I'm a backend engineer at Mayasur Systems (Chetumal, Quintana Roo, Mexico). I design and ship production systems with a focus on:
- Clean architecture and modular monoliths over premature microservices.
- REST APIs, JWT auth, role-based access, multi-tenant patterns.
- PostgreSQL / SQL Server modeling and query optimization.
- Event-driven design with outbox patterns and CQRS-lite command buses.
- Offline-first systems for real LATAM operations (unreliable connectivity is part of the spec, not an edge case).
Currently building binexus-platform — a multi-industry, multi-tenant operational SaaS (POS, orders, inventory, routes, billing) on a modular-monolith foundation.
Languages: Spanish (native), English (B2).
