(About)

About me

.NET engineer with solid experience building scalable, high-performance web systems for logistics, transportation, and corporate environments. Specialist in C#, ASP.NET Core, Blazor, MVC/Razor Pages, and SQL Server (jobs, procedures). Experience with Git, API development, dashboards, and background processes handling thousands of daily requests with reliability and clean architecture.

I currently work on systems with 5 to 20 thousand daily accesses, including API integration for mobile apps (Flutter), internal vehicle movement control systems, and automation pipelines with C# processes. I have strong experience in legacy system modernization, database migration, system integration, and performance-oriented SQL. I was responsible for API and EDI integrations at Transmoreno, Renault's main logistics partner.

Beyond development, I have a constant interest in information security and participate in Open Bug Bounty. I enjoy studying software architecture, data protection, and best practices, and I keep a habit of technical reading — from programming and architecture books to topics like Linux and cyber threats.
