Experience

AI Engineer

FersmithAI

Architecting FersmithAI, an innovative learning ecosystem that transforms dense technical engineering resources into personalized, adaptive audio-learning experiences and smart summaries. Engineered SkyAnalyst-AI, a modular cabin operations intelligence framework powered by RAG, ChromaDB vector storage, and DistilBART-CNN to convert unstructured flight logs into structured insights with 4x faster inference. Developed Children’s Tale Summarizer, a complete NLP pipeline and Flask application that benchmarks 15+ transformer models (optimizing ROUGE-L from 0.25 to 0.52) for segmenting Turkish stories and generating AI illustrations via Stable Diffusion.

SkyAnalyst-AI: Cabin Operations Intelligence Framework
A modular NLP framework that transforms unstructured flight cabin reports into structured operational insights using RAG and abstractive summarization. Built on ChromaDB vector storage and all-MiniLM-L6-v2 embeddings for semantic retrieval across 2,500+ synthetic incident reports — enabling meaning-based search that goes beyond keyword matching. Summarization is powered by DistilBART-CNN, delivering 4x faster inference than standard BART with negligible quality loss. Includes an exploratory analytics dashboard with sentiment intensity scoring and statistical visualizations across 5 incident categories and 22 flight routes.
