Hi, I'm Alexis Ocando
Backend and Embedded Systems Developer
I'm a backend developer with a strong focus on C# and .NET ecosystem, and I take architecture seriously. My experience ranges from designing scalable cloud APIs on Azure to integrating systems with physical hardware. Code quality isn’t just a buzzword for me; I stick to SOLID principles and Clean Architecture because maintainability is non-negotiable.
Professional Experience
Software Developer
Mundos Virtuales SPA
- • Architected and developed a scalable backend using ASP.NET Core Web API and C#, deployed on MicrosoftAzure, to handle transactional data securely and reliably, following SOLID, Domain-Driven Design (DDD), and Clean Architecture principles.
- • Implemented an automated regional technical support system using .NET and Semantic Kernel, enabling field technicians to interact with an AI assistant (RAG) trained on complex technical manuals, reducing manualsupport tickets by 60%.
- • Designed and implemented an internal monitoring and diagnostics system via REST Web Services, providingreal-time visibility and proactive fault detection for connected devices.
- • Built a complete banknote counting solution using C# Windows Forms, including user authentication, analytics dashboard, and counting interface, integrating a Giesecke+Devrient validator and proprietary control board.
- • Modernized a legacy app by refactoring its Python codebase and upgrading the UI to PyQt6, improving maintainability and integration with UW-F Series banknote sorting machines.
