At 3Commas, I developed a Next.js application focused on performance, SEO, and server-side rendering. I led frontend optimization initiatives that raised mobile Lighthouse scores from 30 to 80 and improved Core Web Vitals.

I also built AI-powered localization pipelines for Prismic CMS, reducing manual translation effort across locales by 99%. I developed automation workflows for content creation and operations, and partnered with marketing stakeholders on SEO-driven features and landing pages.

Before 3Commas, I developed an e-commerce platform at CUBODROM using React, Node.js, and Express.js, including REST APIs and WebSocket features. At HIVEX, I built React and TypeScript interfaces and designed an Electron desktop app for internal workflows.
