Freelancer Overview

With 5 years of experience as a .NET developer, I bring a strong foundation in backend engineering, large-scale data handling, and secure data processing—skills that directly support AI training and high-precision data annotation workflows. I have extensive hands-on experience designing scalable enterprise web applications, building RESTful APIs, optimizing SQL Server/MySQL queries, and managing structured datasets with high accuracy and integrity. Alongside my backend expertise, I have worked with multiple industry-leading data labeling platforms including Label Studio, Labelbox, Dataloop, CloudFactory, AWS SageMaker Ground Truth, Google Cloud Vertex AI, and several internal/proprietary annotation tools. I am familiar with end-to-end annotation pipelines, quality review cycles, and guideline-driven labeling standards. My domain exposure spans Technology & Internet (web applications), Government Services (property & tax form processing), and Education/EdTech (AI training workflows). I have worked with diverse data types including computer code, documents, and text, and I am proficient in key labeling tasks such as classification, text generation, summarization, translation/localization, and programming/code-based annotations. I focus heavily on data validation, quality assurance, and consistent labeling logic while collaborating with cross-functional teams. Thanks to my backend development background in C#, ASP.NET Core, Entity Framework, SQL, and tools like Azure DevOps, Git, I understand how annotated datasets integrate into machine learning pipelines and how data quality impacts AI performance. Overall, I bring a rare combination of technical depth, structured data experience, and annotation workflow expertise, making me well-suited for high-accuracy AI Trainer and Data Annotation roles.
