What I'm looking for

I am looking for a role that encourages innovation, teamwork, and professional growth.

As a proactive and goal-oriented professional, I have extensive experience in developing and maintaining projects, primarily within the banking sector. My journey has allowed me to take on leadership roles, guiding teams and contributing to the research and development of emerging technologies.

Currently, I serve as a Senior Frontend Developer at C&A, where I utilize Angular 17 to enhance applications for product resellers. My previous roles have equipped me with a robust skill set in both frontend and backend development, including technologies like Node.js, MongoDB, and AWS. I thrive in collaborative environments, employing methodologies like Scrum to deliver high-quality results.

With a strong foundation in system engineering and a commitment to continuous learning, I am eager to leverage my skills in a challenging new role that fosters innovation and growth.
