Sobre mim
I fix web apps and backends that are slow, broken, or hard to maintain. I build new ones too. Web dev since 2016: JavaScript, TypeScript, React, Node.js. Rust has been my main language since 2024: APIs, backend services, CLI tools. One result I can name: a legacy PHP backend rewritten in Node.js, same public API, median response time about three times faster. Scrapers and parsers too, the kind that survive rate limits and JS-rendered pages. I work async, in writing: a short update each working day, fast replies, no calls. Past client work is under NDA, so I describe outcomes, not names.... Saiba mais
