Freelancer Overview

Analytical Full-Stack Developer specializing in high-fidelity code generation QA, RLHF preference tuning, and adversarial red-teaming for Large Language Models. Proven track record of evaluating complex multi-file repositories, detecting edge-case logical fallacies, and diagnosing memory leaks across JavaScript/TypeScript (React, Node.js), Java (Spring Boot), and Python environments. My approach to data annotation is strictly evidence-based: I provide granular, step-by-step justifications for response rankings, verifying code compilation, syntax accuracy, and algorithmic efficiency against strict rubric constraints. Experienced with industry-standard annotation workflows and third-party labelling tools (including Label box and CVAT). Available for high-complexity technical tracks requiring extreme attention to detail and deterministic accuracy.
