About

Professional summary

I am a detail-oriented Data Annotation and AI Evaluation Specialist and software developer with over five years of experience supporting AI training, search quality, content classification, fact-checking, and RLHF-oriented evaluation projects.

I annotate and validate image, text, multimodal, and search-result data against detailed guidelines. I am experienced in reviewing outputs for consistency, identifying edge cases, documenting labeling decisions, and protecting dataset quality through careful quality assurance.

I work effectively in remote, deadline-driven environments and communicate clearly with project leads and distributed teams. I bring strong written and verbal English communication, active listening, research, documentation, and feedback-integration skills.

Alongside AI evaluation work, I develop full-stack web products using React, Next.js, TypeScript, Node.js, Python, FastAPI, PostgreSQL, and Drizzle ORM. I have built authenticated, database-backed applications and a Python desktop application for real-time voice processing and local GPU model training.

I am self-directed, adaptable, and committed to accuracy, confidentiality, professional ethics, and continuous improvement. I am interested in remote opportunities involving AI data operations, AI evaluation, quality analysis, annotation, and software development.
