I've built enterprise and retail software at Actinver, KidZania, Farmacias del Ahorro, BR Taepi, and SAI Castillo Consultores. My work spans C#/.NET applications, RESTful APIs, SQL Server databases, Azure SQL maintenance, reporting, and production support.

I’ve developed POS synchronization APIs, a warehouse management system, and a turnstile access-control desktop application. I focus on maintainable layered architectures, SOLID principles, reliable deployments, and translating operational requirements into practical software.
