About

My career began with a deep pursuit of excellence in music, where international competition honed my discipline, attention to detail, and performance under pressure. This foundation shaped my approach to technology: combining the artistry of design with the precision of engineering.

In 2020, I transitioned into software development, quickly mastering ReactJS and TypeScript. I applied these skills immediately to build a custom, full-scale, fully featured blog and website for a local company, learning firsthand how to solve real-world business challenges through elegant, scalable frontend solutions.

Driven by a relentless commitment to growth, I built project after project, mastering modern frameworks and deepening my understanding of system architecture, data modeling, and high-performance UI/UX design. Joining teams like the National Police Data Coalition expanded my expertise in building complex, maintainable applications within fast-moving professional environments.

Today, I am at the forefront of frontend engineering — leading major projects like TuneSplit, enhancing AI models at DataAnnotation through deep technical rigor, and continuously pushing the boundaries of what scalable, user-centric applications can achieve. I blend technical mastery, data-driven intuition, and an entrepreneurial mindset to deliver products that are as impactful as they are beautiful.

Beyond code, I pursue challenges that sharpen both mind and body — whether staying active through sports, or finding inspiration in music with my two cats by my side.
