Yehor Chernenko

I mentor and guide mobile engineers at different stages of their careers. For those aiming to break into Big Tech, I provide structured preparation for technical interviews, system design for mobile platforms, and industry-specific expectations. I help mid-level engineers grow into senior-level professionals. This involves coaching on technical excellence, leadership skills, cross-team collaboration, and developing a strong product mindset. I focus on helping engineers not only deepen their technical expertise but also build the confidence and communication skills needed to influence and lead. I consult on large-scale iOS architecture that ships to millions of users. My consulting work spans from designing scalable, maintainable, and testable iOS systems to guiding teams on implementing best practices in modularization, performance optimization, and modern iOS frameworks. The emphasis is always on building solutions that are not just elegant on paper but are proven in production at scale.
