Rockstar🎓
Top SchoolRicardo Canastro is a seasoned software engineer with 11 years of experience building full-stack products and developer tools from Porto, Portugal. He has a strong track record as a founding engineer and lead developer—designing a hexagonal AI-driven user research platform, an in-house spreadsheet engine, and cross-platform desktop and mobile apps. Ricardo blends frontend expertise (React, Svelte, Flutter) with backend systems (Node.js, Postgres, Redis, event sourcing) and has shipped production-ready tooling around parsers and state machines using ANTLR and Dart. He also contributes to high-profile open-source projects, improving CI/CD and Dart support for the widely used ANTLR4 repository. Comfortable switching between hands-on implementation and architectural design, he often tackles hard engineering problems like building formula parsers, audio interview workflows, and performant canvas-based UIs. His background in both startups and large organizations gives him a pragmatic, product-focused approach to scalable system design.
