Labeling Experience

AI-Based Product Developer, Robotics Engineer & Researcher, Ethiopian Artificial Intelligence Institute (EAII)

Don't discloseData Collection

Worked on multiple AI-based robotics and smart energy products, including prototyping wiring/control systems and conducting machine-learning research for smart grid applications. The experience implies hands-on development of data-generation workflows (e.g., sensor/robot telemetry and research datasets) used to train and evaluate AI systems. Responsibilities also included coaching students on robotics and IoT fundamentals with hands-on projects. • Designed and developed wiring and control prototype for an AI-based guest assistive robot. • Conducted research on machine learning techniques in smart grid systems. • Developed AI-based vacuum cleaner robot, AI-based smart blind stick, and additional vehicle prototype systems. • Coached summer camp students on robotics and IoT fundamentals with practical projects.

2021 - Present

Associate Researcher II, Technology & Innovation Institute

Fine-tuning

Developed IoT- and electronics-focused systems while providing technical training and project support across departmental efforts. Although explicit labeling/annotation tasks are not stated, building IoT and automation solutions typically requires collecting structured signals and iterating on data-driven models. Work included designing electrical components and implementing devices that could produce labeled telemetry for later AI use. • Designed electrical components for a golf cart electric vehicle prototype. • Developed an automatic and mobile disinfectant device. • Built an IoT-based theft protection system for distribution transformers. • Provided technical training and support across departmental projects.
