Senior Full Stack Engineer, Tech Lead, and AI Architect with 10+ years building enterprise systems for banks, financial cooperatives, and public-sector clients across LATAM. I care about regulatory-grade reliability, pragmatic modernization, and code that still makes sense five years from now.

Currently Development Supervisor & AI Architect at SEA Servicios Múltiples (Costa Rica), architecting an automated document-capture platform (IDP/ADE) on .NET 10 with self-hosted vision-language-model inference on private GPU infrastructure — designed AI-first but not AI-authoritative: deterministic validation, explicit abstention, and full traceability stay in authority over every published value.

🇨🇷 Costa Rican national · 📍 Mexico City (GMT-6 year-round) · 💻 100% remote

• AI architecture in production — self-hosted VLM serving (Ollama on AWS GPU), per-invocation inference telemetry, content-hash caching and quality gates that resolve ~40% of requests without invoking the model, and model-replacement evaluation against verified ground truth.
• Document-centric automation with OnBase (Hyland Certified Workflow Engineer) — credit-origination workflows for two of Costa Rica's largest financial cooperatives, Factura Electrónica 4.0 compliance, and integration with BCCR national digital-signature infrastructure.
• Legacy modernization on .NET and Java stacks — from stuck-on-WebSphere monoliths to current, secure, supported platforms (most recently at Scotiabank, 2022–2025).
• Tech leadership — code-review standards, Definition of Done, mentoring, and the right architectural trade-offs under regulatory constraints.
