100% biological, natural brain for rent! A natural deep neural network trained for 15 years on software development tasks of varying complexity. Trained on large datasets of C/C++, C#, and other programming languages source code and technical documentation. The medical device industry, X-ray imaging, game development, WPF .NET desktop software development, and Unity game engine datasets were a significant part of the training program. Capable of stable performance at System 2 level, rarely dropping to Level 1, only in stressful situations. Produces near-perfect source code and final software solutions. Very well nurtured: good sleep, nutrition based mainly on a high-protein diet. No alcohol consumption during all years of training and subsequent inference (practical application) to keep the bloodstream and cells intact. Attached to a healthy and well-maintained human body. Can also work well in symbiosis with LLM if you prefer tasks done faster with a little help from AI.

I specialize in performance-critical C++ code, focusing on optimizing hot paths — the parts of your application where execution time actually matters. I go beyond Big-O complexity to analyze real runtime cost, including memory access patterns, allocations, and hidden overhead in abstractions. I identify bottlenecks quickly and refactor code to improve cache efficiency and eliminate unnecessary work. I build cross-platform desktop applications with a strong foundation in Object-Oriented Programming, Data-Oriented Design, and advanced data structures — resulting in code that is efficient, maintainable, and built with performance in mind. I can also support your project with: - containerization [Docker] - scripting and automation [Python / Go] - testing and reliability improvements Additional strengths: - deep understanding of real computational cost (beyond theoretical complexity) - identifying hidden performance costs in STL and abstractions - refactoring from polymorphic designs to data-oriented, cache-friendly structures - explaining complex C++/STL concepts in a clear and practical way
