.NET Developer at SACYR who developed an employee performance review tool and contributed to a large-scale website.

Spain
Message

At SACYR, I developed an internal tool to automate and centralise employee performance reviews, replacing a manual workflow based on Excel spreadsheets. I also recently worked with a team of 20+ developers on a large-scale website using .NET 10, integrating Microsoft Copilot into the engineering workflow and gaining hands-on exposure to Azure cloud services.

Across freelance projects in insurance, advertising, digital marketing and construction, I’ve built and maintained web applications, including AXA Global Direct’s payment gateway replacement and authentication migration. My work has included ASP.NET, SQL Server and API development, as well as collaboration with remote teams in Agile environments.
