I am a Senior Software Engineer specializing in modern C++ (C++17/20) and R&D. I design and build high-performance, memory-efficient systems for companies that need speed, reliability, and scalable production code. With a Master's degree in computational mathematics and experience engineering solutions at the enterprise level, I bring strong analytical problem-solving to every project. My core focus: • Performance-critical C++ (multithreading, low-latency systems, memory management) • Custom algorithms & machine learning (probabilistic algorithms, fuzzy classification, inference optimization) • Desktop application development (Qt/QML) • Systems architecture & Linux environments What I can help you with: • Optimizing existing C++ codebases (CPU, memory, concurrency) • Porting ML models (Python to C++) for high-speed inference • Building backend systems for Linux/embedded environments • Developing advanced UI components and rendering stacks Tech stack: C++17/20, STL, multithreading, Qt/QML, CMake, Python, Linux/Ubuntu I prioritize clean architecture, measurable performance improvements, and clear communication. If your system needs to be faster, leaner, or more scalable, let's discuss how I can help.

Computer programming is not just my profession, it's my passion. Striving to do my best on every project I always try to go one step beyond, and expand my knowledge. From small personal projects of getting into protected mode in x86-assembly under DOS and drawing some Bresenham lines and midpoint circles on screen(0A000h), pixel by pixel, or programming an AVR microcontroller, in C, to flash some LEDs and move some servos around upon a press of a button; all the way up to developing multiplatform applications with ActionScript3/Starling or C#/Unity3D in a team of 3-6 people, working with artists, project managers and QA; I'm accustomed to a wide spectrum of programming practices and always ready to dive into anything, eager to learn something new. Now, this last sentence was really long and I wasn't quite sure how to punctuate, so I've tried some semicolons... intuitively... writing is my hobby, and I'm not particularly good at it.
