What I'm looking for

I’m seeking to design and develop technology solutions that optimize business operations, contributing technical rigor, sound judgment, and practical outcomes that create value for the organization.

At Tallanes Packers S.A.C, I maintained inventory and logistics systems, recreated a traceability system, and created a costing system for the traceability area.

I also developed an MVP for a financial system covering costs, budgets, and cash flow, using MySQL, PostgreSQL, Laravel, Nest.js, React, Vue, TypeScript, JavaScript, PHP, and Python.

At Valle San Miguel S.A.C, I developed an agricultural traceability system comprising a mobile app and web dashboard, as well as financial systems. I documented the work and carried out unit, integration, and end-to-end tests.

Earlier, as a Junior Programmer on the Health Project, I maintained and improved a clinic system, including multi-tenant functionality and automated WhatsApp appointment reminders. During my internship at Inmobiliaria y Constructora KTM S.A.C, I worked on a landing page and desktop system, including SQL Server data modeling, C# modules, reports, and production deployment.
