AI Systems Engineer
Building production-grade LLM, RAG, and multi-agent systems for clinical, legal, and enterprise workflows.
"Don't get distracted by a young developer's age. Building digital products from scratch, scaling them, and finding product-market fit is by far the hardest job I've done. But having a team member like Santi makes it so much easier."

Don't get distracted by a young developer's age. Building digital products from scratch, scaling them, and finding product-market fit is by far the hardest job I've done. But having a team member like Santi makes it so much easier. He's one of the best developers I've known — not just for his technical skills, but for his personality, discipline, and enthusiasm.
