## PLEASE CONTACT ME TO DISCUSS THE DETAILS OF YOUR PROJECT ## I'm a seasoned software engineer passionate about hands-on coding with best practices and clean code in mind for the best results. I apply software craftsmanship that prioritizes building maintainable, scalable, extensible, reusable, testable, and performant solutions, praising the longevity of a product while keeping it cost-effective and efficient in the long run. "Clean code always looks like it was written by someone who cares." -- Robert C. Martin A brief insight into what I bring to the table: - Design and implementation of backend solutions, including microservices and serverless in Microsoft Azure; - Hands-on engineering on .NET stack with DDD and TDD, including Clean Architecture and CQRS; - Emphasis on best practices and principles, such as SOLID, DRY, YAGNI, KISS, Clean Code, and Design Patterns; - Team leadership with mentoring and coaching on Agile, best practices and principles, methodologies, systems design and communication; - Autonomous delivery of high-quality bespoke solutions that prioritize the main "-ilities" of software. # EXPERTISE Backend: .NET Framework, .NET Core, .NET 5/6/7/8, C# Frontend: ASP.NET MVC, HTMC5, CSS, Angular, React, Typescript Services: ASP.NET WebAPI, gRPC, JSON, Entity Framework, Hangfire Architecture: Clean, MSA, Monolithic, CQRS, Mediatr, Messaging, SOA Cloud: Serverless, Microsoft Azure, Docker, Kubernetes, Keyvault Testing: Unit Testing, Integration/Acceptance Testing, TDD, xUnit Quality: OOP/OOD, SOLID, DRY, YAGNI, KISS, Design Patterns, Clean Code Database: SQL Server, T-SQL, NoSQL (MongoDB, Azure Cosmos DB) Methodologies: DDD, Agile, SAFe, Scrum, Kanban, Scrumban Other: VB, VBA, Python, Node, AOP, Git, Jenkins, Jira, Azure DevOps # RECOMMENDATIONS "There are few people who can tackle complex tasks independently with minimal information, and Alex is one of them. When working on specialized operations, there’s often limited space for involvement, but Alex consistently steps up. With his deep expertise, vast knowledge, and mastery of software principles and patterns, he will undoubtedly strengthen any team he joins. I highly recommend Alex for his backend expertise and the great experience of working with him." -- Avdo Husic "Alexandre's uncompromising attitude and passion to create a high-quality product was effective in every step of the development process." -- Kobi Hagmi "Always willing to do his hard work and invest on the company, rather than simply working for it." -- Felippe Rangel "We worked together for several months for a dutch client, and Alexandre displayed solid skills in .NET development." -- Fabio Correia "I have worked with Alexandre for several months in a high complexity and demanding project, which he performed with excellence. He has proven his expertise in .NET and related technologies/methodologies, such as C#, VB.NET, Design Patterns, Clean Code practices and DDD." -- Denys Gavriushenko
