Hi, I'm Rick
Software Engineer focused on backend systems, product engineering, and scalable web applications
About Me
I'm a software engineer with 5+ years of experience building backend systems, web applications, internal tools, and product-facing features across fintech and B2B SaaS. ciao
I’ve worked in startups and scaleups across Amsterdam, Barcelona, and Berlin, contributing to systems involving onboarding, KYC/KYB, document automation, public administration integrations, billing, microservices, and event-driven architecture.
I care about simple, well-designed software, strong product ownership, and solving real business problems without overengineering. I enjoy working across backend, frontend, architecture, and developer experience. ciao
