At Banco Internacional, I designed and implemented an institutional cafeteria automation system spanning a vendor app, HR order and payment management, electronic payments, and a web portal. I built the solution with React, C# (.NET), and SQL Server.

I also designed SSIS pipelines for asynchronous third-party REST APIs and administer the institution's SSRS and SSIS reporting ecosystem. Previously, I developed analytics dashboards and a PLC-integrated packaging control system at Colgate-Palmolive, and built inventory and academic platforms as a freelance developer.
