About Me

My journey in frontend development

The Beginning

My transition to the React/TypeScript ecosystem marked a turning point. Focused on building high-performance interfaces, I embraced modern patterns, state management, and component-driven architecture to deliver exceptional user experiences.

Specialization

Currently pursuing a Postgraduate degree in Mobile Devices, deepening my expertise in mobile architecture, React Native patterns, and cross-platform development strategies that bridge web and native experiences.

Parallel Interests

Beyond web development, I explore game development with Godot Engine and C#, applying logical thinking to puzzle mechanics. My daily driver is Linux (Pop!_OS), reflecting my appreciation for customizable, efficient workflows.

The Human Side

As an amateur marathon runner, I've learned that software development mirrors endurance sports: both require long-term commitment, consistent daily effort, and the resilience to push through challenging moments. Every line of code is a step toward the finish line.
