About

I am an iOS, iPadOS, and watchOS developer with experience building online fitness training platforms, instant messaging apps, and CRM systems.

With strong expertise in streaming, Bluetooth integration, and real-time communication, I focus on transforming product requirements into stable, user-friendly applications.

I emphasize SOLID principles and apply Domain-Driven Design (DDD) pragmatically to improve maintainability, scalability, and long-term code quality. I actively embrace Agile (Scrum) methodologies and am highly engaged in AI-driven software engineering workflows.
