What I'm looking for

I seek roles building usable, impactful web systems with emphasis on accessibility, collaboration, and opportunities to lead projects and optimize processes.

I am a technology specialist with five years of experience in data analysis and systems development, delivering solutions that optimize processes and add measurable value. I build accessible, usability-focused web applications—using Python, PHP and other modern tools and lead projects that improve efficiency for public sector and small-business clients.

I have practical experience designing workflow systems that reduced administrative delays and developing a LIBRAS translation tool to enhance accessibility for students and educators. I collaborate remotely with clients to define goals, document requirements, and deliver tailored software solutions while maintaining strong communication and adaptability.
