What I'm looking for

I'm available for remote roles and contract work.

At Loopstudio, I split Kalibri’s hospitality-analytics monolith into four independently deployable Spring Boot services and standardized their Gradle builds. I also moved authentication to Auth0, replacing custom credential handling with OAuth 2.0 flows.

For DataArt, I rebuilt Java marketing-reporting jobs in Python on Google Dataproc and orchestrated them with Airflow, cutting runtime from over 12 hours to 30 minutes. I also built flight-booking features for Priceline and maintained services for Bebbia.

Earlier, at Pyxis, I designed and deployed a system-administration application for a multi-tenant IoT platform and implemented Spring Boot device services integrated with Kafka and FIWARE. I’ve also built payment-gateway features at Verifone and Java Enterprise applications at Antel; I work daily with Claude Code, the Anthropic API and Cursor.
