Nice to Meet You

I'm Réka — a Business Analyst with a passion for turning complex challenges into elegant solutions. My engineering background gave me the analytical mindset, but it's my curiosity and love for continuous learning that keeps me growing every day.

Beyond Work

When I'm not optimizing processes or writing user stories, you'll find me outdoors pushing my limits. I believe that the discipline, focus, and teamwork I practice in sports directly translate to how I approach my work.

Winter Adventures

Snowboarding and skiing in the mountains — there's nothing like the freedom of carving through fresh powder.

Climbing & Bouldering

Whether it's indoor bouldering or outdoor rock climbing, I love the problem-solving aspect of finding the perfect route.

Longboarding

My favorite way to clear my head and enjoy the city streets on wheels.

Fitness & Cycling

Regular gym sessions and bike rides keep me energized and ready for new challenges.

Exploring the World

I'm passionate about traveling and discovering new cultures. Learning languages opens doors to deeper connections — that's why I speak Hungarian, English, and German. Every trip teaches me something new about adaptability and perspective.

What Drives Me

The same dedication I bring to conquering a climbing route or navigating a challenging ski slope is what I bring to every project. I believe in persistence, teamwork, and finding creative solutions — whether I'm on a mountain or in a meeting room.
