What I'm looking for

I’m interested in designing software where the business model guides technical decisions, balancing maintainability, performance, data consistency, and product evolution.

At runaID, I developed and maintained enterprise web applications, focusing on backend APIs, business logic, and system optimization. I worked on critical modules, improving performance and resolving data and integration issues.

I designed and optimized REST APIs and SQL persistence, and contributed to layered backend architecture, JWT authentication, and authorization. I also integrated frontend interfaces with APIs and databases, and participated in automated deployments.

I designed and developed Nexora, a SaaS platform for business management and commerce, end to end with Go, Vue 3, and PostgreSQL. I applied multi-tenant architecture, Clean Architecture, and transactional operations to support business workflows.
