I built CarValue, an end-to-end used-car valuation model trained on 8,400 vehicle records. The model achieved an R² score of 0.970 and was deployed as a web application for generating vehicle price estimates.

I handle data preprocessing, feature engineering, model training, and performance evaluation to turn predictive concepts into functional applications.

As a freelance Prompt Engineer, I designed structured prompts for reasoning, classification, extraction, summarization, and content generation. I evaluated LLM outputs, identified failure patterns, and created reusable prompt templates to improve accuracy, consistency, and instruction adherence.

I also built TripsForge, a responsive travel planning platform for destination discovery, itinerary creation, and trip organization, using Supabase-backed data management.
