About

Full-stack software engineer focused on production-ready systems.

I am a full-stack software engineer who develops enterprise solutions and end-to-end web and mobile applications. I work across the stack, building frontend experiences in React/Next.js, implementing backend services with NodeJS/Express and Rust (Axum), and designing the infrastructure that keeps systems reliable and secure.

I currently work as Lead Fullstack Software Engineer at Manuel S. Enverga University Foundation - Candelaria Inc. I also serve as a Lead Software Engineer on a part-time contractual basis at R-A-Ones Corporation in Canada, and lead a freelance group delivering software solutions for clients worldwide. I coordinate teams, own delivery, and translate product goals into pragmatic technical solutions.

Recently, I’ve been exploring AI and cloud infrastructure—focusing on agentic workflows, model orchestration, and scalable architectures to bring AI into production effectively.
