What I'm looking for

I'm looking for remote roles in Spain or the EU where I can build SaaS products and integrations, lead technical delivery, solve ambiguous real-world problems, and stay hands-on through production.

At Virto.Solar, I lead an integrations team while building and maintaining B2B SaaS integrations for enterprise customers and downstream partners. My work across Node.js, TypeScript, React, MongoDB and REST APIs contributed to a new customer subscription worth approximately €20K per quarter.

I take ambiguous business requirements from investigation through technical planning, implementation, testing, releases, deployments and production support. I also work directly with enterprise clients, support API partners, and diagnose incidents using application behaviour, logs, Grafana and the incident pipeline.

Previously at XOPS, I built APIs, backend services and background workers for an airport operations and fleet-management SaaS platform processing 10M+ daily events and equipment updates. I delivered Java, Spring, PostgreSQL, TypeScript, React, Redux and GraphQL capabilities, including a monitoring solution that became a key selling point for a new fleet-management system.
