I’m a DataOps Engineer specializing in 👨‍💻🖥️📌 [ Data management, AI data annotation, computer vision datasets, web scraping, and workflow automation ] .📌 I work with ⏭️[ Excel, Google Sheets, MongoDB ] ⏮️for data operations, data entry, lead generation, and data management. For AI and computer vision, I build and annotate machine-learning datasets using [ CVAT, Roboflow, and Label Studio] , including bounding boxes, segmentation, keypoints, classification, and tracking. I also use - ✅Python (Scrapy, Selenium, Pandas) for web scraping and data processing, and N8N for workflow automation. I focus on accurate, structured, and reliable data that is ready for business or machine-learning workflows.

In this clip, I’ve annotated multiple real-world objects including: • Vehicles (cars, buses, vans) • Pedestrians (men, women) • Traffic elements (lights, signs, bus stop shades) • Cyclists & motorcyclists
The goal? High-quality, structured data to power smarter computer vision models

Intelligent Transport Annotation

Developed a structured database of 100+ US SaaS startups featuring founder information, company websites, LinkedIn profiles, contact details, company size, industry classification, and outreach notes. Designed for lead generation, sales prospecting, and market research purposes.

Produced high-accuracy transcriptions and annotations for conversational audio recordings used in AI speech recognition and voice assistant training. The project involved speaker identification, timestamp verification, speech-to-text transcription, handling overlapping dialogue, noise recognition, and strict adherence to detailed annotation guidelines to ensure high-quality training data for machine learning models.

This is a scraping project that I successfully extracted 10000+ product data [Product Name, Price, Discount, Rating, Image url, Seller score, Details ] , I used python frameworks like scrapy to extract the data from the website and pandas to clean the extracted data ,get rid of duplicates and save the extracted data to a structured excel file

**Soccer Semantic Segmentation (Polyline Annotation) – CVAT**

This project focused on semantic segmentation of soccer scenes using CVAT's Polyline tool. I precisely outlined soccer players and the ball by tracing their visible boundaries, creating detailed object masks suitable for pixel-level computer vision tasks.

The annotations were designed for AI models used in player detection, player tracking, scene understanding, and sports analytics. Special attention was given to overlapping players, object boundaries, occlusions, and label consistency to produce accurate, production-ready datasets.

Soccer Semantic Segmentation

Built an end-to-end workflow that fetches live PageSpeed data, extracts and structures key performance metrics, stores them in Google Sheets, and delivers automated reports.
Runs on schedule. No manual checks—just consistent, reliable performance tracking.
