Hi, I'm Willy 👋
I build cloud applications, APIs and integration-heavy systems, with 15+ years of experience across fintech, financial platforms and enterprise software.
Core technologies: TypeScript · Node.js · React · C# · .NET · AWS
I'm a software engineer and technical lead who designs and builds cloud applications, APIs, and integration-heavy systems. Since 2007, I've worked across financial platforms, enterprise SaaS, analytics, reporting, and data integration.
Alongside hands-on engineering, I work across solution design, technical leadership, team management, and delivery. I favour practical architecture that keeps systems understandable, reliable, and maintainable.

Featured project
A small document-management application for uploading, organising and securely accessing personal documents.
Users can create an account, upload PDF and image files, manage a draft-to-archived lifecycle, and open files through short-lived secure links. Database and Storage-level ownership rules keep documents private to each account.
I'm always happy to connect with people working on interesting engineering problems, fintech products, integrations, or cloud platforms.
