Felix Koech

I’m an AI Trainer, Data Annotator, and Web Developer with 2+ years of freelance experience delivering AI training and data work for global clients. My focus is on strengthening model outputs with careful data annotation, dataset curation, and LLM evaluation.

I specialize in RLHF tasks such as ranking AI responses and prompt evaluation, then providing human feedback to improve model behavior. I also fine-tune language models and keep data quality high through strict guideline adherence, content moderation, and quality assurance.

Alongside AI work, I design and build responsive websites and WordPress sites using HTML, CSS, and Elementor. I’ve also executed SEO and PPC campaigns using Google Ads and Google Analytics to improve traffic and conversions.

I take pride in consistently delivering results—maintaining a 95 percent on-time project delivery rate with clear communication and client satisfaction. I enjoy research, fact checking, and prompt engineering because they directly translate into better datasets and better model performance.
