What I'm looking for

I'm interested in applying my chemical engineering domain knowledge to AI evaluation, data annotation, and model-output assessment.

At Kaliti Food Share Company (Cerealia), I monitored food-manufacturing processes from raw-material handling through packaging and analyzed process parameters, equipment performance, and production flow.

As an Undergraduate Researcher in Chemical Engineering, I studied ultrasound-assisted extraction of betalain pigment from red beetroot. I designed and analyzed experiments on citric acid concentration and ultrasonic power, using Design-Expert for experimental design and optimization.

I prepare structured technical research documentation and work with laboratory analysis, process evaluation, and quality control. I'm interested in applying my chemical engineering knowledge to AI evaluation, data annotation, and model-output assessment.
