What I'm looking for

I'm looking for opportunities to build production AI or full-stack products, work with modern NLP and LLM systems, and contribute to scalable, user-focused software in collaborative Agile teams.

At Pi School, I built an Italian-language voicebot intent classification and discovery system that improved automation accuracy from 34% to 90% using fine-tuned BERT, NLP, and calibrated confidence routing.

I've also delivered ASP.NET Core and Angular applications at SDSol Technologies and OakStreet Technologies, including secure APIs, RBAC, payment integrations, SQL optimization, and LLM-powered user assistance. I combine full-stack engineering with machine learning work in recommendation systems, predictive analytics, and conversational AI.
