Senior Software Engineer · Oracle ACE Associate · Java & AI Speaker
Java, AI, and mission-critical systems. Based in the Dominican Republic 🇩🇴
Senior Software Engineer with 6+ years building systems that can't afford to go down. Banking platforms, high-traffic mobile apps, and middleware that moves real money and real data at scale. I have a Master's in Data Science (UCJC) and a Telematics Engineering degree (PUCMM), and that combination has pushed most of my work and thinking toward the intersection of backend engineering and AI.
Beyond shipping production software, I do sometimes teach at PUCMM, speak at conferences: JConfDominicana, DevNexus, Azul Systems AI4J, and Java User Groups across the globe — and help organize JConfDominicana every year. I co-lead the Dominican Republic Java User Group, and have been featured in Open Source Global Voices as a Caribbean technology contributor. When time allows, I contribute to open source.
Most of my experience comes from working on systems with real operational weight. A few examples:
- Banking core systems. Backend work on high-volume platforms processing millions of transactions weekly. The job is keeping them correct and stable, not just functional.
- Mobile app for the DR's largest telecom. Backend engineering for an app with around 1 million users. Performance issues here are not abstract.
- Email middleware at scale. Led the architecture and full implementation of a cloud-native system on Java and AWS that handles 250M+ emails per year for a global healthcare data company.
- Spring Boot 2 to 3 migration. Led this on a live production platform. The goal was security and performance. The constraint was keeping everything running while doing it.
- Enterprise SaaS integrations. ERP, CRM, and third-party integrations across multiple industries using enterprise integration patterns, microservices, and event-driven designs.
Working on these has made me good at debugging things that aren't supposed to break. Tracing slow queries, tracking down race conditions, reading production logs at odd hours. That's where a lot of the real learning happens.

I talk about things I've actually worked on.
| Event | Talk |
|---|---|
| DevNexus 2026 · AI4J Conference · JConfDominicana 2026 | "OK, But What About Predictive AI?" |
| JConfDominicana 2025 | "Optimizing LLM Responses with RAG in Java" |
| JConfDominicana 2024 | "Hablando de basura: Garbage Collector, ¿Qué es? ¿Cómo funciona? ¿Cuál debería utilizar en mi aplicación?" |
| Java User Groups (multiple) | Java in Education, AI/ML in the JVM |
The IT Dojo is where Sensei Rafa and I write about the things that don't fit in a Stack Overflow answer. Production debugging sessions, architectural decisions made under real constraints, and the full arc of designing, building, and shipping systems that actually create value.
No tutorials for tutorials' sake. Just honest accounts from people who've had to answer for the systems they've help built.

Available for:
- Speaking at your user group or conference — I talk about things I've actually built. Java, AI on the JVM, Predictive vs. Generative AI, RAG, and production engineering. If any of that fits your audience, let's talk.
- Consultancy — If you have a project where you think my experience in Java, backend systems, or AI/ML integration can bring value, I'm open to the conversation.
Open to collaborations and honest conversations about Java, AI, and engineering in Latin America.
