What I'm looking for

I want to lead architecture and delivery for high-availability, high-transaction systems—combining backend depth with full-stack execution. I’m looking for a team where I can drive modernization, automation, and technical leadership while continuing to grow into new tooling.

I’m a senior software engineer with 7+ years of experience in freelancing and corporate projects, with a constant drive to adopt new technologies. I’m especially strong in Java and Node.js backend development on JBoss and Wildfly, building reliable systems backed by MongoDB/MariaDB.

As CTO at Lucky Intelligence (2017—2023), I led technology decision-making and architecture, server administration, cloud architecture, and deploy systems, while managing the dev team and guiding full-stack and mobile development. At Grupo Salinas (2017—Present), I’ve owned high-criticality, high-availability projects and high-transactional backend development at scale, including C++ DLL/shared library work, migrations/refactoring, and bot + web scraping pipelines—while deepening my knowledge in Rust for utilities and tooling.
