Description

Senior Consultant Analyst / Software Developer | C# .NET (Back-end)

Senior consultant with over 20 years of experience in software development, specializing in C# / .NET back-end solutions.

I am involved in the design, development, and evolution of robust and scalable applications, mainly in web and API-oriented environments. My role covers the entire application lifecycle: needs analysis, technical design, development, cloud deployment, maintenance, and improvement of existing systems. I work on both monolithic and microservices architectures, as well as migrating legacy applications to modern, scalable solutions.

I am bilingual in Portuguese and French, which has allowed me to work on projects for French-speaking clients in international contexts since 2011. I have worked in national contexts in Portugal and internationally, particularly in France, both on-site and full-remote.

Accustomed to agile and collaborative environments, I easily integrate into multidisciplinary teams or work autonomously. If the client requires full-stack skills, I am also proficient in Angular development.

My expertise is strongly oriented towards C# / .NET back-end, with a particular focus on code quality, performance, and reliability of the developed solutions.

Skills :

C#, .NET, ASP.NET Core, Web API, REST, Microservices, SQL Server, Entity Framework, TDD, Backend Development, Clean Architecture / Onion, Agile, Grafana, RabbitMQ, ElasticSearch, Prometheus, Redis Cache, AWS, Azure DevOps, GitLab, CQRS, DevExtreme, Angular, NgRx Store
