Freelance · P.IVA
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.
