Full Stack Developer and Mechatronics Engineer with hands-on experience building production-ready web applications and end-to-end IoT systems. I specialize in backend architecture with .NET Core and C#, RESTful API design, and integrating embedded systems (ESP32/Arduino) with cloud platforms using MQTT and real-time protocols.
I build complete systems — from firmware and hardware to backend APIs and frontend interfaces — with a focus on Clean Architecture, SOLID principles, and scalability.
Currently open to remote full-time or contract opportunities in backend, full stack, or IoT engineering.
EcfDgi.Client_C_Plus_Plus - EcfDgii.Client API & SDK — Dominican Republic Electronic Invoicing (C++)
EcfDgii.Client is an enterprise-grade C++ solution that wraps and exposes the Dominican Republic Tax Authority's (DGII) Comprobante Fiscal Electrónico (e-CF) REST integration services. Built under Clean Architecture and Domain-Driven Design (DDD) principles, it provides a robust REST API, secure JWT-based authentication, PostgreSQL persistence with automated auditing and soft-delete, request validation rules, structured logging, and full Docker orchestration support.
