Freelancer Overview

Senior Backend Developer and Systems Architect with 17+ years of freelance consulting experience across FinTech, eCommerce, Healthcare, and SaaS. I specialize in PHP 8, Python, Node.js, MySQL, PostgreSQL, Redis, Apache Kafka, and distributed systems design - delivering high-availability architectures at scale. I bring deep domain expertise to AI training data tasks including code generation review, LLM output evaluation, reasoning step verification, and RLHF preference labeling. My engineering background allows me to evaluate AI-generated code with production-level accuracy, identify hallucinations in technical responses, and red-team AI systems for security and logic flaws. I have contributed to structured annotation workflows, developed evaluation guidelines, and built Python-based automation tooling to support data pipelines - making me a high-signal contributor to any AI training project.

Senior Backend Developer - Code Generation Review and LLM Evaluation

TextRLHF
Applied 17+ years of backend engineering expertise to review and evaluate AI-generated code across PHP, Python, Node.js, MySQL, and distributed systems domains. Tasks included verifying correctness of AI code completions, identifying logic errors and security vulnerabilities (OWASP Top 10, mTLS, JWT), ranking model outputs by quality, and providing structured preference feedback for RLHF pipelines. Also evaluated AI explanations of distributed systems concepts (CAP Theorem, Raft consensus, CQRS, event sourcing) for technical accuracy and hallucination detection.
