What I'm looking for

I seek roles where I can apply AI model training and computer vision expertise alongside full-stack development, contributing to product impact and collaborative teams.

I am an Artificial Intelligence specialist with practical experience training models, processing 2D/3D LiDAR data, and producing high-quality annotated datasets for computer vision and audio/video tasks.

I build web applications using HTML, CSS, JavaScript, React, Node.js, and MongoDB, integrating front-end and back-end systems while applying security best practices and performance optimizations.

My background includes digital marketing, graphic design, and team management, where I led operations, coordinated projects, and executed campaigns that improved engagement and ROI.

I work across NLP/LLM evaluation, OCR, speech-to-text, and advanced annotation techniques (bounding boxes, polygons, segmentation, 3D point cloud annotation) to deliver accurate, production-ready datasets and AI solutions.
