in designing new technologies that would have the performance close to the best-performing state-of-the-art solutions in the field or exceeding it. I also have experience in combining different open-source realizations, and re-using some of the existing software to prevent wasting the time on „reinventing the wheel”. However, I am always creative in proposing new designs and are willing to extend the boundaries of available technologies. I have been working several times as a part of an international team and was also leading small teams during project execution - so you can be sure that I am a team player and always take deadlines seriously. I can also lead a team of researchers/developers and provide technical guidance while following the project deadlines and milestones carefully.

    I'm a Python developer, CTO, and SaaS founder with over 10 years of real-world experience - not just writing code, but building and running a product that’s used daily by thousands of people. I started by writing the first lines of the backend (Python/Django), and over time I built the architecture, led the development team, made key infrastructure decisions, and kept a close eye on how the system performs, how it’s used, and what problems it’s meant to solve. My role naturally grew into CTO, but I’ve always stayed close to the code and the product. After more than a decade of building and growing this platform, I’m now looking for new challenges - opportunities where I can bring real experience to the table, contribute to meaningful software, and help teams build things that deliver value. If you need someone who understands how software actually lives, changes, and grows over time - not just in theory, but in production - I’m happy to help.
