What I'm looking for

I’m looking for a .NET full-stack role where I can build web and desktop apps, design and consume APIs, and deliver reliable features with tests in agile teams—using Azure services and modern tooling to optimize performance.

I’m a .NET Developer focused on full-stack delivery, building efficient web and desktop applications with Angular, React, and modern ASP.NET approaches. I care about clean architecture, performance optimization, and reliable, maintainable code.

In my recent role at Emergn (2025 – Today), I design and develop full-stack web applications from scratch—building and consuming web APIs, managing database migrations with EF code first, and supporting deployments through pipelines. I contribute to code reviews, unit and automation testing, and Scrum collaboration, and I use GitHub Copilot to improve productivity and code quality.

Previously at Marsh McLennan (2023 – 2024), I developed and maintained web applications and microservices, worked with state management (NGRX), and continued API and pipeline-based delivery. I’ve also built and styled full-stack UIs, retrieved data with Entity Framework, and delivered APIs end-to-end in projects like Nearshore Portugal (2022 – 2023).

Earlier at Altran/Capgemini (2019 – 2021), I helped replace legacy UI with high-performance solutions for large databases and developed desktop and web applications using WPF/WinForms, MVVM/Prism, and Entity Framework. I’ve consistently combined application development with strong database and query skills to ship fixes, new features, and integrations.
