AI & Software Engineer
building real things with LLMs.
I help companies and startups ship production-grade AI features — NLP pipelines, RAG systems, LLM integrations and the backend that makes them work in the real world.
Services
What I can build for you
📚
RAG Systems
End-to-end Retrieval-Augmented Generation pipelines — ingestion, chunking, embeddings, vector DBs and answer evaluation.
⚙️
Backend & APIs
Production-ready Python and Java backends. FastAPI services, PostgreSQL, Docker deployments — built lean, no over-engineering.
🔁
AI Automation (n8n)
Workflow automation for SMEs combining n8n, LLMs and external APIs. Replace repetitive ops work with reliable pipelines.
📊
ML Engineering
Custom models for classification, time-series and computer vision. From dataset cleaning to deployment, with proper evaluation.
🧪
Technical Consulting
Code reviews, architecture audits, AI-readiness assessments. Honest feedback on what to build, what to buy and what to drop.

About
Hi, I'm Devis 👋🏼
I'm a Computer Science master's student at Politecnico di Milano, specialising in AI/ML, NLP and Edge AI. Alongside my studies I work as a freelance AI & Software Engineer, helping companies turn LLM ideas into production systems that actually ship.
My background blends academic depth (3.7/4.0 GPA, 4 lodi) with hands-on engineering experience: I spent 7 months at Sensei Srl building an applicant tracking system backend with Java Spring Boot, Apache Lucene and PostgreSQL — full-text search, CV processing, real production constraints.
I work best on lean, well-scoped projects where outcomes matter more than buzzwords. If that sounds like you, let's talk.
