At Infomarcas, I developed web solutions with C#, .NET, and Blazor, including a library of more than 30 reusable UI components that reduced delivery time for new features by 10%. I also implemented .NET Core APIs integrated with external services and automated a pipeline sending 2,000 messages a day through the WhatsApp Business API.
At Sum Software, I refactored legacy code and optimized SQL queries, reducing average database response time by 15% and error rates by 30%. Earlier, at ProfPlay, I developed full-stack web systems and created APIs with PHP and Laravel.
