At Ethara AI, I contribute to LLM training and evaluation through RLHF, curating and annotating human preference data. I benchmark model responses with structured rubrics and analyze failure cases to inform fine-tuning priorities.
I also optimize OpenClaw outputs through prompt optimization and iterative evaluation, reducing unnecessary token consumption while preserving answer quality and completeness.
As a freelance full-stack developer, I managed client projects from requirements and UI/UX design through development, testing, and deployment. I built responsive applications with React.js and Next.js, and backend services with Node.js, Express.js, MongoDB, and PostgreSQL.
I built Pro Talent Connect, a live talent discovery platform with four user roles and more than 50 REST API endpoints. I also developed a bilingual grocery storefront and a payroll system, applying authentication, database optimization, and responsive interface design.
