03 / About
A builder’s perspective.
An engineer’s approach.
I’m Bernard, a software engineer with 5+ years of experience building web, mobile, and SaaS applications. My work connects user-facing features with the systems that make them function: APIs, data models, authentication, payments, and deployments.
As co-founder and software engineer of NanoCare and MsoPak, I work across product development, mobile applications, backend architecture, and integrations. That breadth helps me see how individual technical decisions fit into a complete product.
