What I'm looking for

I'm seeking Golang backend development focused on REST API design, microservices, service reliability, debugging, and production support. I'm also interested in platform engineering work involving CI/CD, developer productivity, automation, regression testing, and resilient release workflows. I'm open to relocation and visa-supported opportunities in Spain, especially Barcelona, Madrid, and Valenci

At Aspire Software, I build and maintain Go backend services, develop reliable API workflows, and improve maintainability across production-grade systems. I also enhance REST API endpoints by translating business requirements into modular services and clean integration flows.

At Whitepeaks, I introduced Pest testing standards across Laravel services and supported production delivery by developing features and resolving defects. Earlier at Topup App, I designed GitHub Actions CI/CD pipelines that reduced release cycles from weekly to daily, and at Layer I developed Go APIs and a report-generation microservice.
