About Guglielmo
I design and build secure digital infrastructure, then automate it with AI.
I help companies solve the problems their current team can't: security vulnerabilities in production SaaS platforms, complex system migrations, AI integration into existing workflows, and full-stack architectures that need to scale without breaking.
What I deliver: security audits that reduce your attack surface from critical to hardened. AI pipelines that replace manual processes with deterministic automation. Production-grade web platforms built solo from database schema to deployed frontend.
Core stack: React, TypeScript, Python, Node.js, PostgreSQL, Supabase, Docker, Linux. Security: OAuth 2.0 (PKCE), Row-Level Security, penetration testing, SOC-2 aligned practices. AI: LLM orchestration, RAG pipelines, autonomous agent systems.
Track record: 120K+ user platforms, $15M FinTech infrastructure, SaaS security risk reduced from 8/10 to 2/10, 51K LOC AI governance engine, custom OAuth 2.0 Identity Provider built from zero.
