I am a professional with 4 years of experience in software development.My responsibilities include proposing technical solutions focused on Cloud environments. Additionally, I have experience in identifying technical debt and evolving technology stacks in legacy systems. I have worked with cutting-edge platforms such as .NET, Lambdas, DynamoDB, and API Gateway, and have experience with agile development methodologies.Currently, my main focus is on developing scalable backend applications capable of handling increased user load, workload, and demand. To achieve this, I apply SOLID principles, ensuring code modularity, flexibility, and maintainability.I place a high value on unit testing, as it ensures code quality and reliability. Additionally, I consider mutation testing essential, which involves intentionally altering the code to verify whether unit tests effectively detect potential failures.Integration testing is also crucial to me, as it ensures that different system components work correctly together, preventing regressions and errors that could re-enter the development backlog.My goal is to build robust, well-tested backend applications that are ready to tackle scalability challenges and growing demands.
