@sergioledesma
Software developer specializing in backend, full-stack systems, resilient APIs, and automated testing.
ArgentinaWhat I'm looking for
I build and improve production systems end-to-end—starting with complex relational databases and automation scripting, and extending through modern APIs and automated testing.
I’m especially focused on Backend and Full-Stack development, delivering system creation, refactoring, and maintenance with resilient architectures for international clients and enterprise projects.
In recent freelance work, I developed and refactored APIs using Next.js, TypeScript, and Prisma ORM, implemented resiliency systems and workers, and created comprehensive unit and integration test suites with Vitest integrated into CI/CD via GitHub Actions.
Earlier, I developed corporate management features with PowerBuilder and strengthened business logic through advanced database administration and design in Sybase SQL using Stored Procedures and Triggers.
