Sobre mí

I'm a Senior C#/.NET Developer with 10+ years of experience helping companies modernize legacy systems, build scalable backend services, and solve complex technical problems.

My strongest skill is quickly understanding unfamiliar codebases and turning difficult, high-risk projects into maintainable, production-ready solutions. Whether it's a legacy application that nobody wants to touch, a performance bottleneck slowing down the business, or a critical integration blocking delivery, I focus on solving the problem rather than simply writing code.

Over the years I've worked on:

• Legacy system modernization and large-scale refactoring • REST and SOAP API development and integration • ASP.NET Core backend services • Microservice architectures • RabbitMQ and asynchronous processing • WinForms, WPF, and WinUI desktop applications • Performance optimization and troubleshooting • Complex bug investigation and resolution • Enterprise software development
