Freelancer Overview

I am a backend engineer with over 4 years of experience designing and optimizing high-performance systems, with a strong foundation in Java, Spring Boot, and AWS. My work has involved building and modernizing microservices, integrating complex data pipelines, and ensuring data integrity and reliability across distributed systems in domains like fintech and logistics. I have hands-on expertise with SQL and NoSQL databases, RESTful and gRPC APIs, multithreading, and real-time data processing using Kafka. My experience in creating robust authentication, implementing efficient data ingestion utilities, and writing comprehensive test cases has given me a deep appreciation for high-quality, well-annotated data—critical for powering AI and machine learning solutions. I am passionate about leveraging my skills to support data labeling, annotation, and AI training data initiatives that demand accuracy, scalability, and reliability.
