At Caristeo Tecnologia, I contributed to a multi-tenant content marketing SaaS platform, delivering modules from data model to user interface. I also built a multi-agent AI content generation pipeline with provider fallbacks, structured output retries, and automated image quality evaluation. I integrated LinkedIn and Instagram publishing through OAuth 2.0 and developed an editorial calendar with scheduled jobs, retries, and time zone support. I evolved the PostgreSQL data model with Prisma migrations, data migration scripts, and preflight audits. I also implemented role- and company-based authorization and built a Jest, ts-jest, and Supertest suite with 440+ cases. At Goyan Developers, I designed RESTful APIs with PHP and Laravel and worked on PostgreSQL and MySQL schemas. I also implemented Redis caching and structured backend applications using Clean Architecture.
