Freelancer Overview

I am a passionate software engineer with hands-on experience in building scalable, data-driven applications and implementing robust backend systems. My background includes designing and optimizing databases, developing RESTful APIs, and working with large datasets in both SQL and NoSQL environments such as Oracle Database, PostgreSQL, MySQL, and MongoDB. I have contributed to projects where high-quality data management and processing were critical, such as an e-commerce platform serving thousands of users and a collaborative task management system that improved team productivity. My technical skills span Java, Python, and JavaScript, and I am proficient with cloud and DevOps tools like Docker, AWS, and CI/CD pipelines. I thrive in agile teams where attention to data quality, accuracy, and process automation are essential, and I am eager to apply my expertise to data labeling and AI training data initiatives.
