Staff Engineer at Leo Vegas shaping distributed systems and engineering standards across platforms.

At Leo Vegas, I work across platforms to support engineering best practices, architectural consistency, and long-term maintainability. I help teams design and evolve distributed systems, review implementations, and contribute to technical standards.

At Alter Solutions, I led the LADR government system for worldwide aviation, working with Java microservices, REST and GraphQL, and Azure services. I also represented technical topics in security and architecture forums and coordinated team follow-up.

Across financial, banking, insurance, healthcare, and public-sector systems, I’ve worked through the software development lifecycle and built enterprise applications with Java. At Zoop, I managed 31 developers across two squads working on transaction APIs for banking-as-a-service payments.
