.NET Back-End developer with 4 years building distributed systems end-to-end: microservices, physical hardware integration, biometrics, cameras, alarms, AI, messaging and real-time distribution.
I work with .NET microservices architecture and data modeling using relational and NoSQL databases (SQL Server, MySQL, PostgreSQL, MongoDB, Redis) — 15+ services designed and running in production.
Responsible for integrating and homologating equipment for access control, turnstiles, cameras, alarms and smart lockers, through proprietary protocols and native SDKs from multiple vendors.
I developed the platform's real-time events microservice — hardware event capture, async queues and live distribution via SignalR — while also leading innovation initiatives: AI, voice, chatbot, BFF and new integrations.
