Rockstar🎓
Top SchoolLuís Afonso is a versatile software engineer and entrepreneur with 11 years of experience building cloud-native, secure, and scalable systems across back-end, mobile, and infrastructure. As Principal Engineer at YData and now running CookieBytes, he has led Kubernetes-based microservices, integrations with Kubeflow and DASK, and payment/device integration projects that bridge digital and physical checkout experiences. He blends hands-on coding (Python, Swift, Next.js, Cython) with architecture and delivery ownership—shipping production libraries to PyPI and implementing licensing and metering systems. A pragmatic technical lead, he prioritizes security (distroless images, multi-layer docker builds, custom auth/OIDC) and maintainability, reflected in open-source contributions to ydata-profiling focused on linting, typing and packaging. Based in Portugal, he pairs startup founder grit with deep systems experience and a knack for turning complex integrations into smooth user journeys.
