About Myself
Hello! I’m Sabrina, a freelance SAP ABAP Developer focused on building efficient, maintainable, and result-oriented enterprise solutions.
I’ve found in SAP the perfect space to combine logic, creativity, and purpose — an environment that drives my professional growth and motivates me to continuously enhance my technical, analytical, and solution design skills.
My work focuses on developing robust and scalable programs following Clean Code principles, prioritizing performance optimization and code clarity. I enjoy working in agile environments, collaborating with multidisciplinary teams to create solutions that address real business needs and improve process efficiency.
With a foundation in Food and Environmental Engineering, I bring a systems-thinking mindset and a continuous improvement approach that strengthen analytical thinking and structured problem-solving.
Currently building my professional portfolio, I’m open to new challenges where I can keep learning, contribute value, and create meaningful impact through innovation and teamwork.
