Sandae Macalalag

Software Developer / Philippines

I have spent over 15 years building software, mostly on the backend, in Node.js, TypeScript, Java, PHP, and Perl across SQL and NoSQL databases. I care about the disciplines that keep a codebase alive over time: Domain-Driven Design, CQRS, clean architecture, object-oriented and functional programming, and distributed systems.
