Good — let me give you what actually matters.

I'm an AI Engineer and Senior Full Stack Developer with 15+ years shipping web, mobile, banking, education, and AI systems. Recent work: AI Solutions Architect at Nivelics and AI Engineer at Cambio Colombia (CrewAI, Mastra, MCP, RAG).

85% faster delivery — led the SaaS team at Validation Solutions Banking cores + mobile apps at Intercom Tecnología EVOZ educational app — Apps.co UNAB awards (1st Santander) Systems Engineer — CUN University (2018–2024) Available for remote work worldwide

Tell me what you're building — I'll tell you if and how I can help.

My background is production AI and full-stack systems: LLM workflows with CrewAI and Mastra, MCP tooling, RAG pipelines, NestJS/Node backends, and multi-language delivery across web and mobile.

I've shipped systems that had to be right, not just impressive — banking security, SaaS platforms, and AI-driven data processing. If your problem has those kinds of stakes, that's exactly my context.

Right now I'm deepening multi-agent systems and production LLM workflows — not chasing demos.

CrewAI & Mastra-AI — agent orchestration in real client work MCP & A2A — tool protocols and agent-to-agent patterns RAG — retrieval grounded in heterogeneous data Continuous learning — practical problem-solving and mentoring

Recent roles at Nivelics and Cambio Colombia put these stacks into AI solutions and data platforms. Ask me what you're building and I'll connect the dots.
