Freelancer Overview

Detail-oriented technical professional with a B.Sc. in Computer Science and experience supporting data-sensitive systems in banking and fintech. While my recent roles are in software development, the work aligns strongly with AI training data operations: applying strict rules to structured information, validating records, documenting edge cases, and troubleshooting issues to keep workflows accurate and consistent. I’m comfortable working with complex datasets and systems where precision, confidentiality, and auditability matter. I bring strong data-handling and quality discipline, including consistency checks, error identification, and clear documentation for feedback loops. My technical stack (SQL and NoSQL databases, API-based systems, Git-based workflows) supports efficient handling of large volumes of structured information and collaboration in production environments. Key qualifications include hands-on experience building and maintaining loan/savings transaction workflows, strong attention to detail, and the ability to follow detailed guidelines and deliver high-quality outputs under QA review.
