Jefferson Montesdeoca Jordan

Solutions Architect at Andbank designing Java banking systems and leading a 40+ VM platform migration.

What I'm looking for

I'm selectively open to relevant opportunities in Andorra, Spain, or remotely across European time zones.

At Andbank, I design backend architecture for private banking with Java 21 and Spring Boot 3, and lead the migration from Spring Boot 2 to 3 and Tomcat 7/8 to 9/10 across 40+ VMs.

I integrate legacy COBOL, AS400, and DB2 systems, and rolled out Gemini Code Assist for the team as the department’s first AI adoption. I also manage technical vendors and build-vs-buy decisions.

My work has spanned legal marketplaces, Vodafone microservices, and energy-sector Big Data. Alongside that work, I build live and in-development products, including Transolido, a VERI*FACTU-compliant invoicing product with AI-assisted data extraction.
