Freelancer Overview

While my background is primarily in software engineering, cloud infrastructure, and backend systems rather than formal data labeling roles, I bring strong transferable experience that aligns well with AI training data work. I have built and supported real-time data pipelines using Apache Kafka, worked with multiple database systems including MongoDB, DynamoDB, MySQL, and PostgreSQL, and developed scalable backend services in Go, Node.js, and Python. In my Optimile project, I helped design a cloud-native microservices architecture and containerized services, including Python-based ML components, which gave me hands-on exposure to structured data flow, system reliability, and automation—skills that are highly relevant to preparing, validating, and managing high-quality AI training data. What sets me apart is my strong technical foundation in data handling, automation, and quality-focused engineering. I have experience automating deployment and infrastructure through AWS CloudFormation and Shell scripting, monitoring systems with Prometheus and Grafana, and working in Agile team environments with Git and Docker. As a Computer Science student at Thammasat University with coursework in databases, distributed systems, and cloud computing, I am well-equipped to quickly learn annotation guidelines, maintain consistency, and contribute effectively to AI data operations that require accuracy, scalability, and attention to detail.
