What I'm looking for

Looking for remote .NET/C# developer and SQL Server DBA roles, hireable from Mexico. Fintech and payments companies welcome.

At Boz IT, I develop and maintain REST APIs and a Web Forms monolith for a fintech lending platform. I’m leading its modernization from .NET Framework to modern .NET, with services supporting loan origination, collections, bank reconciliation, and AML compliance.

I also work as a Database Administrator for Intermex, administering SQL Server databases across Always On availability groups. I implemented Transparent Data Encryption, improved compliance and wire transfer procedures, and designed incremental data extraction for large tables.

Previously, I administered production databases for La Nacional and built retail point-of-sale applications at Boz IT for Soriana and La Nacional. My work has also included migrating systems to Azure and GCP, integrating external services, and building CI/CD pipelines.
