Freelancer Overview

Data labeling, audio analysis, chatbot rating, AI image analysis, AI billing, in areas or projects mainly related to autonomous vehicles in both 2D and 3D (LiDAR), logistics (parcel handling robots), neuroscience, AI agriculture (everything related to detecting ripe fruit ready for market using AI), I have worked in many areas of AI training. Starting with Appen, then my greatest experience was at Remotasks (Scale), currently at Toloka, but I have also worked on projects at LXT (LDP) and Shaip AI. The number of projects is endless, but I'll give you a few examples: Alpaca (Amazon and its Scout delivery robot), Rhino invoice labeling, Baboon Semseg and Baboon MOD (bounding box, extensive experience), Goat Linking Cuboids (fisheye and regular camera), Goat videobox traffic light, invoice box annotation, object verification, Zebra lidar linking polygon, Lucid dynamics objects (great experience), Snowberry, Attic Stick, Venus, Emu Cuboids, Dragonfruit (AI for restaurant menus), Beefood, Necklace Theory, Lane Segmentation, Electra Segmentation, Horizon Semseg, Cape Mattock, Payment Antelope, GTIN tagging, and many, many more. At Remotasks, we work on countless projects daily, all mixed together. New ones were always appearing, old projects were repeated—very varied and a huge amount of work, nonstop. I dedicated up to 18 hours a day. But it was incredible; you learn so much. At Appen, it was mostly simple projects like classifying companies and advertising.

Baboon Mod

Scale AIImageCuboid
We had to annotate the nearest vehicles in a specific way, using perfect cuboids, establishing the correct inclination and their relative position to other vehicles. It was a long and very interesting project, with thousands and thousands of annotation tasks. Even now, it's difficult to remember every single project. There were just too many.
