Freelancer Overview

Full-stack software engineer with 5+ years of experience building production web applications across fintech, SaaS, gaming, and media. Experienced in designing scalable backend systems, REST and GraphQL APIs, authentication systems, real-time applications, and frontend platforms using React, Next.js, Node.js, TypeScript, PostgreSQL, and Redis. Although I do not have formal data labeling experience yet, I have strong analytical and technical problem-solving skills from building and maintaining production systems. My background includes debugging complex systems, reviewing code, validating data flows, testing application behavior, and working with structured datasets and APIs. I am particularly interested in AI evaluation, LLM workflows, and AI-assisted development tools, and I am confident in my ability to quickly adapt to AI training and annotation tasks that require attention to detail, consistency, and technical understanding.
