Hello there,
I am a Java/Go architect/developer with over 19 years of experience, with core domain expertise in fintech/banking, e-commerce, and blockchain/cryptocurrencies.
In the last eight years I have architected two large distributed software systems, one for a universal bank and another for a government financial institution, which took three and two years to complete, respectively. In these two projects I have had the opportunity to architect to the interfaces/APIs of a core banking system, data warehouse, ETL system, SAP ERP, plus some other external systems like LDAP and SOA middleware like Oracle Service Bus (OSB). I also have experience integrating with EDI systems.
For the universal bank I have additionally migrated a 17-year-old Oracle database to IBM DB2.
