Thoughtful Engineering, Reliable Software

Senior Software Engineer solving complex problems and building software that lasts.

Selected Work

Evolving Software That Already Matters

For nearly a decade, I have played a key role in evolving a mature enterprise system by expanding its capabilities, modernizing its technology, and addressing the complex challenges associated with software that people rely on every day. Real-world systems. Meaningful constraints. Measurable improvements.

Strengths

Where experience makes a difference.

Experience has taught me that great software is built with intention, improved through collaboration, and designed to last.

Built with Intention

Quality goes beyond making code work. I focus on writing clear, maintainable code while following sound engineering practices. My goal is to create lasting solutions, not quick fixes. I pay attention to the details that make software reliable, consistent, and built to last.

Modernize with Purpose

I lead front-end improvement initiatives focused on maintainability, accessibility, and modern best practices. By refactoring legacy React components and enhancing team standards, I turn technical debt into a solid foundation for sustainable future development.

Strengthen the Team

I support engineers and product teams by bringing clarity through collaboration, guidance, and practical execution. I share knowledge, build trust, and improve team practices, making complex projects easier to navigate and more sustainable over time.

About

Always curious. Always learning.

I love to travel and explore new places, whether that involves hiking a new trail, wandering through an unfamiliar town, or finding a beautiful spot to spend the day. Having lived in Croatia and now calling Florida home, I have developed a strong appreciation for both European charm and seaside life.

Family is at the center of my life. Some of my favorite moments are the simple ones: discovering new places together, enjoying the outdoors, and making the most of wherever we are.

I’m also a big fan of green tea, engaging conversations, and learning something new whenever I can.

My curiosity drives everything I do; I enjoy understanding how things fit together, asking thoughtful questions, and finding ways to improve things.
