Freelancer Overview

With over 8 years of experience as a backend engineer, I have worked extensively with large-scale data systems, focusing on data integrity, efficient data processing, and API development for high-traffic applications. My expertise includes designing and optimizing databases (MongoDB, PostgreSQL), building scalable microservices, and implementing robust data pipelines that ensure reliable data flow between systems. I have led backend architecture for projects involving financial transactions, digital currency, and real-time interactions, where accurate data handling and traceability were critical. My background in distributed systems, AWS cloud services, and event-driven architectures has equipped me to support data annotation workflows and AI training pipelines, ensuring high-quality data management and seamless integration with machine learning models. I am passionate about leveraging my backend and data engineering skills to enable effective data labeling and annotation processes for AI-driven applications.
