About Luis Miguel

¿Tu arquitectura actual frena el crecimiento de tu negocio? Ayudo a empresas y startups tecnológicas a transformar sistemas heredados (legacy) en arquitecturas modernas, escalables y eficientes en la nube. No solo escribo código; diseño soluciones que reducen la deuda técnica y preparan tu infraestructura para escalar.

Cómo puedo ayudarte: Con más de 5 años de experiencia como Lead Software Engineer, aporto una visión híbrida única: la solidez arquitectónica de .NET (C#) combinada con la agilidad de Python para la ingeniería de datos. Mi enfoque es pragmático: código limpio, infraestructura robusta y automatización total.
