Freelancer Overview

I am a software engineer with hands-on experience in building scalable platforms for data processing, machine learning, and NLP applications. My background includes developing systems for large-scale time-series data analysis, anomaly detection, and interactive visualization using Java, Spring Boot, and Python, as well as implementing NLP-driven features like plagiarism detection. I have worked extensively with data pipelines, RESTful APIs, and backend integrations, supporting reliable data ingestion, transformation, and quality assurance. My experience collaborating on diverse teams, combined with my skills in Python, SQL, FastAPI, and open-source contributions, has given me a strong foundation in managing and preparing high-quality datasets for AI training and analytics. I am passionate about leveraging my technical expertise to improve the accuracy and efficiency of AI models through precise data annotation and labeling practices.
