KenyaWhat I'm looking for
I’m an IT & Data professional with 4+ years of combined experience across networking & administration, data annotation, data analysis, and software systems. I’ve worked on large-scale 2D/3D annotation using polygon and bounding-box tools, and I built deep expertise in polygon annotation workflows for high accuracy and consistency.
I’m also hands-on with LiDAR annotation (vehicles, pedestrians, and static objects) and served as a trainer who reviewed and rated co-workers’ submissions to ensure quality and fairness. Beyond data work, I installed and maintained fiber-optic networks, educated clients and teams on troubleshooting, and contributed to ERP improvements to reflect online and bank fee payments in real time.
