cat about.txt

I'm a software engineer with a soft spot for high‑performance, human‑feeling front‑ends. I've spent the last decade shipping product across Brazil, Poland, Czechia, and remotely — from early‑stage fintech to Microsoft Teams.

At Appcues I lead platform initiatives: TypeScript migrations, Webpack → Vite, cutting bundle size by 60%, and growing a design system. Before that I shaped Fluent UI at Microsoft and built trading dashboards at Credit Suisse.

I maintain ngx‑indexed‑db on the side, write on this site, and mentor whenever I get the chance. I care about craft, pace, and leaving a codebase kinder than I found it.

cat sobre.txt

Sou engenheiro de software com um carinho especial por front‑ends performáticos e humanos. Passei a última década entregando produto no Brasil, Polônia, Chéquia e remotamente — de fintech em estágio inicial ao Microsoft Teams.

Na Appcues lidero iniciativas de plataforma: migração para TypeScript, Webpack → Vite, redução de 60% no bundle e crescimento de um design system. Antes disso, moldei o Fluent UI na Microsoft e dashboards de trading no Credit Suisse.

Mantenho o ngx‑indexed‑db nas horas vagas, escrevo neste site e mentoro sempre que posso. Me importo com ofício, ritmo e deixar o código um pouco melhor do que encontrei.
