What I'm looking for

I seek senior leadership roles where I can scale engineering teams, set technical strategy, and drive AI-enhanced product innovation in fintech/payments with autonomy to build high-performance cultures and measurable impact.

I am a senior engineering executive with a track record of scaling fintech engineering organizations and delivering high-impact products. I specialize in technical strategy, team building, and AI-enabled product innovation.

At Stori I built an Argentina tech hub from 10 to 93 engineers in 18 months and launched an onboarding system that generated 135K deposit accounts in one month. I improved credit conversion speed by 45% and cut mobile feature delivery from weeks to days through modular architecture.

Previously I led payments platforms at Konfío and launched Brazil's first payroll product at Mercado Pago, delivering systems that handled hundreds of thousands of RPM and hundreds of terabytes of storage. I drove migrations from monoliths to microservices, improved availability, reduced response times, and achieved PCI compliance.

I now focus on integrating LLMs, RAG and AI agents to accelerate engineering delivery and automate workflows. I enjoy mentoring leaders, building high-accountability cultures, and aligning technical roadmaps to measurable business outcomes.
