What I'm looking for

I’m looking for opportunities in AI, Data Science, and Machine Learning where I can build and deploy practical data/ML solutions. I want to apply hands-on experience in NLP and computer vision, collaborate across cross-functional teams, and deliver results efficiently.

I’m a Big Data & Artificial Intelligence engineer focused on turning data into reliable, production-ready AI capabilities. I’ve built end-to-end multilingual speech processing systems combining STT, TTS, translation, and summarization, including fine-tuning Whisper Large V3 for Tunisian Arabic and integrating XTTS v2 for multilingual voice synthesis.

Across my internships, I’ve centralized KPIs and shipped analytics dashboards, performed large-scale scraping and NLP preprocessing, and optimized models for sentiment analysis and text classification. I bring a hands-on, results-driven approach to data wrangling, feature engineering, and predictive modeling—supported by tools like Python, FastAPI, Hugging Face, and PyTorch, and backed by projects in YOLO/Faster R-CNN/SSD and image captioning with Vision Transformers and GPT-2.
