Ruben Martinez Tanahara
Senior Software Engineer · .NET & Azure
Software Engineer with 4+ years building .NET and Azure systems. Currently working as a Senior Consultant at Apex Systems.
My background spans backend services with C#/.NET Core, cloud infrastructure on Azure, and full-stack work across TypeScript, React, and mobile (Flutter, React Native). I've worked on ERP systems, warehouse management, mortgage CRMs, and e-commerce apps across multiple industries.
I care about writing code that is readable, tested, and maintainable — not just code that works today.
