About
The person behind the code
I started coding at 14 and never stopped. Today, with 19+ years of experience, I work as a fullstack engineer with real depth across backend, frontend, mobile and — increasingly — applied artificial intelligence.
I've led and shipped dozens of products: multi-tenant SaaS and ERP platforms, native and cross-platform mobile apps, industrial telemetry systems and AI platforms running in production for thousands of users.
I enjoy solving hard problems with the right tool, writing software that lasts and learning continuously — especially at the frontier of generative AI.
How I work
- From prototype to deploy
- Systems that scale
- AI applied for real
- Continuous learning
Artificial Intelligence
Applied AI engineering, from prototype to production
I design and ship systems with RAG (retrieval-augmented generation), autonomous agents, document ingestion and structuring, embeddings and vector databases, automations and real-time voice interfaces — always focused on reliability, cost and scale. I've delivered AI platforms used daily by thousands of people.
