πŸ‘©πŸ»β€πŸ’» About me

Hi there πŸ‘‹πŸ½ My name is Tirza.
A little bit about me β€” I come from a diverse background and I'm someone who enjoy working at the intersection of technology and design. I started my career as assistant project manager on deep-sea scientific research, and later moving into roles in digital and business support at European Commission (DG INTPA).

These experiences taught me to adapt quickly, solve complex problems, communicate clearly, and build strong collaborations in multicultural and international environments. I’m a curious and fast learner who thrives in creative and collaborative environment. I enjoy working on projects that use technology to solve real problems and create meaningful impact, whether by building digital solutions, supporting organisations, or improving user experiences.
