What I'm looking for
I am a data-driven technologist with experience in data annotation, quality assurance, backend development support, and computer maintenance.

As a Principal I led strategic initiatives that increased enrollment 40% and drove a 100% pass rate in external exams; as a Computer Technician and Technical Assistant I implemented maintenance and network solutions that reduced downtime and boosted sales and performance metrics. At Hugo I analyze content, classify documents, and produce daily reports to support machine learning model validation.
I am proactive, detail-oriented and committed to continuous learning and professional development; I seek roles where I can apply annotation and QA expertise, technical troubleshooting, and leadership experience to deliver reliable data, streamline processes, and support growth.
