I'm a passionate software engineer with a deep love for Computer Science. My professional life revolves around tackling complex system-level challenges, managing codebases, and building scalable infrastructure.
- Engineering: Deep focus on system architecture, infrastructure management, and automation.
- macOS Development: Expert in native application development, system-level integration, and complex CI/CD pipeline orchestration.
- Large-scale Systems: Extensive experience in maintaining and evolving codebases and supporting robust, scalable backends.
- Scientific Growth & Visualization: Actively expanding my expertise in mathematics and physics, with a focus on data visualization and high-performance computational modeling.
- Leadership & Analytics: Driven by a data-centric approach, I enjoy optimizing team processes and solving intricate architectural puzzles.
You can find my hobby projects here. Note: I don't spend much time writing open-source code, as most of my "real-world" engineering work happens behind closed doors in large-scale corporate environments.
