Building Digital Experiences. Evaluating the Intelligence Behind Them.
I'm BEN JAHSON TOJAH, a Full-Stack Web Developer and AI Training & Evaluation Professional. I build websites and digital solutions for businesses while contributing to the development and evaluation of intelligent AI systems.
01 — About
Useful products, carefully made.
BJT
I build modern, responsive digital experiences that help businesses establish their online presence and operate more effectively. I care about products that are useful, accessible, and quietly well designed — the kind people can use without thinking about it.
Alongside software development, I contribute to AI training and evaluation workflows, helping improve the quality, accuracy, and usefulness of AI-generated outputs. Reviewing how models respond has sharpened how I think about clarity, correctness, and the people on the other side of the screen.
The two disciplines inform each other: building teaches me what good output looks like in practice, and evaluating teaches me to question it carefully.

04 — AI Training & Evaluation
Working With AI. Improving What Comes Next.
Through project-based work on AI training and evaluation platforms, including Outlier and Handshake, I review and assess model outputs against detailed guidelines. The work is careful and methodical: reading closely, judging fairly, and writing feedback that helps models become more accurate and more useful.
