What I'm looking for

I'm interested in QA, data analysis, and technology solutions focused on automation and continuous improvement.

At Versatile, I validated and enriched visual data in real time, checking for inconsistencies and escalating cases outside protocol.

At Appen, I labeled and segmented image data for computer vision and machine learning projects, including body and facial regions and vehicle types. I also validated data quality against project guidelines.

During my practical placement with Interacpedia • Convenio SENA & EVERIS, I helped develop a hotel reservation management solution through requirements analysis and functional documentation. I have a software engineering degree and training in data science, programming, AI, and cybersecurity.
