OBJECTIVE
Desired Position:
Senior Software Engineer

SUMMARY
With over 20 years of experience in programming and around 17 years of hands-on expertise in native mobile development and backend technologies, I thrive in projects where thoughtful, efficient solutions, high product quality, and well-structured development processes are key. My core focus is on C++, which I consider an excellent foundation for working with higher-level languages such as Java, Python, and C#. While I have experience with a wide range of technologies, including web and .NET development, C++ remains my strongest and most comfortable domain, allowing me to tackle low-level and system programming with ease. I have collaborated with companies like L1 Technologies and Skyhook Wireless, delivering impactful results across mobile/embedded systems and desktop software development.
To ensure I remain versatile and open to diverse project opportunities, I consistently update my skills, particularly in backend development. My expertise in .NET and Python/Django allows me to effectively work on projects related to web technologies while leveraging my deep knowledge of C++ for performance-critical or system-level applications.
In addition to my software development skills, I have a solid background in electronics. While it’s mostly a personal interest, I can read and reverse-engineer electronic schematics, work with MCUs (microcontrollers), and understand the fundamentals of embedded systems. This combination of programming expertise and electronics knowledge enables me to explore opportunities in system-level programming, embedded development, and hardware-related software tasks.
Despite my extensive experience, I’m open to taking on mid-level positions, driven by the desire to continuously learn and apply my skills to new challenges. Whether it's optimizing system performance, developing infrastructure, or contributing to backend solutions, I bring a versatile and adaptive approach to development.
Currently, I also serve as a part-time lecturer at the National Technical University «Kharkiv Polytechnic Institute», where I teach courses on programming, web technologies, and data science. Teaching allows me to stay updated on the latest developments in the field, and it complements my professional work by providing new perspectives on technical solutions.
There is a list of responsibilities that I handle till that moment:
— Provision of the architectural decisions.
— Assisting with architecture, IoC, DI, CI/CD support, unit tests implementation.
— Having experience in geolocation, dealing with multithreading and system programing, data processing.
— Source code adaptation for different toolsets, including mingw/gcc, toolsets for embedded platforms, etc.
— Participation in the interviews for candidates from the market.
— Communication with cross-functional teams.
— Developing course syllabi, assignments, and testing materials for students.
— Supervising thesis and diploma projects for university students.
