Most AI projects fail because of two things: messy training data, slow and manual workflows. I fix both. I am an AI workflow automation engineer and data annotation and labeling expert with over 5 years of experience building, labeling, and optimizing datasets for machine learning models. I sit exactly between the raw data and the pipeline engineering. By combining local Python environments with advanced dev tools like Claude Code and Antigravity 2.0, I don't just label or annotate data; I write the code to automate the pipeline. What I execute: • Pipeline Automation: Build custom web tools, API integrations, and agentic workflows using n8n, Make and Zapier to eliminate manual data bottlenecks. • Data Scripting: Write custom Python scripts (OpenCV, NumPy, Pandas) to parse, clean, transform, and format massive datasets. • High-Precision Annotation & Labeling: Deliver flawless 2D/3D bounding boxes, polygon/semantic segmentation, LiDAR point clouds, and multi-camera video tracking. • GenAI & LLMs: Handle RLHF response ranking, preference modeling, prompt engineering, and Human-in-the-Loop (HITL) validation. • Core Tools: CVAT, Label Studio, Roboflow, and Scale AI. I’ve logged thousands of hours working on autonomous driving data, multi-camera tracking systems, and text classification models. I work independently, follow strict guidelines, and maintain a 99%+ accuracy baseline. If you have a workflow bottleneck that needs engineering or a critical dataset that needs to be annotated or labeled for your next sprint, send me an invite and let’s talk.
